Japan presents one of the richest and longest-running case studies in radical Buddhism: a nation in which Buddhist institutions were, for most of their history, deeply "imbricated" with secular power, whether the imperial court, the medieval temple-complexes (権門 kenmon) of Heian and Kamakura Japan, or the shogunates of the Edo period, yet in which recurrent episodes of peasant unrest, sectarian reform, and modern political radicalism repeatedly generated dissident readings of the Dharma. The Meiji Restoration of 1868 subjected Buddhism to a short but severe wave of state persecution (廃仏毀釈 haibutsu kishaku), after which successive generations of clergy and lay intellectuals sought to "modernize" the tradition along scientific, ethical, or nationalist lines. Out of this same ferment, and drawing on older domestic traditions of righteous peasant revolt, a much smaller current of explicitly left-wing "radical Buddhism" emerged in the late Meiji, Taishō, and early Shōwa periods, fusing Buddhist doctrine with anarchism, socialism, and Marxism. This current was violently suppressed by the prewar state but left a legacy of postwar self-criticism, most systematically in the postwar critique of wartime Zen associated with Ichikawa Hakugen and, decades later, in the "Critical Buddhism" (批判仏教 hihan Bukkyō) movement's reassessment of Buddhist doctrine's complicity with social quietism.

Buddhism in Japan

Buddhism entered Japan from the Asian mainland in the sixth century CE and, over the following centuries, became closely interwoven with both the imperial court and successive ruling elites. By the Heian and Kamakura periods (794–1333), major temple complexes had evolved into powerful landholding institutions, functioning, in the analysis of Kuroda Toshio (黒田俊雄), as one of several elite factions (kenmon) that jointly constituted the ruling order alongside the court aristocracy and the warrior class. The Kamakura period also saw the emergence of the great popular sectarian movements, Pure Land (浄土 Jōdo), True Pure Land (浄土真宗 Jōdo Shinshū), Zen, and Nichiren (日蓮) Buddhism, several of which would later furnish vocabularies and precedents for socially engaged and even insurrectionary forms of Buddhist practice discussed below. Despite a handful of dramatic exceptions, such as Oda Nobunaga's (織田信長) 1571 destruction of the Enryakuji (延暦寺) temple complex on Mount Hiei, the dominant historical relationship between the sangha and the Japanese state was one of symbiosis rather than either fusion (as in Tibet) or sustained antagonism: temples retained considerable autonomy over their own internal affairs while providing ritual and ideological support, including funerary and family-registry services, for the ruling authorities.

This symbiosis reached its most administratively complete form under the Tokugawa shogunate (1603–1868), when, despite the regime's own sympathies with Neo-Confucianism, the parish (檀家 danka) temple registration system made Buddhist institutions into a de facto arm of state surveillance and, in effect, established Buddhism as the country's civil religion. The Meiji Restoration of 1868 shattered this arrangement almost overnight. Framed by its architects less as a "restoration" than as a wholesale invention of a modern nation-state centered on the emperor, the new government briefly promoted a policy of "throw away the Buddha and abolish Śākyamuni" (haibutsu kishaku), under which the number of Buddhist temples fell from roughly 450,000 to some 70,000 and the number of ordained priests from about 75,000 to under 20,000 within a few years. Persecution proper ended by 1873, but Buddhist leaders remained under sustained pressure to prove the tradition's compatibility with a nationalist, modernizing Japan, prompting Buddhist priests such as Fukuda Gyōkai (福田行誡) and Shaku Unshō (釈雲照) to launch the kairitsu (戒律, precepts) reform movement, an attempt to rehabilitate Buddhism's public image through a renewed emphasis on monastic discipline and, more ambivalently, through active participation in state-sponsored nationalist campaigns such as the Great Teaching (大教 Daikyō) movement of the 1870s.

