Hector,
Take a look at that pic I uploaded with Kurosaki and a couple other guys including Fujiwara kicking that tire. Kurosaki was known as the "Devil" and Mejiro Gym was the "Hell Dojo". The training conditions at Mejiro were to be simply put "inhumanly brutal". Hours of bag and pad work, tire kicking, running and shadow boxing, etc. made Kurosaki's fighters to be tough and skilled. There's a documentary called "36 Years of Silence" about the 1964 challenge between Kyokushin and Muay Thai. You can find it on Yahoo!Japan auctions. It's mostly about went on behind the scenes before Kenji Kurosaki, Tadashi Nakamura, and Akio Fujihira went to Thailand and it also shows Fujihira's fight against Howfai Lukwantang. The film shows the hardcore training that was at Oyama Dojo (Sosai's school for Kyokushin back then) and some of the preparation against the Nak Muays. It shows Akio Fujihira and Tadashi Nakamura putting on gloves and sparring. Here's a brief clip of some of the scenes in the documentary.

As you can see, Kurosaki was a very hard-working and dedicated karateka. The foundation of Kyokushin helped Kurosaki to form his Mejiro Gym into a respected force.

Wow, you got a lot of vintage footage. I'll get back to you about this.
