Geographical Imagination is an intellectual biography of Ishikawa Sanshirō (1876-1956), a Japanese anarchist active during the first half of the 20th century and a staunch opponent of any form of authoritarianism throughout his life. The book traces his travels, encounters, and ideological engagements, as he opposed war with Russia in the early 1900s, spent several years of self-imposed exile in France and Belgium in the 1910s, and explored European ideas – from anarchism and geographical thought to anti-Darwinism and ecological living. Ishikawa's life and writings bear testimony to Japan's undercurrent of political dissent and transnational revolutionary connections during the modern period.
