Yoshimoto eventually joined the Jufuku-ji, taking the Buddhist name Nen Ami (念阿弥?), Jion (慈恩?), before traveling to teach in Okinawa. Today, many traditional schools of karate, including Shotokan, practice a kata named "Jion" after him. Yoshimoto is also frequently credited with founding the martial art of Isshin-ryū kusarigamajutsu, but this may not be literally true. Some historians believe that Tan Isshin (c.17th century), who may have studied Maniwa Nen-ryū with Yui Shōsetsu (1605–1651), was the true founder of Isshin-ryū kusarigamajutsu. They believe that he was inspired by Yoshimoto's teachings and chose to credit him as the founder of the art to honor him.
