Jigoro Kano

He founder of modern judo, once invited Gichin Funakoshi and a friend, Makoto Gima, to perform at the Kodokan (then located at Tomisaka). Approximately a hundred people watched the performance. 

Gima, who had studied under Yabu Kentsu as a youth in Okinawa, performed the Naihanshi shodan, and Funakoshi performed the koshokun (kushanku dai).

Jigoro Kano sensei watched the performance and asked Gichin Funakoshi about the techniques involved. He was greatly impressed. He invited 

Funakoshi and Gima to a tendon (fish and rice) dinner, during which he sang and made jokes to put Funakoshi at ease. Funakoshi insisted on hito-kata sanen (three years on one kata).