A subsequent generation of scholar-priests, 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), modeled their reformist efforts less on the kairitsu movement than on the secular "Civilization and Enlightenment" movement (文明開化 bunmei kaika) associated with Fukuzawa Yukichi (福沢諭吉), seeking to "modernize" Buddhist doctrine and apologetics along scientific, historicist, and ethical lines without going so far as to abandon the tradition outright. One influential strand of this so-called "Buddhist Enlightenment," associated above all with Murakami Senshō and known pejoratively as Daijō hibussetsuron (大乗非仏説論, "the theory that Mahāyāna is not the true teaching of the Buddha"), applied historical-critical method to argue that much of Mahāyāna doctrine represented a later accretion rather than the Buddha's original teaching, provoking sustained controversy within the established sects. A related but philosophically distinct modernist current emerged from Nishida Kitarō's (西田幾多郎) Kyoto School, which grounded a specifically aesthetic and existentialist interpretation of Zen in the concept of "pure experience" (純粋経験 junsui keiken) and, in Nishida's later writings on basho (場所, "place"), came to furnish, however unintentionally, a philosophical vocabulary that was mobilized in support of wartime Japanese ultranationalism.

Institutional Buddhism's accommodation with Japanese imperialism deepened through the Fifteen Years' War (1931–1945). D. T. Suzuki (鈴木大拙) himself would later argue that Zen had "sustained" the wartime military classes both morally, through its injunction never to look back once a course of action is decided, and philosophically, through its indifference to life and death. In the immediate postwar period, the major sects faced little internal reckoning with this record, and it was this silence, more than any single doctrinal dispute, that would provide the immediate context both for the postwar critique associated with Ichikawa Hakugen and, a generation later, for the "Critical Buddhism" movement (see below). Since 1945, Buddhist institutions in Japan have continued to combine widespread ritual and funerary functions with a much-diminished public role, alongside the continued growth of lay new religious movements with roots in Nichiren Buddhism, such as Sōka Gakkai (創価学会) and Risshō Kōseikai (立正佼成会).

Radical Buddhism in Japan

The Radical Buddhism Project treats twentieth-century Japanese "radical Buddhism," the deliberate fusion of Buddhist doctrine with anarchism, socialism, or Marxism, as historically distinct from, if indebted to, the broader current of Meiji Buddhist reform described above. Three overlapping sets of precedent are relevant to its emergence: older domestic traditions of religiously inflected peasant protest; an abortive but instructive early attempt to found an explicitly "Buddhist" socialist party in the 1880s; and the more immediate, self-consciously "modernist" Buddhist reform movements of the 1890s and early 1900s.

Among the peasant precedents, the ikkō-ikki (一向一揆) revolts of the Muromachi period (1336–1573), in which farmers, monks, and some nobles rose against samurai rule under the banner of Amida Buddha and Jōdo Shinshū teaching, provided an early template for collective, religiously legitimated resistance to secular authority. Even more influential for later radicals was the Edo-period tradition of the martyred peasant representative (義民 gimin), exemplified by the semi-legendary farmer Sakura Sōgorō (佐倉惣五郎, 1605–1653) and by the samurai scholar-rebel Ōshio Heihachirō (大塩平八郎, 1793–1837), whose 1837 uprising in Osaka, inspired by Wang Yangming Neo-Confucianism, combined an appeal to imperial and shogunal ideals of "benevolent government" with an explicit call to redistribute the wealth of merchants and officials to the poor. Shields argues that these narratives, whatever their outcome, functioned as "root paradigms" that later Buddhist socialists and anarchists, including Uchiyama Gudō, consciously invoked as models of principled, self-sacrificing resistance to illegitimate authority.

