How was the Flexcushion Born?

Derived from MATAWARI Stretch of Japan's Martial Art “Sumo”

Nao Sakata(1993)
Nao Sakata
Our President & Founder, Nao SAKATA, when he was a member of the Sumo Team at Rikkyo University, had difficulty with Sumo's MATAWARI (splits) training, which was essential for Sumo. Later, he found it easier to stretch when he sat on the Dohyo, a straw bag (5cm / 2 inches high), which is now the front height of the Flexcushion. With advice from Professor Hideo NUMAZAWA (Rikkyo University), Nao SAKATA developed the Flexcushion.
