Japan

Japan provides one of the richest historical settings for the study of radical Buddhism. From its early institutional development in Japan, Buddhism developed complex and often mutually supportive relationships with political authority, including the imperial court, the powerful religious institutions of the medieval period, and the Tokugawa shogunate. These relationships never eliminated conflict or dissent, however, and Japanese history also supplied later Buddhist radicals with memories and models of religiously inflected resistance, including peasant uprisings and traditions of the self-sacrificing “righteous person” (gimin 義民).

The political and intellectual upheavals accompanying the Meiji Restoration of 1868 transformed this relationship. Following the brief but severe persecution of Buddhism known as haibutsu kishaku 廃仏毀釈, Buddhist clergy and lay intellectuals pursued a variety of projects to reconstruct Buddhism as compatible with a modernizing nation-state, modern science, new forms of scholarship, and changing conceptions of religion and ethics. Within and against this broader field of Buddhist reform there emerged, from the 1880s through the early Shōwa period, a much smaller and internally diverse current in which activists brought Buddhist ideas into constructive engagement with socialism, anarchism, and eventually Marxism. This entry uses “radical Buddhism” primarily for these attempts to connect Buddhist thought and practice with fundamental transformations of existing social, economic, and political relations.

Radical Buddhism in this narrower sense never became a dominant current within modern Japanese Buddhism. Its most explicitly left-wing prewar expressions were repeatedly subjected to state repression, most dramatically in the High Treason Incident of 1910–1911 and the destruction of Seno'o Girō's Youth League for Revitalizing Buddhism in 1936–1937. Yet the questions these movements raised—about Buddhism's relationship to social inequality, capitalism, nationalism, war, and political authority—reappeared in different forms after 1945. The postwar critique of Buddhist complicity in Japanese militarism associated especially with Ichikawa Hakugen 市川白弦, and the later Critical Buddhism (Hihan Bukkyō 批判仏教) movement, are therefore treated here not as straightforward organizational continuations of prewar radical Buddhism but as later forms of Buddhist social and doctrinal criticism that can be situated within a broader genealogy of modern Japanese critical Buddhism.

Buddhism in Japan

Buddhism entered Japan from the Asian mainland in the sixth century CE and over the following centuries became deeply embedded in the country's political, economic, and cultural institutions. By the medieval period, major monasteries and temple networks controlled substantial landholdings and exercised considerable political influence. Kuroda Toshio 黒田俊雄 famously analyzed religious institutions as one component of the system of powerful elite blocs (kenmon 権門) through which court aristocrats, warriors, and major religious institutions constituted the medieval ruling order. The period also witnessed the development of influential Buddhist movements associated with figures such as Hōnen 法然, Shinran 親鸞, Dōgen 道元, and Nichiren 日蓮. Although some came into conflict with established religious and political authorities, Buddhist institutions generally developed through complex relationships of both autonomy and cooperation with political power rather than sustained opposition to it. Under the Tokugawa shogunate (1603–1868), these relationships acquired an extensive administrative form. Through temple registration (terauke 寺請) and hereditary temple-parishioner relationships (danka 檀家), Buddhist temples participated in the registration of households and regulation of religious affiliation while providing funerary and memorial services increasingly central to ordinary religious life.

The Meiji Restoration of 1868 profoundly disrupted this institutional settlement. The government-mandated separation of Buddhism and Shinto (shinbutsu bunri 神仏分離) was accompanied in many regions by anti-Buddhist violence and destruction conventionally known as haibutsu kishaku 廃仏毀釈, stripping Buddhist institutions of much of their former status and property and forcing Buddhist leaders to reconsider the tradition's place within the new nation-state. Responses ranged from renewed observance of the Buddhist precepts (kairitsu 戒律), associated with figures such as Fukuda Gyōkai 福田行誡 and Shaku Unshō 釈雲照, to participation in government-sponsored projects such as the Great Teaching (Daikyō 大教) campaign. A subsequent generation of scholar-priests and lay intellectuals—including Hara Tanzan 原坦山, Shimaji Mokurai 島地黙雷, Murakami Senshō 村上専精, Inoue Enryō 井上圓了, Shaku Sōen 釈宗演, and Kiyozawa Manshi 清沢満之—engaged modern science, philosophy, historical scholarship, and changing conceptions of religion. Historical-critical scholarship could pose particularly difficult questions for inherited authority: Murakami, for example, became associated with Daijō hibussetsuron 大乗非仏説論, the thesis that Mahāyāna scriptures were not directly taught by the historical Buddha. Modern Japanese Buddhist thought also intersected increasingly with academic philosophy, including the work of Nishida Kitarō 西田幾多郎 and the later Kyoto School.

