Tsukui is a beach break located on the southern coast of Kanagawa Prefecture, Japan, facing south toward open water. The spot features a sandy beach with gradual shallow water conditions, backed by residential and agricultural areas. This is a light-wind location suitable primarily for beginners and those practicing flat-water skills rather than wave riding. The average wind of 8.5 knots is marginal for kitesurfing, and with only 13.6% reliability, consistent sessions are rare. Wave conditions are minimal at 0.81m average, making this spot better for kite control practice than progression. East winds (90°) provide the most consistent side-shore approach. The relatively protected bay setting and shallow water mean this spot is safer for learning than more exposed coastal areas, though the combination of weak and unreliable wind makes it challenging for building skills. Best suited for flatland freestyle practice or very light-wind days when other locations are unrideable. Summer months may offer slightly better conditions.