The Eastern Socialist Party (1882)

The earliest attempt to fuse Buddhist vocabulary explicitly with a socialist political program, predating the New Buddhist Fellowship discussed below by nearly two decades, was the short-lived Eastern (or Oriental) Socialist Party (東洋社会党 Tōyō Shakaitō, 1882), founded by the pan-Asianist activist Tarui Tōkichi (樽井藤吉, 1850–1922). Suppressed by the government within months of its founding, the party's draft regulations nonetheless framed its socialist principles, "sincere love," the "equality of self and other" (自他平等 jita byōdō), and "the greatest welfare for the general public", in avowedly Buddhist and Daoist terms, invoking the Lotus Sutra's image of a single "rain" of the Dharma falling equally on all beings and describing party members as "children of the Buddha" (仏子 busshi) with a special compassionate mandate toward the poor. As the historian Akamatsu Katsumaro (赤松克麿) later observed, the party "was not based on Western socialism [but rather] espoused a peculiar socialist blend of traditional Asian Buddhism and Taoism," and most subsequent socialists and scholars have judged Tarui's movement to fall short of "actual" socialism owing to its lack of sophisticated economic analysis and its heavy reliance on traditional religious idiom, an assessment that nonetheless established, at the very outset of the modern Japanese left, the recurring tension between indigenizing socialism in Buddhist terms and satisfying the doctrinal expectations of secular Marxists.

Meiji Buddhist modernism

➣ Main article: Meiji New Buddhism

The second, more moderate precedent current, Meiji Buddhist modernism proper, produced organizations considerably more cautious than later radical Buddhism but which nonetheless established a "this-worldly," socially engaged reading of the Dharma on which later figures would draw. The short-lived Warp and Woof Society (経緯会 Keiikai, 1894–1899), founded by the young Buddhist reformer Furukawa Isamu (古河勇, also known by his art-name Rōsen 老川), and its successor, the New Buddhist Fellowship (新仏教同志会 Shin Bukkyō Dōshikai, 1899–1915; known in its earliest years as the Buddhist Puritan Fellowship, 仏教清徒同志会), rejected both the "old Buddhism" of ritual and institutional privilege and any straightforward state sponsorship of religion, advocating instead the "free investigation" of Buddhism and other faiths, the destruction of superstition, and a "sound faith" grounded, in the words of co-founder Sakaino Kōyō (境野黄洋), in an explicitly "pantheistic" this-worldliness (現世主義 genseshugi). The term itself is usually credited to fellow founding member Tanaka Jiroku (田中治六, 1869–?), who grounded it in Inoue Enryō's realist metaphysics. Fellow founding member Watanabe Kaikyoku (渡辺海旭, 1872–1933), a priest who had studied Buddhism, Sanskrit, and Pāli in Germany for a decade, extended this this-worldly orientation into an early social-democratic critique of the human costs of industrial capitalism, while the widely traveled Inoue Shūten (井上秀天, 1880–1945), the Fellowship's most radical member, emerged from encounters with Dharmapāla, Taixu, and Uchiyama Gudō as a committed pacifist opposed to Japanese imperial war. Although the New Buddhists' own political engagement rarely went beyond mild protest and journalism, and they explicitly distanced themselves from Marxist "materialism," their insistence that authentic Buddhist faith entailed active, this-worldly engagement with poverty and injustice, and their willingness to collaborate with contemporary socialists such as Sakai Toshihiko (堺利彦), mark them as important forerunners of the more thoroughgoing Buddhist socialism of the 1920s and 1930s.

Takagi Kenmyo

➣ Main article: Takagi Kenmyo

The first sustained fusion of Buddhist doctrine with explicitly revolutionary politics, rather than reformist social engagement, emerged only in the final years of the Meiji period, in the person of the Ōtani-branch Shin Buddhist priest Takagi Kenmyō (高木顕明, 1864–1914). Appointed head priest of Jōsenji (浄泉寺) in Wakayama Prefecture in 1899, Takagi ministered to a parish composed largely of burakumin (部落民) parishioners, whose combined experience of caste discrimination and economic hardship drove his turn toward socialist activism. In his unpublished 1904 essay Yo ga shakaishugi (余が社会主義, "My Socialism"), Takagi grounded his politics not in Marxist materialism, which he explicitly disavowed alongside the more secular and anti-religious socialism of Kōtoku Shūsui (幸徳秋水) and Sakai Toshihiko, but in the Shin Buddhist doctrine of tariki (他力, Other-power) and the nembutsu (念仏) invocation of Amida Buddha, arguing that "the Land of Bliss is the place in which socialism is truly practiced" and that genuine faith required a "revolution of thought" (shisō no kaiten) expressed through concrete social welfare. On this basis he condemned Japan's war with Russia, denounced fellow clergy who blessed soldiers with promises of rebirth in the Pure Land, and declared Buddhism to be "the mother of the common people and the enemy of the nobility." Charged with complicity in the fabricated conspiracy prosecution known as the High Treason Incident (大逆事件 Taigyaku jiken, 1910–1911) alongside Uchiyama Gudō and the Rinzai priest Mineo Setsudō (峰尾節堂), Takagi had his death sentence commuted to life imprisonment; defrocked by his sect on the date of his sentencing, he died by apparent suicide in prison in 1914. Higashi Honganji (東本願寺) formally rehabilitated him only in 1996, going so far as to credit him with a guiding role in the sect's subsequent social-reform efforts.

