About this site
On January 3, 2026, I rode out to the Fuji Speedway kart course figuring, 'It's the dead of winter on New Year's holiday, the place will basically be mine.' Nope. It was total chaos — something like 100 bikes crammed onto it. Even with riders split into skill classes, there were still about 40 bikes at a time fighting for space on a track that's only 800 meters long. Naturally, people were dropping their bikes left and right. It was, frankly, gross. I built this site so nobody else has to live through that again.
