I'll be in Tokyo next week. I've already walked Route 246 twice. Once here and once here. I've also put a blog entry about it here. If I have time and the weather cooperates I might go over there again and take a walk around the old course. It's in a very nice area of Tokyo and much of it is closed off to traffic on Sundays. If I take pictures this time I plan to concentrate on the corners where all of the key time is lost or gained.