By the 1930s and during the Asia-Pacific War, major Buddhist institutions accommodated themselves in varying degrees to the Japanese imperial state and its war effort. The extent and implications of this accommodation became an important subject of postwar Buddhist self-criticism, although sustained institutional reckoning developed only gradually. Ichikawa Hakugen's analysis of Buddhist war responsibility and “Imperial-Way Zen” (kōdō Zen 皇道禅) became one of the most searching examples of this critique. He examined not only particular instances of wartime collaboration but also the doctrinal, ethical, and institutional tendencies that had facilitated Buddhist accommodation to political authority. These developments form an important counterpoint to the much smaller traditions of progressive and radical Buddhism discussed below.

Radical Buddhism in Japan

The Radical Buddhism Project uses “radical Buddhism” in modern Japan primarily for attempts to bring Buddhist thought and practice into sustained engagement with projects for fundamental social, economic, or political transformation, particularly socialism, anarchism, and Marxism. Radical Buddhism was historically distinct from, although deeply indebted to, the broader currents of Buddhist reform and modernism described above, and its emergence cannot be traced to a single continuous tradition. Premodern revolts should therefore not be understood retrospectively as instances of “radical Buddhism.” They did, however, provide historical memories and symbolic models through which later activists could imagine religiously grounded resistance to established authority. The Ikkō-ikki 一向一揆 of the fifteenth and sixteenth centuries, for example, brought together religious communities, peasants, local warriors, and other groups associated with the Honganji branch of Jōdo Shinshū in episodes of armed resistance and regional self-government. Their aims and social composition varied considerably and cannot simply be assimilated to modern socialism or anarchism.

Of more demonstrable importance to modern radicals were Edo-period narratives of the self-sacrificing “righteous person” (gimin 義民), especially village representatives remembered for suffering or dying after petitioning authorities on behalf of oppressed peasants. The semi-legendary Sakura Sōgorō 佐倉惣五郎 (1605–1653) became an especially powerful exemplar, while Ōshio Heihachirō 大塩平八郎 (1793–1837), the Osaka samurai scholar and former official who led an 1837 rebellion during a period of severe famine, provided another model of principled resistance to corrupt authority. Their significance lies less in direct institutional or doctrinal continuity than in later appropriation. Such figures supplied what Shields describes as “root paradigms” of self-sacrificing resistance through which modern activists could interpret new conflicts involving poverty, capitalism, state authority, and social injustice. Uchiyama Gudō 内山愚童, for example, explicitly invoked earlier traditions of peasant resistance while articulating a thoroughly modern Buddhist anarchism. These appropriations did not make the earlier rebels socialists or anarchists retrospectively; rather, they allowed modern radicals to understand their political commitments through indigenous historical resources as well as newly imported ideas.

The Eastern Socialist Party (1882)

One of the earliest attempts in modern Japan to articulate a socialist political program through Buddhist and other East Asian concepts was the short-lived Eastern Socialist Party (Tōyō Shakaitō 東洋社会党), founded by Tarui Tōkichi 樽井藤吉 (1850–1922) in May 1882. Established amid the political ferment of the Freedom and People's Rights movement, the party was prohibited by the government the following month. Tarui nevertheless continued his efforts to revive it and circulated revised party regulations in January 1883, activity for which he was sentenced to a year in prison.

