More lines than facts here!
Hi Rick.
Tanaka-S. claims a slightly different line from those claimed by either Hatsumi-S. or Tanemura Sensei, although the lines were the same up until Ishitani (Ishiya) Matsutaro Sensei, who taught Takamatsu Sensei among others including Kakuno Hachiheita Masayoshi-S. The line of Kukishin Ryu that Tanaka-S claims leads through Kakuno-S to Minaki Saburoji Masanori and then to Matsuda Kyodo who left it to Tanaka Fumon.
The lines after/during Takamatsu Sensei's lifetime are very confusing but it can help to look closely at Japanese sources rather than rely on English ones...Good places to start are the Ueno Sensei Memorial booklet (and translation in English) that has both Tanemura Sensei and Tanaka Fumon mentioned in it and also possibly Serge Mol's recent Jujutsu book as it also lists Tanaka Fumon's line of Kukishin Ryu and you can see better where the splits occurred. You may be able to get the Ueno Sensei memorial still from www.buyubooks.com although they sold fast!
As mentioned above the other schools have Tanaka-S listed as Soke Dairi and not as Soke and they all came through Kaminaga Shigemi, (Right? The info I have here is not entirely up to date on these schools...They end with Kaminaga-S) another of Ueno Takashi Sensei's students....
Tanaka Fumon is also listed in the 'Nihon Kobudo Soran' as the head (Soke) of the Kukishin Ryu after Minaki Saburoji as of Heisei 9 anyway (Around 1998 I believe) and is listed under 'other Martial Arts' so at least at that time he was 'officially recognised by the Nihon Kobudo Kyokai who published the book....
The maze is very long, and confusing also...Even in English.
Hope that helps some?
Regards.
