Defunct Defunct Shinobu Orikuchi (折口 信夫, Orikuchi Shinobu, 11 February 1887–3 September 1953), also known as Chōkū Shaku (釋 迢空, Shaku Chōkū), was a Japanese ethnologist, linguist, folklorist, novelist, and poet.

In 1925, he published Between the Sea and the Mountains (海山の間, Umi Yama no Aida), his first tanka book, which is highly esteemed.

As a folklorist, Yanagita was known for rejecting every sexual subject; Orikuchi, in contrast, was very open-minded to these matters.

He became a model for the protagonist in Mishima's short story Mikumano Mōde (三熊野詣), while his novel Shisha no Sho was the basis for a film by Kihachiro Kawamoto.

Harumi Orikuchi (折口春洋), scholar of Japanese literature and poet, was his de facto partner.
