Isao Okano instructor

Who was Isao Okano instructor

I don't know if true, but once I read Isao Okano was a student of Kenshiro Abbe.

I suspect that the reason why his coaches are not listed is the gaffe with colored judogi which meant he was not considered someone to be associated with.

This I doubt is correct. Kenshiro Abbe was in the UK from 1955 onwards for many years, and prior to that he taught in the Kyoto area. Okano-sensei was only born in 1944 and grew up in Ibaraki Prefecture.

In his book "Vital judo : Grappling techniques" Okano Isao (1944 - ), Tokyo, Japan, Japan Publications, 1976, 192p, ISBN 0870405179 in preface p. 6, he credits Kyoto police force instructor Hosotani Fumio for "greatly influencing my grappling techniques".  Whether he counts as his "instructor" is doubtful as he credits also Tomiki Kenji for encouraging study of new attacks and Okuda Yoshiro for "receiving much simulation in grappling techniques".

Whole passage
"In the study leading to the production of Vital Judo: grappling techniques, I have enjoyed the inspiration and assistance of many people. My own grappling techniques have been greatly influenced by professor Fumio Hosotani, who is currently a judo instructor with the Kyoto police force. I received much stimulation in this aspect of judo from the outstanding judo expert Yoshiro Okuda. Professor Kenji Tomiki did much to encourage me in the hope of pioneering new kinds of initial attacks. In addition, I should like to express my gratitude to the following judo men, who gave unstintingly of their assistance in the production of this book: Katsuji Seki, Shinobu Sekine, Nobuyoshi Sato, Kazuhiro Ninomiya, Hisashi Tsuzawa, Takafumi Ueguchi, Masami Kina, Hidehiko Asanuma, Shozo Fujii, Yoshimi Hara, Koji Kuramoto, Takao Kawaguchi, Yoshiharu Minami, Katsuhiko Kashiwazaki and Kyosuke Sahara."
