Japan: Chiba & Shonan
Japan's biggest surf population lives here because it's the only coast within day-trip range of Tokyo: Chiba's Pacific-facing beaches (Ichinomiya/Tsurigasaki, the 2020 Olympic venue, plus Taito) and Shonan's Kanagawa beaches (Kugenuma, 50 minutes from Shibuya) both ride the same August–October typhoon swell window, with smaller, crowded summer surf the rest of the year.
Surfing in Japan: Chiba & Shonan, month by month
Why Chiba & Shonan
This is the coast that made Japan an Olympic surf host, not because the waves are world-class but because millions of people live within reach of them. Ichinomiya's Tsurigasaki Surfing Beach (the Shidashita peak specifically) hosted the 2020 Tokyo Olympics surfing competition. Shonan, closer to Tokyo along the Kanagawa coast, is the country's busiest learn-to-surf beach strip — Kugenuma Kaigan is a short train ride from Shibuya and correspondingly crowded.
When to go
- Aug–Oct: typhoon season. This is when the beach breaks here actually have size and shape; also hurricane season, so conditions can turn dangerous fast and local advisories matter.
- Nov–Apr: small winter NE windswell, cold water, a wetsuit (often 4/3 or thicker) needed.
- Rest of year: mostly flat to ankle-high; the lineup is still busy regardless of swell.
Who it suits
Beginners based in Tokyo who want an easy day trip, and anyone curious to surf the actual Olympic beach. Not a trip-worthy destination on its own for a travelling surfer looking for quality waves — go for the novelty and the access, not for the surf.
