Evidently, Higashionna became interested in furthering his study of Te and around the age of 23 - 24 he travelled to Fuchou China. Oral testimony maintains that Higashionna’s teacher in Fuchou was Ryuru Ko. Ryuru Ko was a master of White Crane Gongfu who reportedly made wicker baskets for a living.
What Higashionna actually learnt from Ryuru Ko whilst he was in China remains a point of much interest. The most common account is that Higashionna learnt the entire syllabus of classical Goju Ryu Kata, Sanchin, Saifa, Seiunchin, Shisochin, Sanseiru, Seipai, Kururunfa, Seisan and Suparinpei. Despite this we do not know for sure, and evidence exists to suggest that Higashionna’s original system of Nahate may have comprised of only Sanchin, Sanseiru, Seisan and Suparinpei.
Another point of much debate is how long Higashionna actually spent in China. The common version is that Higashionna spent approximately 10 years training with Ryuru Ko, but his exact date of return to Okinawa is unknown.
Upon his return to Okinawa Higashionna returned to his families firewood business, but his reputation as a skilful practitioner spread throughout Naha, earning him the nickname ashi no To’onna (legs To’onna) due to his excellent kicking ability.
As a result of this Higashionna began teaching his system on Nahate to a few carefully selected students, notably Kiyoda Juhatsu Sensei the founder of To’on Ryu, and his kohai Miyagi Chojun Sensei the founder of Goju Ryu.