Uchiyama Gudo

➣ Main article: Uchiyama Gudo

Uchiyama Gudō (内山愚童, 1874–1911), abbot of the small Sōtō Zen temple Rinsenji (林泉寺) near Hakone, ran a clandestine printing press beneath his temple's altar, through which he distributed Japanese translations of Western anarchist writings and his own tract Museifu Kyōsan Kakumei (無政府共産革命, Anarchist Communist Revolution, 1908), grounding an anarchist-communist program directly in the Buddhist doctrines of universal Buddha-nature and the equality of the Dharma. Both this tract and his Heibon no jikaku (平凡の自覚, "Ordinary Self-Awakening") return repeatedly to the compound motto anraku jiyū (安楽自由), "comfort and freedom", which Uchiyama treats as both a Buddhist existential awakening and a Western-style political liberty, and he further modeled his anarcho-communism on what he took to be the simple, communal life of the early Chinese Chan sangha. Convicted on publication and explosives charges in 1909, he was drawn into the High Treason Incident the following year and executed in 1911 at the age of thirty-six. He remains unusual among Buddhist radicals of his era for his open advocacy of revolutionary violence, and the Sōtō sect did not formally rehabilitate him until 1993.

In the immediate aftermath of the High Treason Incident, socialist and anarchist sympathies within Japanese Buddhism did not disappear, but they largely went underground, resurfacing, if at all, in depoliticized or euphemistic form. Itō Shōshin (伊藤証信, 1876–1963), a correspondent of Uchiyama's, abandoned the term "socialism" altogether in favor of muga-ai (無我愛), "selfless love," a doctrine blending Buddhism, pacifism, and a residual social concern that carefully avoided any open association with the revolutionary left. A similar retreat into an apolitical, Tolstoyan agrarian utopianism characterizes the Nichiren-affiliated poet Miyazawa Kenji (宮沢賢治, 1896–1933), now remembered chiefly for his fiction and verse rather than for any social program. It was against this quiescent background that Seno'o Girō would reintroduce an explicitly political Buddhist socialism two decades later.

Seno'o Giro and the Youth League for Revitalizing Buddhism

➣ Main article: Senoo Giro

➣ Main article: Youth League for Revitalizing Buddhism

The most theoretically developed and organizationally sustained experiment in prewar Japanese Buddhist socialism was led by the lay Nichiren activist Seno'o Girō (妹尾義郎, 1889–1961), who broke over the course of the 1920s with the nationalist Nichirenshugi movement of Tanaka Chigaku (田中智学) and Honda Nisshō (本多日生) and turned instead toward Marxism and anti-fascist internationalism. In April 1931 Seno'o founded the Shinkō Bukkyō Seinen Dōmei (新興仏教青年同盟, Youth League for Revitalizing Buddhism), which argued that Buddhism, properly understood, was atheistic, materialist, and revolutionary, and which fused a reinterpreted Buddhist Three Refuges with an explicit commitment to anti-capitalist and anti-militarist politics. The League became one of the few explicitly Buddhist participants in the mid-1930s popular front movement, joining Katō Kanjū's (加藤勘十) Proletarian Party of Japan (日本無産党 Nihon Musantō) in 1936, before its suppression by the state in 1936–1937, following Seno'o's arrest and forced political recantation (転向 tenkō). Seno'o's fusion of Buddhism and Marxism was distinctive in insisting that the two were not merely compatible but coextensive: "the process of liberating the oppressed from suffering is nothing other than Buddhist awakening."

