If you have any evidence that this is just a claim from Kunihiko Tosa shihan without any relevance to facts then please present it But until then the books of Kunihiko Tosa shihan Genseiryu Karatedo Kyohan  with written history of Genseiryu and preface by the founder Seiken Shukumine the agreed statements by Hiromichi Kohata of Spain Takahashi of Ryounkai etc stands as legitimate claims They all state that Kunihiko Tosa was the first direct student of Seiken Shukumine You changing the article of Genseiryu in this way may only be because you want to start yet another revert war Instead I encourage you to get your facts and sources straight before messing facts up or again only offering your lies and deceit with your edits
