Bloodyelbow did an excellent Karl Gotch tribute week a while back, some great history reading here if anyones interested
Kinda apt that site did it since his legacy arguably looms larger more over MMA (especially in japan) than wrestling these days.
This is his debut match in Japan (1961), not hugely exciting but very interesting in that it can be looked at as the big bang which to led Japanese shoot/strong style as well as evenutally Japanese MMA, 10 years later he'd be back in Japan putting over a young Inoki.
It also really needs mentioning how many future legends he trained in Japan. Fujinami, Matsuda, Sayama and Fujiwara just to name a few.