Ichikawa Hakugen

➣ Main article: Ichikawa Hakugen

Writing in the postwar period, the Rinzai Zen priest and philosopher Ichikawa Hakugen (市川白弦, 1902–1986) became the foremost internal critic of what he termed "Imperial-Way Zen" (皇道禅 kōdō Zen), the wartime alignment of Japanese Zen institutions, and of Nishida-school philosophy, with state militarism and emperor-centered ideology. A professor at Hanazono University in Kyoto, Ichikawa devoted much of his postwar career to documenting Buddhist institutional complicity in Japanese imperialism, including his own wartime compromises, while developing a systematic "Buddhist-Anarchist-Communism" that grounded anarchist politics and communist economics in the Prajñāpāramitā concept of emptiness (空 kū). In his major study Bukkyōsha no sensō sekinin (『仏教徒の戦争責任』, The War Responsibility of Buddhists, 1970), Ichikawa isolated twelve specific doctrinal and cultural factors that he held responsible for hindering the emergence of a fully developed Japanese Buddhist socialism, including the traditionally close, mutually supportive relations between Buddhism and the state, the doctrine of karma as a rationalization of social inequality, Confucian-derived ethics of hierarchy and harmony, the doctrine of no-self as an obstacle to reflection on rights and justice, the Buddhist self-identification as the "Middle Way," which he held had fostered a conformist, compromising disposition ill-suited to political dissent, and the Zen and Pure Land privileging of "peace of mind" (安心 anshin) over justice. Shields groups these twelve factors into two broad categories, deeply embedded features of Japanese and East Asian culture more generally (such as institutional conservatism and ancestor worship), and specifically Mahāyāna doctrines subject to a wide range of interpretation, and argues, against a purely doctrinal reading of Buddhist wartime complicity, that the former category bears the greater share of responsibility, since doctrine always remains open to reinterpretation in a way that deeply ingrained cultural practice does not. Ichikawa's work remains the central reference point for postwar Japanese Buddhist self-criticism and directly prefigures, both in method and in target, the "Critical Buddhism" movement discussed below.

Critical Buddhism

Although chronologically and institutionally distinct from the prewar radicals discussed above, "Critical Buddhism" (批判仏教 hihan Bukkyō) represents the most theoretically ambitious postwar development of the same underlying project, an attempt to hold Buddhist doctrine accountable to standards of social justice, and is treated by the Radical Buddhism Project as a direct intellectual heir to this earlier tradition. The movement was launched in the late 1980s by two Sōtō Zen-affiliated scholars, Hakamaya Noriaki (袴谷憲昭) and Matsumoto Shirō (松本史朗), whose work was galvanized in part by a 1979 incident in which Machida Muneo (町田宗夫), then secretary-general of the Sōtō sect, publicly denied that any social discrimination existed in Japan, in direct response to a draft World Conference on Religion and Peace statement of concern for the burakumin. Hakamaya and Matsumoto argued that authentic Buddhism was, at its core, critica, a commitment to rational, discriminating analysis rooted in the doctrine of dependent origination (pratītya-samutpāda), and that this criticalism had been progressively displaced across the history of East Asian Buddhism, and above all within Zen, by topica, an aesthetic monism of harmony, holism, and "original enlightenment" (本覚 hongaku) thought that the Critical Buddhists trace to the controversial doctrine of the womb or matrix of Buddhahood (tathāgatagarbha). On this basis, they mounted a sweeping and highly polemical attack on prominent modern Japanese thinkers, including D. T. Suzuki, Nishida Kitarō, and Nishitani Keiji (西谷啓治) of the Kyoto School, and even on their own Sōtō sect, arguing that Zen's ethical failures during the wartime period were less an aberration than the natural culmination of topicas neglect of critical, discriminating ethics. Scholars including Paul Swanson have distinguished three levels at which the Critical Buddhist analysis of Zen operates: a Buddhological critique of the historical misuse of doctrines such as Buddha-nature; a sectarian critique of Sōtō Zen's own departure from the teachings of its founder, Dōgen (道元, 1200–1253); and a social critique linking both to Buddhist institutional apathy or collaboration under Japanese wartime nationalism.

