Oniguchi

Oniguchi is a hidden-access beach break near Minamikyushu that can deliver clean right and left waves when the swell window lines up. The spot is described as often “sometimes breaking,” with sessions best on low and mid tide (also workable around low/mid stages on rising or falling tide). Wave size can start working under 1 m and hold up to around 2 m or more, with wave quality generally reported as good. On better days, normal ride lengths are typically short (< 50 m), while strong sessions can extend to roughly 50–150 m. Waves are commonly described as hollow and fun, with both directions available. Wind is typically from the east to northeast, and those directions are reported to groom the waves for a cleaner ride. Typical wind strengths are around 10–20 knots, but overall wind reliability is listed as low, so conditions can vary between attempts. Mild sea-breeze effects may appear in summer afternoons, though the spot’s more favorable months for wind are reported as September through December. Access is the main challenge: the beach entry is concealed via hidden access paths and may involve a short walk from where you park. Because reef sections and scattered rocks are a stated hazard near the shoreline—and stronger currents can occur with larger swells—plan for careful approach and use a GPS to reduce the risk of missed/unsafe access points.
