Named in memory of Souseki Natsume (1867–1916), a distinguished Japanese scholar in English literature who has left an indelible mark on the history of Japanese modern literature with Ougai Mori in the Meiji era, and whose brain is still kept in the medical department of Tokyo University. Many of his articles are still widely read and have been made into movies. One of the best known articles, Botchan, which means a greenhorn in English, is set in Shikoku, the island on which the Geisei {see planet  (2571)} station is located. (M 16246) _ _.