Although Critical Buddhism has no direct organizational lineage to the prewar Buddhist socialists and anarchists discussed above, Shields argues that it belongs to a recognizable genealogy of "critical" Japanese Buddhism stretching back through the New Buddhist Fellowship and, especially, Seno'o Girō's Youth League for Revitalizing Buddhism, both of which anticipated the Critical Buddhists' rejection of "topicalist" harmony and quietism, if from an explicitly socialist rather than a primarily doctrinal or philosophical standpoint. Critics have nonetheless noted the limitations of Critical Buddhism as a vehicle for radical social critique in its own right: unlike Seno'o or the New Buddhists, Hakamaya and Matsumoto offer little sustained analysis of political economy, and Shields has proposed supplementing their "criticalism" with the historical-materialist ideology critique of Karl Mannheim and Karl Marx, and with the Nichiren-derived utopian tradition running from Tarui Tōkichi through Seno'o Girō, in order to give Critical Buddhism's largely individualistic, liberal-humanist framework a more thoroughly structural or "materialist" account of Buddhist social praxis.

The Legacy of Radical Buddhism in Japan

The comparative political scientist George O. Totten, writing in 1960, offered an early and still-instructive explanation for why prewar Japanese radical Buddhism remained comparatively marginal by contrast with, for instance, the avowedly Buddhist socialism of the Burmese Anti-Fascist People's Freedom League: whereas Burmese socialists were, in his formulation, "nationalists first and socialists second," reconciling an already unifying national faith with imported Marxist categories, Japanese socialists had been "socialists first and nationalists second" from the movement's 1890s origins, arriving at their social consciousness through a variety of competing and often mutually hostile paths (Christian, secular-Marxist, and Buddhist) that left the movement chronically fragmented by schism rather than unified around a shared religious idiom. Totten further notes that early Japanese Marxist theorists such as the Communist theoretician Sano Manabu (佐野学) explicitly regarded religion as a private affair to be dissolved rather than harnessed, while such attempts as were made to bridge Buddhism and Marxism, for instance by the philosopher Miki Kiyoshi's (三木清) circle around the journal Shinkō Kagaku no Hata no Moto ni (新興科学の旗のもとに, "Under the Banner of the New Science") and by the Youth League itself, remained a minority position within the broader prewar Japanese left. Together with Ichikawa Hakugen's later, structurally similar critique, this comparative account underscores a recurring theme of the Radical Buddhism Project's Japan entries: that Japanese radical Buddhism arose less from any inherent affinity between Buddhist doctrine and left-wing politics than from the deliberate, always contested, and frequently short-lived efforts of individual monastics and lay activists to force such an affinity into being against the weight of institutional conservatism and rival, secular currents on the Japanese left.

The broader legacy of prewar radical Buddhism in Japan is, in consequence, more often one of rupture than continuity: the High Treason Incident of 1910–1911 and the suppression of the Youth League in 1936–1937 together account for the near-total absence of any organized Buddhist political dissent in Japan between the early 1910s and 1945. Postwar developments, including Ichikawa's critique of wartime complicity, the participation of some Buddhist clergy in the antiwar Beheiren (ベ平連) movement of the 1960s and 1970s, the emergence of Critical Buddhism, and the Marxist social-policy scholar Kōhashi Shōichi's (孝橋正一) 1968 attempt to rehabilitate the Youth League's Buddhist socialism from outside Buddhist institutions altogether, as an unrealized dialectical synthesis of Buddhist compassion and social-scientific method, are best understood as a delayed reckoning with, rather than a direct organizational continuation of, this earlier radical tradition.
