When at Naha Air Base we would do uchikomi in place where Uke would start off without much resistance and then increase it after awhile. Tori would do a bunch of right side, then left side of whatever technique sensei suggested (most sensei there hardly ever spoke, just nod and grunted) and we never spoke, but grunted or kiai. After awhile Uke world begin to move about, mostly in a circular manner, and Tori would do a bunch of techniques in step while moving about. After that Tori would begin to switch from left to right, depending on the technique, and it would end up being a one sided randori where Uke increased resistance; and stiff arming Tori, so after Tori and Uke were beginning to really sweat – Uke and Tori would switch places and repeat that sequence.
After each had enough of that and were hot and sweaty, nearly exhausted – then free style randori would commence. Usually followed by sensei showing us how bad we were, correcting and so on. In those days, practice was serious business, we would go for hours. You see, the only real way to develop techniques from uchikomi is to be bone tired then hard randori. At least that was the way it was then.
Weekends we would go downtown to the Police Dojo where all the mudansha would clean up, wash windows and make sure the ‘ka mizu’ had ‘mizu’ for the ‘mizu ka.’ You use; we did not get water during practice; only sensei did.
Uchikomi began with in a static or stationary manner and evolved into a dynamic manner where Uke would start off easy and increase stiffness, resistance and usually stiff arming Tori; so Tori had to learn the workarounds. We always did right then left techniques and subsequently many of began favoring left side because most Judoka who never trained over there were taken aback by it. Uchikomi done correctly is a great training tool. But, I left the Far East as a wiry, skinny 22 year-old black belt that could shiai like hell, but teaching was never considered. It was sad in a way that we had so few sensei to learn from and that we probably taught some not so good Judo and uchikomi practice.
There were some really good sensei scattered about the country; some Judo got organized, along with the usual Judo politics, that we just ignored as much as possible. Out of it some sensei would travel around or we would seek them out, train and continue learning. Very important part of Judo is learning. Many of us got really stagnant and after decades of that some of us walked away from it too early in the career. I suspect, just IMHO, that if things had been different our Judo would have turned out to be more popular here.