Tarui's draft party regulations reveal an eclectic attempt to formulate socialism through concepts drawn from Asian religious and ethical traditions rather than simply reproduce contemporary European socialist theory. Its first three principles made “affection” (shin'ai 親愛) the standard of words and actions, affirmed the “equality of self and other” (jita byōdō 自他平等), and identified the “greatest welfare” (saidai fukuri 最大福利) of society as the party's goal. Subsequent provisions proposed measures intended to overcome divisions between rich and poor, including forms of communal ownership.

Whether the Eastern Socialist Party should be regarded as “socialist” in the same sense as the socialist movements that developed in Japan around the turn of the twentieth century has long been debated. Some later commentators emphasized its distance from European socialist theory and situated it instead within the Freedom and People's Rights movement, agrarian demands for economic justice, and older East Asian ethical traditions. For the history of radical Buddhism, however, this ambiguity is itself significant. Tarui's experiment illustrates an enduring problem for later Buddhist socialists: whether socialism should be understood as a largely imported body of political and economic theory to which Buddhism might be added, or whether egalitarian and communal elements within Buddhist and other Asian traditions could themselves provide resources for constructing a distinctively local form of socialism.

Meiji Buddhist modernism

➣ Main article: Meiji New Buddhism

A more immediate context for the emergence of radical Buddhism was the Buddhist reform movement of the late Meiji period. These reformers were generally neither socialists nor political radicals, but they challenged established Buddhist institutions and helped develop a this-worldly, rationalized, and socially engaged conception of Buddhism that later radicals could push in more explicitly political directions. Particularly important were the short-lived Keiikai 経緯会 (Warp and Woof Society, 1894–1899), founded by the young Buddhist reformer Furukawa Isamu 古河勇 (also known as Rōsen 老川), and its successor, the Shin Bukkyō Dōshikai 新仏教同志会 (New Buddhist Fellowship, 1899–1915), initially known as the Bukkyō Seito Dōshikai 仏教清徒同志会 (Buddhist Puritan Fellowship).

The New Buddhists rejected what they regarded as the superstition, ritualism, sectarianism, and institutional privilege of “old Buddhism” while insisting upon the free investigation of Buddhism and other religions. Their program emphasized intellectual independence, ethical conduct, freedom from state interference, and the application of Buddhism to life in the present world. Particularly significant was their advocacy of genseshugi 現世主義 (this-worldliness), associated especially with Sakaino Kōyō 境野黄洋 and Tanaka Jiroku 田中治六. Rather than confining religion to the private sphere or locating the goal of Buddhism primarily in another world, the New Buddhists sought a Buddhism capable of addressing contemporary social and economic problems. For some members, this orientation acquired increasingly explicit social implications. Watanabe Kaikyoku 渡辺海旭 (1872–1933), who studied Sanskrit, Pāli, and Buddhist studies in Germany, became deeply involved in social welfare and brought Buddhist ethics into engagement with the social problems generated by industrialization. Inoue Shūten 井上秀天 (1880–1945), one of the Fellowship's more politically outspoken figures, developed a Buddhist pacifism sharply critical of rising nationalism. New Buddhists also entered into dialogue with contemporary socialists: Sakai Toshihiko 堺利彦, for example, contributed to Shin Bukkyō and challenged the movement to embrace a more thoroughly materialist interpretation of its ideas, a move its leading thinkers resisted.

The significance of Meiji New Buddhism for radical Buddhism therefore lies less in a direct political or organizational lineage than in the conceptual space it helped create. By questioning sectarian authority, defending freedom of intellectual inquiry, subjecting Buddhist doctrine and institutions to criticism, emphasizing this-worldly ethical practice, and insisting that Buddhism respond to contemporary social conditions, the New Buddhists helped loosen the identification of Buddhism with inherited institutions and established forms of authority. Later figures such as Takagi Kenmyō, Uchiyama Gudō, and especially Seno'o Girō would move considerably beyond this reformist position by bringing Buddhist ideas into direct engagement with socialism, anarchism, and Marxism.

