Japan: Okinawa
Japan's one genuinely subtropical surf coast: warm water year-round and a coral reef break, Sunabe, right off a seawall in Chatan that's one of Okinawa's most popular and accessible waves. Typhoon season runs earlier and longer here (June–October) than mainland Japan.
Surfing in Japan: Okinawa, month by month
Why Okinawa
Okinawa surfs differently from the rest of Japan: warm water all year, coral reef rather than sand-beach breaks, and a typhoon season that starts earlier and runs longer (June through October) than the mainland's August–October window. Sunabe, a reef break right off the seawall in Chatan, is the main-island benchmark — intermediate-to-advanced, shallow at low tide, and busy with a local scene.
When to go
- Jun–Oct: typhoon season — the only time there's consistent size. Watch local typhoon tracking; conditions can turn dangerous quickly.
- Mid-to-high tide: Sunabe's reef is too shallow to be safely surfable at low tide.
- Nov–May: mostly flat.
Who it suits
Intermediate-to-advanced surfers comfortable on a reef, and reef boots are a sensible precaution regardless of level. Not a beginner destination on this particular break.
