You can get a good idea of where Yamagata is by looking at the above link.
I'll be sure to tell everyone about it the competition:O). When are you coming back to Nippon??
Last weekend, the last competition of the Japan's kayak season, the Christmas Cup, was held. Playboaters, creekers and slalom kayakers participated in the downriver race in Mitake. Good times all around. I'll post the picture link in a week or two.
Stay tuned next week for a surf upate from Chiba, Japan...