Takagi Kenmyō

➣ Main article: Takagi Kenmyō

Takagi Kenmyō 高木顕明 (1864–1914), a priest of the Ōtani branch of Jōdo Shinshū, represents one of the earliest sustained attempts in modern Japan to articulate an explicitly socialist Buddhism. In 1899 he became resident priest of Jōsenji 浄泉寺 in Shingū, Wakayama Prefecture, where encounters with poverty, discrimination against burakumin 部落民, and social inequality contributed to his involvement with the socialist and antiwar movements. In his 1904 essay “Yo ga shakaishugi” 余が社会主義 (My Socialism), Takagi explicitly distinguished his socialism from that of Karl Marx and contemporary Japanese socialists, grounding it instead in his own Buddhist faith and practice. He interpreted Namu Amida Butsu 南無阿弥陀仏 as a call to equality, peace, and compassion, described Buddhism as “the mother of the common people and the enemy of the aristocracy,” and imagined the Pure Land as a society in which socialism was already realized. This vision underpinned both his opposition to the Russo-Japanese War and his call for communal life and the fundamental transformation of the existing social order.

Uchiyama Gudō

➣ Main article: Uchiyama Gudō

Uchiyama Gudō 内山愚童 (1874–1911), a Sōtō Zen priest and abbot of Rinsenji 林泉寺 near Hakone, developed one of the most explicitly anarchist forms of radical Buddhism in Meiji Japan. Uchiyama himself explained that, as a Buddhist missionary, he had been taught that all beings possess buddha-nature, that the Dharma is equal and without high or low, and that all beings are children of the Buddha. Discovering that these principles coincided with those of socialism, he wrote, led him to become a socialist. His radicalism soon extended from religious equality to a critique of private property, economic inequality, imperial authority, and militarism. Using a clandestine printing press at Rinsenji, he circulated writings advocating anarchist communism and calling upon ordinary people to free themselves from the political and religious beliefs sustaining the existing social order.

Uchiyama was arrested in 1909 after police discovered his clandestine printing operation and a quantity of dynamite at Rinsenji. Although his revolutionary rhetoric could be incendiary, Sanada argues that Uchiyama regarded violent revolution as premature and made publication and consciousness-raising his principal means of resistance. Already imprisoned for violations of publication and explosives laws, Uchiyama was subsequently drawn into the High Treason Incident (Taigyaku jiken 大逆事件), convicted of participating in the alleged conspiracy against Emperor Meiji, and executed on January 24, 1911. The Sōtō establishment expelled him from the priesthood in 1910 but formally restored his clerical status in 1993.

From the High Treason Incident to the YLRB

The High Treason Incident of 1910–1911 marked a severe rupture in the development of explicitly radical Buddhism in Japan. The execution of Uchiyama Gudō and imprisonment of Takagi Kenmyō formed part of a much broader suppression of socialist and anarchist activity, and in the political climate that followed, open attempts to combine Buddhism with revolutionary socialism or anarchism became exceptionally difficult. Buddhist social concern did not disappear, but during the 1910s it generally assumed less explicitly political forms. Itō Shōshin 伊藤証信 (1876–1963), for example, developed the ideal of muga-ai 無我愛 (selfless love), combining Buddhist ethical transformation, pacifism, and communal social practice while distancing himself from the increasingly dangerous language of socialism.

The 1920s nevertheless transformed the context in which Buddhist social thought operated. Labor and tenant movements expanded, socialist and Marxist ideas circulated increasingly widely, and Buddhist thinkers confronted new questions concerning poverty, capitalism, class, and the social responsibilities of religion. Responses ranged from anti-socialist apologetics to experiments in dialogue and selective appropriation; there was no continuous “radical Buddhist” movement linking the Meiji radicals to their successors. Seno'o Girō's emergence from the quite different world of reformist and nationalist Nichiren Buddhism illustrates both this discontinuity and the persistence of the underlying social questions. By the end of the decade, his growing criticism of capitalism and established Buddhism was preparing the ground for the Youth League for Revitalizing Buddhism.

