Niyodo is a surf spot located in Japan known for its river mouth breaks. This spot can be a bit hit or miss, with the right-hand waves often providing better rides than the left. On those rare good days, surfers might find multiple barrels rolling over cobble-studded sandbars. The place is influenced by local rainfall and the number of typhoons that come through, so conditions can change quickly.

The waves here break primarily on south swells, with optimal conditions coming from the southeast or southwest. It can handle swell sizes of around 4 feet (about 1.2 meters), offering both left and right waves. Mid to high tides are the best times to surf, especially when the wind is coming from the northwest. However, this spot is not for everyone; it’s an expert-only wave, as it can pack quite a punch and has strong rips that can challenge even skilled surfers.

Niyodo tends to get crowded on smaller days and weekends, which might introduce some localism. When the waves are big, you’ll see more spectators than surfers, and only those with solid skills tend to take on the powerful waves here. If you’re planning to surf Niyodo, be prepared for the crowd and know that you might need to wait for the right conditions.
