In addition to the Miltary Police, the Japanese Coast Guard also have their own Taiho-jutsu training (based on the police system). I recently obtained the following two manuals.
Taiho-jutsu Kunren no Tebiki’ (逮捕術訓練の手引き - Arrest Technique Training Guide)
Kihon-hen (基本編 - basic / foundation volume)
First Edition, published in 1997 by the: 'Kaijōhoanchō Keibi Daiikka'
(海上保安庁警備第一課 - Japan Coast Guard First Security Division)
'Taiho-jutsu Kunren no Tebiki"
(逮捕術訓練の手引き - Arrest Technique Training Guide
'Ōyō-hen'
(応用編 - applications volume)
First Edition, 5th printing, published in 2007 by the 'Kaijōhoanchō Keiji-ka' (海上保安庁刑事課 - Japan Coast Guard Criminal Affairs Division)
They are very interesting - more to follow regarding these in future posts.
