About this spot
Aga Town Mikawa B&G Marine Center Pool (阿賀町三川B&G海洋センタープール) is an outdoor pool at the Mikawa B&G Marine Center in Aga Town, Higashikanbara District. It typically opens from late July to mid-August and consists of a main pool (25m x 6 lanes) and a toddler pool (6m x 10m). With plenty of lanes, it rarely gets crowded, so kids who want to practice swimming can go at their own pace. The toddler pool is sectioned off separately, so families can let little ones play in the water with peace of mind. Located in a mountain town along the valley of the Agano River, the air here feels cooler than in the city, making it comfortable to visit even in the height of summer. Free of the crowds you'd find at a resort-style facility, you can swim leisurely alongside local children.

Tips
The opening period, hours, and fees can change from year to year, so always check Aga Town's official information beforehand. Being an outdoor pool, it may close suddenly due to thunderstorm warnings or bad weather. Shade is limited, so a picnic sheet and a hat are essential. There are few shops nearby, so it's a good idea to buy drinks and snacks at the roadside station beforehand. Temperatures cool down in the mountains from evening onward, so having something to put on after getting out of the water will help you stay warm.
Best time to visit
About 3 hours 10 minutes. In the afternoon, the sunlight softens and the breeze through the valley feels pleasant.
