## Origins and family
Sakai was born in Buzen Province, in Nakatsu district Ōsaka village in what is now Miyako town, [Fukuoka Prefecture](https://www.edgepedia.org/fukuoka-prefecture), the third son of a lower-ranking samurai.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) The family soon moved to Toyotsu, where he attended the local primary school and graduated top of his class from Fukuoka Prefectural Toyotsu Middle School, the present Ikutokukan High School.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) He entered the First Higher School in Tokyo but was expelled for non-payment of tuition.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) Kotobank's encyclopedia entries describe him as the third son of a poor shizoku (former samurai) family, raised under the influence of the Freedom and People's Rights movement.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157)
## Career
Sakai began as a reporter for the Fukuoka Nichinichi Shimbun, the present Nishinippon Shimbun, before joining the Tokyo paper Yorozu Chōhō in 1899 ([Meiji 32](https://www.edgepedia.org/1899)). There he worked on home reform and promoted the [genbun itchi](https://www.edgepedia.org/genbun-itchi) style, the unified speech-and-writing movement, and his literary reputation as Sakai Kōsen grew.[1](https://www.ndl.go.jp/portrait/datas/6284) • [3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html)
The break of 1903 defined his public career. When the Yorozu Chōhō switched to supporting the [Russo-Japanese War](https://www.edgepedia.org/russo-japanese-war), Sakai left the paper with [Kōtoku Shūsui](https://www.edgepedia.org/kotoku-shusui) and [Uchimura Kanzō](https://www.edgepedia.org/uchimura-kanzo) in October 1903, and with Kōtoku he founded the Heiminsha (Commoners' Society) and launched the weekly Heimin Shimbun.[1](https://www.ndl.go.jp/portrait/datas/6284) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) The first issue declared the paper an organ for reaching a utopia of heimin-shugi (commoner-ism), socialism, and pacifism, and the chronology of the period records it as the only anti-war newspaper.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [6](https://c20jp.com/p/stosihik.html) In 1904, in the first-anniversary issue, Sakai and Kōtoku published their joint Japanese translation of the Communist Manifesto.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html)
In 1906 he helped found the [Japan Socialist Party](https://www.edgepedia.org/japan-socialist-party) with Katayama Sen and others, which the museum page identifies as the first legal socialist party in Japan, and became a council member.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) In June 1908 he was arrested in the Red Flag Incident, received a two-year sentence, and was released in September 1910; the timing meant he escaped arrest in the [High Treason Incident](https://www.edgepedia.org/high-treason-incident) (Kōtoku's case) of that year.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html)
After his release he founded the Baibunsha at the end of 1910, a writing and translation agency that gave impoverished socialist comrades a livelihood; [Ōsugi Sakae](https://www.edgepedia.org/osugi-sakae), Arahata Kanson, Takabatake Motoyuki, and Yamakawa Hitoshi joined it.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) In January 1914 he launched the magazine Hechima no Hana, retitled Shin Shakai (New Society) in September 1915, and took part in the universal suffrage and labor movements; according to Kotobank, he stood for the House of Representatives in 1917.[1](https://www.ndl.go.jp/portrait/datas/6284) • [4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157)
In July 1922 Sakai helped found the Japanese Communist Party, a secret organization, with Yamakawa Hitoshi, Kondō Eizō, Nosaka Sanzō, and Tokuda Kyūichi, and became its first chairman.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) Arrested in the First Communist Party Incident on June 5, 1923 and bailed that December, he left the party and turned to the legal proletarian-party movement.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) In 1927 he launched the magazine Rōnō (Workers and Peasants) with Yamakawa Hitoshi, and in 1928 he joined Suzuki Mosaburō in founding the Musan Taishūtō (Proletarian People's Party); in 1929 he was elected to the Tokyo City Assembly from Ushigome ward with the highest vote.[2](https://www.ndl.go.jp/portrait/e/datas/6284/) • [4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157)
