- Japanese: 仲原善忠 (Nakahara Zenchuu)
Nakahara Zenchû was an Okinawan scholar, known particularly for his work on the Omoro sôshi, a written collection of songs and poems which constitute an oral history of Okinawa and the Kingdom of Ryûkyû.
Nakahara was born in Nakazato magiri, on Kumejima. He attended the Okinawa Normal School, and Hiroshima Normal High School, before going on to teach at various schools in Tokyo, Shizuoka prefecture, and elsewhere.
He first began research into Okinawan history around the age of 50. After the end of World War II, he researched the native Ryukyuan religion, and produced a paper which drew great praise from Yanagita Kunio, widely regarded today as the father of Japanese ethnology (minzokugaku). He would go on to produce a number more papers on topics relating to Okinawan history, omoro, and ethnology, as well as a middle school textbook entitled "History of Ryukyu" (琉球の歴史, ryûkyû no rekishi).
