As an informant of the Shodon dialect, he also worked with linguists Yukio Uemura, Shirō Hattori and Samuel E. Martin.
He published his folkloristic work at the Nantō (Southern Islands) edited by Eikichi Kazari, and the Tabi to Densetsu (Travels and Legends).
He won fame for his paper Amori Onagu (天降り女人) (1943), where he proposed a couple of novel theories on Amami's swan maiden motif, a conundrum originally posed by Shomu Nobori.
His main source of information was a group of young men from Amami who had been drafted into the armament industry in Nagasaki.
He ran a private-tutoring school for the English language during daytime while continuing folkloristic and linguistic research at night.
