There's a fine variety of routes and different themes offered here to suit everyone from casual pedallers to more serious cyclists. The English-speaking staff and guides are very friendly and professional. You can also rent bikes from ¥2500 a day.

The same company also offers excellent kayaking tours (the longest route takes you on a fascinating 10km circuit including the Sumida, Kanda and Nihombashi Rivers) and running tours around the palace and along the Sumida-gawa.