Seno'o Girō and the Youth League for Revitalizing Buddhism

➣ Main article: Seno'o Girō

➣ Main article: Youth League for Revitalizing Buddhism

Seno'o Girō 妹尾義郎 (1889–1961) emerged from a quite different background from Takagi Kenmyō and Uchiyama Gudō. Raised in Jōdo Shinshū, he converted to Nichiren Buddhism as a young man and became an active lay leader in the reformist but strongly nationalist Nichirenshugi 日蓮主義 movement. During the 1920s, however, encounters with poverty and social conflict, dissatisfaction with established Buddhist institutions, and increasingly extensive reading in socialist and Marxist thought gradually transformed his outlook. By the end of the decade, Seno'o had come to regard capitalism itself as a fundamental source of suffering requiring structural transformation.

On April 5, 1931, Seno'o and a small group of young activists founded the Shinkō Bukkyō Seinen Dōmei 新興仏教青年同盟 (Youth League for Revitalizing Buddhism, YLRB) in Tokyo. Rejecting established Buddhist institutions as corrupt and declaring capitalism incompatible with the Buddhist spirit, the League sought to create a Buddha land in this world through both individual ethical transformation and fundamental social reform. During the following years it developed into a nationwide movement with branches across Japan, publishing journals and newspapers and participating in labor, tenant, antiwar, and antifascist activism. Its program became increasingly socialist and internationalist while retaining an explicitly Buddhist identity.

Seno'o's mature radical Buddhism combined Marxist social analysis with a this-worldly reinterpretation of Buddhist teaching. He treated Śākyamuni as an exemplary human being, interpreted the Dharma through interdependence, nonattachment, and selfless love (muga-ai 無我愛), and understood the Sangha as a model of cooperative social life. Structural transformation and ethical transformation were therefore mutually necessary: Buddhism could not retreat from material conditions, but neither could socialism succeed without transforming human relationships and desires. The YLRB's increasingly confrontational activism brought it under sustained police surveillance. Seno'o was arrested in December 1936 under the Peace Preservation Law and, after months of detention and interrogation, publicly recanted his former political position in 1937. A nationwide roundup later that year effectively destroyed the League.

Ichikawa Hakugen

➣ Main article: Ichikawa Hakugen

A different form of radical Buddhist critique emerged after Japan's defeat in 1945 in the work of the Rinzai Zen priest and scholar Ichikawa Hakugen 市川白弦 (1902–1986). Having himself participated in the intellectual world of wartime Japanese Zen, Ichikawa devoted much of his postwar work to examining Buddhism's responsibility for Japanese militarism and imperialism. Rather than attributing Buddhist support for the war simply to state coercion or individual failure, he asked what features of Buddhist doctrine, institutions, and historical relations with political authority had made such accommodation possible. His critique focused especially on what he called “Imperial-Way Zen” (kōdō Zen 皇道禅), in which Zen had become intertwined with emperor-centered nationalism and the Japanese war effort.

Ichikawa's critique was also reconstructive. His engagement with socialism, Marxism, anarchism, and postwar peace activism led him to ask what kind of Buddhism might resist rather than sanctify established power. He criticized inherited interpretations of karma, no-self, nonduality, harmony, and the “Middle Way” when they served to naturalize hierarchy, discourage political conflict, or obscure concrete injustice. At the same time, he recovered the suppressed history of Buddhist socialism represented by figures such as Takagi Kenmyō and Uchiyama Gudō and explored the possibilities of a more radical Buddhist politics. His mature thought thus directed criticism both outward, toward structures of domination, and inward, toward Buddhist doctrines and institutions themselves.

