Iwasa Sakutarō
Japanese anarchist

Sakutarō Iwasa (岩佐 作太郎, Iwasa Sakutarō; 1879–1967) was a Japanese anarchist who was involved in the Japanese anarchist movement during the 20th century. Living until the age of 87, he was significant in influencing Japanese anarchists towards his anarcho-communist variety of 'pure' anarchism.
It was said about him after his death that "the road which the aged Iwasa walked, extending through the Meiji, Taishō and pre-war and post-war Shōwa eras, was the history of the Japanese anarchist movement itself."
Early life
Sakutarō Iwasa was born in 1879, in a farming hamlet in Chiba Prefecture in Japan. His father was a wealthy land-owning farmer, and was the headman of five villages. His grandfather had been too, and had encouraged communal production on the farms which he oversaw, resulting in a "half-communist village". This influenced Iwasa to believe in the possibility of anarchist forms of organisation from a young age.
He received a traditional primary education, but dropped out of middle school due to boredom with his studies. He progressed to Tokyo Law College, and wished to drop out once more, but his mother encouraged him to press on to graduation in 1898. He was exposed to Christianity, but did not himself become Christian, arguing that "Jesus was a person. Buddha and Confucius were persons.

The linked authority identifier is Q28692233. VIAF identifies the subject as 12157667. The Library of Congress control number is nr90018519. 3 of 4 selected statements include explicit references; 0 carry qualifiers and 1 use preferred rank.

The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
