Enjoyable Year-Round

The Seto Inland Sea region, where the Shimanami Kaido is located, has a mild climate with relatively little rainfall compared to other parts of Japan. This makes it an excellent area for outdoor activities like cycling. You’ll see cyclists on the route throughout the year. Even in winter, snow is extremely rare, and with proper clothing, cycling can be just as enjoyable. Many locals ride all year round.

Seasonal Charms

One of the joys of visiting Shimanami Kaido is experiencing the changing scenery and local foods across the seasons. You’ll see the islands shift from fresh greenery to colorful autumn leaves. Seafood and farm products also vary by season. Citrus fruits like mikan (mandarins) and lemons—famous in this region—are typically in season during winter. Though winter sees fewer visitors and shorter daylight hours, the cool temperatures are actually ideal for long-distance aerobic exercise, much like marathon running.

When the Weather is Ideal

If you’re looking for the most comfortable weather for your cycling trip, aim for April to May in spring or October to November in autumn. These months are pleasantly warm—not too hot, not too cold—and rainfall is limited. In spring, depending on timing, you may catch cherry blossoms, and the fresh green scenery looks vivid against the blue sea. Autumn’s best season is from late summer to just before the autumn leaves change. Apart from major holidays like Golden Week, autumn tends to be the busiest time for cycling visitors.
