Machino Rivermouth
Machino Rivermouth sits on the exposed Noto Peninsula of Ishikawa Prefecture, jutting out into the Sea of Japan to catch maximum swell from Siberian winter storms. When northwest winds howl down from the continent, this rivermouth lights up with powerful peaks—some of the biggest barrels Japan has to offer. The remote location means empty lineups, but also cold water, limited facilities, and serious commitment. This is frontier surfing for those who earn their waves.
