Japan's cycling infrastructure is among the best in Asia — dedicated cycling paths, excellent bike rental networks, convenience stores every 20km, and scenery that shifts dramatically with each island or mountain pass. These are the best routes for a cycling holiday.
Shimanami Kaido: Japan's Greatest Cycling Route
The Shimanami Kaido connects Onomichi (Hiroshima Prefecture) to Imabari (Ehime, Shikoku) across six islands via suspension bridges, covering 70km total. The dedicated cycling path never shares lanes with cars; blue lines painted on road surfaces guide you across each bridge and through each island. The route passes citrus groves, ancient temples, and small fishing villages with sea views throughout. It can be ridden in one hard day (6–8 hours), comfortably in two days with an overnight on Oshima or Omishima island.
Rental bikes available at both ends (Giant Store Onomichi, ¥3,000/day for road bike; return at Imabari or other points). The Sunrise Itoyama hotel in Imabari rents and services high-quality road bikes and provides route guides in English.
Lake Biwa: Japan's Largest Lake
Lake Biwa in Shiga Prefecture (near Kyoto) has a dedicated cycling path (Biwako Cycling Road) circumnavigating Japan's largest freshwater lake — 235km in total, usually done in 2–3 days. The northern lake shore is quiet and rural; the southern section passes through Otsu city. This is the classic Japanese "bike packing" route, with cycling hotels (cyclist-specific accommodation with bike storage and repair facilities) positioned roughly every 50km.
Hokkaido: Open Road Cycling
Hokkaido's wide roads, minimal traffic, and dramatic pastoral scenery — flower fields, dairy farms, volcanic mountains — make it Japan's most epic open-road cycling destination. The Biei-Furano area (flower fields, patchwork hills) and the Shiretoko Peninsula (UNESCO wilderness, bears) are the most iconic Hokkaido routes. Rent bikes in Sapporo or Asahikawa; support luggage forwarding via takuhaibin to each night's accommodation.
Tokyo: Urban Cycling
Tokyo is surprisingly cyclable for a megacity — the Sumida River cycling path, the Imperial Palace circuit (5km, popular at dawn), and the residential back streets of Yanaka and Koenji reward a day of urban cycling. Docomo Bike Share operates throughout the city (¥165/30 min). The main cycling challenge: hills in western Tokyo and the sheer scale of the city.
Practical Essentials
Helmets are required by law for children and strongly recommended for adults. Japanese law prohibits cycling while holding an umbrella or using a phone. Cycling on footpaths (except where signed) is technically illegal. Most convenience stores stock basic repair supplies. The Komoot app has good Japan cycling route data; Strava Japan community provides route recommendations.
