Hasaki (Kamisu)

Hasaki (Kamisu) is a large, sandy Pacific-facing beach with generally clean water and small-to-medium wave conditions. The launch area is described as very wide, making it practical for kitesurfing in particular, and the surf is characterized as an exposed beach break that can produce good-quality waves when swell and sandbar conditions line up. For kitesurfing, the most useful wind sectors are from northerly through northwesterly directions (including N, NNE, NE, NW, and NNW). Typical riding wind is described in the range of roughly 12–25 knots, with light gustiness noted. Kitesurfers commonly use sizes around 9–12 m² (with smaller sizes mentioned for stronger frontal passages), and the spot is generally rated as intermediate-level suitable. Safety considerations are important: large breakwater structures (moles) and tetrapods are positioned along the beach, and there are also notes about currents and fishing lines. During the summer bathing season (July to August), kitesurfing and windsurfing are typically restricted to zones outside designated swimming areas, so riders should plan launches and tracks accordingly and keep a clear buffer from the hazard features. Seasonally, the spot is often described as best in spring and autumn, with comfortable temperatures and improved wind consistency. Summer can also bring afternoon sea-breeze development, and water temperature is reported to rise from mid-teens °C in winter to the mid/upper-20s °C by late summer. Weekend and holiday crowding can be noticeable, while weekdays are often calmer.
