Onjuku Beach

Onjuku, Japan
🌀Strong rips

Onjuku is Chiba's mellow alternative to the competitive intensity of Tsurigasaki. This family-friendly beach town offers gentle waves that are perfect for beginners and longboarders, with a relaxed atmosphere featuring seafood restaurants and small guesthouses. The wave is forgiving, the local vibe is welcoming, and the train access from Tokyo makes it an easy day trip. When typhoon swells hit, even Onjuku can produce surprisingly fun walls.
