2026 Full-Day Course: Aga Town Mikawa B&G Marine Center Pool

This full-day course centers on Aga Town Mikawa B&G Marine Center Pool (阿賀町三川B&G海洋センタープール) in Aga Town, Higashikanbara District, which typically opens from late July to mid-August. Outdoors, it features a main pool (25m x 6 lanes) and a toddler pool (6m x 10m), so both kids who want to swim seriously and those just starting out with water play can spend time in the same place. Aga Town, where the venue is located, is a mountain town with settlements scattered along the deep valley carved by the Agano River (阿賀野川). The air here is cooler than in the city, which is a real bonus in summer. In the morning, start at Michi-no-Eki Aga no Sato (道の駅阿賀の里), a roadside station built on the banks of the Agano River, where you can take a boat cruise through the gorge or browse a market stocked with local specialty goods. Next, stop by the hot-spring town of Mikawa Onsen (三川温泉) and pause for a breather in this quiet mountain hot-spring village. After lunch, move on to Aga Town Mikawa B&G Marine Center Pool and enjoy a full afternoon of water play. It's also well connected via the Bandai-Etsu Expressway, making it a comfortable day-trip distance from the Niigata City area.