This insistence that Buddhism subject its own doctrines and historical formations to critical scrutiny makes Ichikawa an important precursor to the later movement known as Critical Buddhism (Hihan Bukkyō 批判仏教). Hakamaya Noriaki 袴谷憲昭 and Matsumoto Shirō 松本史朗 did not simply inherit Ichikawa's political program, and Critical Buddhism arose from different doctrinal and institutional controversies. The relationship is therefore better understood as a critical affinity than a direct intellectual succession.

Critical Buddhism

➣ Main article: Critical Buddhism

A later form of radical Buddhist self-criticism emerged in the 1980s around the Sōtō scholars Hakamaya Noriaki 袴谷憲昭 and Matsumoto Shirō 松本史朗. The movement known as Critical Buddhism (Hihan Bukkyō 批判仏教) subjected influential strands of East Asian Buddhist thought—particularly tathāgatagarbha (buddha-nature) and hongaku 本覚 (original enlightenment) thought—to sustained criticism. Hakamaya and Matsumoto argued that doctrines positing an underlying, universal ground of enlightenment risked obscuring the critical, relational, and non-substantialist dimensions of Buddhist teaching and could lend themselves to social accommodation rather than resistance. Hakamaya captured the movement's provocative stance in the proposition that “Buddhism is criticism” (Bukkyō wa hihan de aru 仏教は批判である). Critical Buddhism was neither a continuation of prewar Buddhist socialism and anarchism nor a reproduction of Ichikawa Hakugen's political project. Nevertheless, its insistence that Buddhist doctrines themselves be subjected to criticism—and its concern that appeals to harmony, nonduality, and original enlightenment could obscure discrimination and social injustice—places it within a broader genealogy of modern Japanese Buddhist self-criticism.

The Legacy of Radical Buddhism in Japan

Radical Buddhism never constituted a continuous movement or a major current within modern Japanese Buddhism. The Eastern Socialist Party disappeared almost immediately; Takagi Kenmyō and Uchiyama Gudō were destroyed by state repression; and the Youth League for Revitalizing Buddhism was dismantled in 1937. Nor did these movements establish an enduring institutional lineage after 1945. Their historical significance lies instead in recurrent attempts to ask whether Buddhist teachings could provide resources not merely for individual ethical reform or social welfare but for fundamental criticism and transformation of existing political and economic structures.

One explanation for the historical marginality of these experiments was offered by the comparative political scientist George O. Totten. Writing in 1960, Totten contrasted Japanese socialism with the avowedly Buddhist socialism of Burma's Anti-Fascist People's Freedom League. Whereas Burmese socialists were, in his formulation, “nationalists first and socialists second,” and could therefore draw upon a widely shared Buddhist idiom, Japanese socialists had been “socialists first and nationalists second,” emerging from competing Christian, secular, Marxist, and Buddhist currents. Influential Japanese Marxists such as Sano Manabu 佐野学 treated religion largely as a private matter destined to disappear, while efforts to bring Buddhism and Marxism into constructive engagement—including discussions involving Miki Kiyoshi 三木清 and Shinkō Kagaku no Hata no Moto ni 新興科学の旗のもとに (Under the Banner of the New Science), as well as Seno'o's YLRB—remained minority currents within the prewar left. Totten's comparison thus highlights an important feature of Japanese radical Buddhism: the relationship between Buddhism and socialism was neither assumed nor uncontested, but repeatedly had to be constructed.

The forms that relationship took varied considerably. Tarui Tōkichi drew upon Buddhist and other Asian ethical concepts in formulating an indigenous socialism; Takagi derived socialism from Jōdo Shinshū faith; Uchiyama brought Buddhist equality into conversation with anarchist communism; and Seno'o combined Buddhist ethical transformation with increasingly Marxist social analysis. Ichikawa Hakugen subsequently turned radical criticism back upon Buddhism itself, while Critical Buddhism extended this self-critical impulse in a different, primarily doctrinal direction. These projects constitute neither a single tradition nor variations on a common political ideology. Rather, they represent historically distinct efforts to rethink the relationship between Buddhism, power, equality, and social transformation.
