Looking for background information on Chonan Kata (Eldest Son?). It was supposed to have been a kata passed on from Kitagawa, a student of Matsumura of Shorin Ryu. In description it is liked a stripped down simplified version of Naihanchi Kata, which it is said to be a predecessor of. Also looking for information on two other kata called San Jin (?) and Ien Hou (?), also said to come from Kitagawa. San Jin (3 Arrows, 3 Battles?) is a tension kata and very much like Sanchin but again very stripped down and simplified. Ien Hou (?) is a larger version of San Jin and contains arm circling with tension. All three kata were said to be taught to Kitagawa by Matsumura and have a bit of White Crane flavor to them. Kitagawa taught Shintani Masaru. Shintani passed these on to my teacher. Anymore information anyone has on these kata would be much appreciated, especially translations (with kanji). All three kata definitely belong to the same style and follow a similar theory and progression of Fujian White Crane. In case if anyone is wondering, yes I did talk with a few Wado Kai people but they had no more information than what I have presented.
