80184 Hekigoto           Discovered 1999 Nov. 10 by A. Nakamura at Kuma Kogen.
Hekigoto Kawahigashi (1873-1937), born in Ehime prefecture, was a Japanese Haiku poet. He started to compose Haiku at the age of sixteen, inspired by the highly renowned Haiku poet Shiki Masaoka. He later became absorbed in free style Haiku and co-founded the avant-garde Haiku journal So-un.
