About
Oshima (Sakai) is a rocky left-hand point break on Oshima Island near the Tojinbo area in Fukui. The wave is described as a regional classic, but it is extremely inconsistent—reported as rarely breaking, around five days per year. When conditions align, it can hold meaningful swell (working around 1.5–2m+) and deliver short rides that can extend to longer sessions on exceptional days. Because the bottom is boulder-strewn with large rocks and sharp areas, the spot is not forgiving. Providers consistently describe difficult entry and exit and potential strong currents during bigger swell, so the practical risk level is high. The wave is also exposed, meaning you should expect conditions to change quickly with wind/swell direction and strength. Wind needs to cooperate for cleaner water. One provider notes East or Northeast winds can help produce cleaner offshore conditions, while another describes the wind as frontal and notes very low overall reliability (matching the spot’s “rarely breaks” character). Sessions are therefore best treated as forecast-driven—plan around substantial winter swell and check updates before traveling. Crowds tend to reflect the spot’s rarity: few surfers on weekdays and more people on weekends when it does break. Local surf etiquette is emphasized and localism is described as possible/more likely when the spot is active.
