(27 December 1876 â 5 October 1948) was a Japanese Buddhist leader and explorer who was the 22nd Abbot of Nishi Hongan-ji and the head of the Honganji-ha sect of Buddhism. He is known for expeditions to Buddhist archaeological sites in Central Asia, such as Subashi Temple near Kucha. His Dharma name was .
Between 1902 and 1910, he financed three expeditions to Central Asia, although his participation was stopped for his succession. Ã Âtani was a fellow of the Royal Geographical Society and hosted several fellow explorers, such as Sven Hedin and Albert von Le Coq. His collection, often called "Ã Âtani collection" is still considered crucial in Central Asian studies, although it is today scattered across Tokyo, Kyoto, China and Korea. In addition to his spiritual responsibilities and his Central Asian activities, Ã Âtani wrote about China, Manchuria and Chinese porcelain. During the Great Game, British and Russian intelligence both suspected that his archaeological expeditions were little more than covers for espionage. Japan says they were solely investigations of the route along which Buddhism came to Japan and had no political connections.
After his father à Âtani Kà Âson's death, he succeeded as Abbot of Nishi Hongan-ji in 1903. He also devoted himself to modernizing Jà Âdo Shinshà «, but his sponsorship incurred substantial debt for his sect. A financial scandal forced him to abdicate in 1914. His nephew, à Âtani Kosho, became the 23rd Abbot.
