Katsuura

Katsuura, Japan
🌀Strong rips

Katsuura sits at the southern end of Chiba's surf coast, rewarding those who venture farther from Tokyo with beautiful waves and significantly fewer crowds. The beachbreak produces quality peaks during typhoon swells, and the fishing town atmosphere includes some of the best seafood on the coast. The extra distance filters out the weekend warriors, leaving more waves for those who make the trip.