## Political influence
Sakai's influence ran through organizations rather than office. He built the institutions of Japanese socialism in succession: the anti-war press of 1903, the first legal socialist party of 1906, the Baibunsha as a legal base for socialists during the repression after the High Treason Incident, the journal Shin Shakai, and finally the proletarian parties of the late 1920s.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html) Kuroiwa Hisako's prize-winning biography describes the Baibunsha as Japan's first editorial production company and foreign-language translation company, created after the High Treason Incident to give activists a livelihood, a meeting place, and education for young socialists.[7](https://www.kodansha.co.jp/book/products/0000186214) His last political act was institutional as well: at the Manchurian Incident of 1931 he became chairman of the Zenkoku Rōnō Taishūtō's committee opposing the dispatch of troops to China, and maintained an anti-war stance until his death.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [5](https://www.nagaragawagarou.com/visualmuseum/m-toshihiko.html)
## Death and successors
Sakai died on January 23, 1933.[1](https://www.ndl.go.jp/portrait/datas/6284) • [4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) Within the socialist movement Yamakawa Hitoshi was a close collaborator, with whom he edited Rōnō and built the proletarian parties after Sakai's departure from the Communist Party.[2](https://www.ndl.go.jp/portrait/e/datas/6284/) • [4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) In February 1931 he had opened a terakoya-style agricultural school in Yukuhashi, Fukuoka Prefecture.[6](https://c20jp.com/p/stosihik.html)
## Historians' assessment
Japanese reference works and his birthplace municipality treat Sakai as a founding figure, the father of Japanese socialism, who devoted his life to pioneering the movement across three imperial reigns.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) • [4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) A doctoral thesis on early Japanese socialism reads Sakai together with Yamakawa Hitoshi and [Yamakawa Kikue](https://www.edgepedia.org/yamakawa-kikue) as theorists who consciously addressed the gendering of men, arguing that early Japanese socialist thought included critiques of androcentrism and male supremacy, while noting a persistent tension between that theoretical critique and practice in which men's role as political subject took precedence.[8](https://hdl.handle.net/10803/697718)
The [National Diet Library](https://www.edgepedia.org/national-diet-library) gives Meiji 3, 11th month 25th day, corresponding to January 15, 1871,[1](https://www.ndl.go.jp/portrait/datas/6284) • [2](https://www.ndl.go.jp/portrait/e/datas/6284/) while the [Great Soviet Encyclopedia](https://www.edgepedia.org/great-soviet-encyclopedia) gives February 25, 1870, and the Miyako town page's heading dates his life from 1870.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) • [9](https://encyclopedia2.thefreedictionary.com/Sakai+Toshihiko) The death date, January 23, 1933, is consistent across sources.[1](https://www.ndl.go.jp/portrait/datas/6284) • [9](https://encyclopedia2.thefreedictionary.com/Sakai+Toshihiko)
## Legacy
In 1960, for the 90th anniversary of his birth, a memorial monument was erected at Toyotsu; a memorial hall followed in 1973, and its artifacts were moved to the Miyako Town History and Folklore Museum in 2012.[3](https://www.town.miyako.lg.jp/rekisiminnzoku/kankou/person/sakai_toshihiko.html) The Ohara Institute for Social Research at Hosei University holds notes on Kōtoku's copy of the Communist Manifesto purchased from Sakai, and materials related to a [Comintern](https://www.edgepedia.org/comintern) platform draft associated with him.[10](https://oisr-org.ws.hosei.ac.jp/about/genbutsu_list/?title=%E5%A0%BA%E5%88%A9%E5%BD%A6++%28Sakai%2C+Toshihiko%29) His 1904 co-translation of the Communist Manifesto with Kōtoku Shūsui is recorded in reference works.[4](https://kotobank.jp/word/%E5%A0%BA%E5%88%A9%E5%BD%A6-18157) • [9](https://encyclopedia2.thefreedictionary.com/Sakai+Toshihiko)
