A national windsurfing playground

For all the swimming, the real reason Murakushi gets visitors year-round is the wind. Hamamatsu's beach and marine-sports council calls this corner of the lake a nationally rare stretch where the terrain, climate and breeze all line up, and the shallow water is exactly what makes it safe and easy to learn: when the wind blows, Lake Hamana stays flat and chop-free instead of building swell, and riders can't be swept out to open water. The wide, clean shallows are a favorite training ground for beginners, and there are enough sailing and windsurfing shops nearby—including WIND VILLAGE in Murakushi-cho—to keep the boards on the lake across the whole year, not just summer.↗↗↗

Wading, clam-digging and fishing

The same shallow flats that make it good for sailing make it good for hunting things. As the tide pulls back you can dig for shellfish while you swim, and the area is known for the kind of easy, catch-what's-there fishing (五目釣り) that draws people on a relaxed afternoon—whiting, goby, halfbeak, flathead and black porgy are all on offer. Anglers keep coming through the cooler months too: Murakushi's broad shallows butt up against the lake's deep ship channel, so the spot produces everything from summer topwater black bream to prized winter flounder, with a tackle shop just down the road. Be aware that the water here is not the crystal-clear ocean kind, with some algae along the edge, so it is judged a windsurfing and clam-digging beach first and a pure swimming beach second.↗↗↗↗

Planning your visit

The official swimming season runs roughly from mid-July to the end of August, when beach-side facilities and lifeguards are around and the lawn fills with families. Outside those dates the same waterfront simply becomes a windsurfing, fishing and strolling spot, often at its most peaceful. Facilities are deliberately basic: there are clean public toilets and free lakeside public parking, but generally no showers and limited changing space, so a towel and a change of clothes in the car are wise. Getting here is easy enough on a day trip from Hamamatsu—about 10 minutes' walk from the Murakushi-Kaigan bus stop, or some 30 minutes by car from Hamamatsu-nishi IC via the Kanzanji–Murakushi toll road; if you are already around the Kanzanji hot-spring district on the lake's west side, you are only about 15 minutes south.↗↗↗↗↗

If you want to stay by the water rather than pass through, there is a small lakeside campfield just along the shore in Murakushi-cho whose sites reach right down to the lagoon's edge—handy for combining sunset views, SUP or kayak paddling and a lakeside drink into an overnight.↗
