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.

Frequently Asked Questions

What kind of wave is Onjuku Beach?

Onjuku Beach is a beach break in Onjuku, Japan, with peaks that run both left and right.

What swell works best at Onjuku Beach?

Onjuku Beach picks up swell from the E round to the SSE, and it's best when it's coming straight out of the E. It starts working at around 0.5m and handles up to about 2m, with the sweet spot around 1.2 to 1.6m. Period matters too: aim for 11s or longer, as anything under 7s tends to be weak. These are the numbers our scoring uses, so treat them as a guide rather than a promise.

What wind is offshore at Onjuku Beach?

A W wind is dead offshore at Onjuku Beach, and anything from the SW round to the NW keeps it clean. The morning is typically the best window, roughly 5am to 10am. Light winds from other directions can still be fine; strong offshores can make it hard to get into waves.
