What are the need-to-knows about cycling in Japan?

In Japan, cyclists ride on the left-hand side of the road. Helmets are strongly recommended, and road rules are strictly observed. Rural traffic is light, but climbs can be sustained and steady. Convenience stores are frequent and well-stocked, making hydration stops easy. Respect for local customs, punctuality and quiet road behaviour are appreciated. Guided and supported cycling tours in Japan provide the safest and most seamless experience.
