Cyclocross

There is an active cyclocross scene in Japan which includes the Shonan Cyclocross Series and other races in the Tokyo area. In the lower categories, you can ride any kind of bike, including a mountain bike. Since modern road bikes take fatter tyres, you can do races on your regular road bike. For the higher elite categories, rules include maximum tyre width of 33 mm. 

1. AJOCC Race Calendar

The Association Japanaise des Organisateurs de CycloCross has an excellent calendar of races with links to entry websites.

2. Spoen Cycle

Lists some cyclocross races, as well as other events, such as MTB races.

3. Cyclocross Practice Tracks

There are two cyclocross practice tracks by the Tama River. They are both about 2 km with many twists and turns. Furuichiba is on a flat, grassy area; Inagi runs through tall grasses on bumpy, sandy soil.  Cross Coffee, a well-known cycle cafe, is nearby.
