I translated historical articles about Okinawan karate written in Japanese into English. Also enjoy my videoclips of Kata of Okinawan Goju-Ryu Karate and Ryukyu Kobudo. My e-mail address: firstname.lastname@example.org
Sorry but in fact no ninja in Osaka Castle now. The building behind me is a part of Osaka Castle. It is a turret called "Rokuban Yagura" in Japanese. Unfortunately you cannot see the castle tower in the video, so I pu the photo.
