2026 Miyagase Lake Cool Stroll: A Full-Day Course

Spend a day enjoying the cool breeze off the water at Lake Miyagase (宮ヶ瀬湖), one of the greater Tokyo area's leading dam lakes. Surrounded by the Tanzawa mountains, Lake Miyagase offers a beautiful contrast between its blue surface and the green mountains, with spacious lakeside parkland and the Mizu-no-Sato Suspension Bridge (水の郷大つり橋), while the breeze crossing the lake feels wonderful. Even in September and October, when the lowlands are still hot, this mountain lakeside stays comfortably cool. The lakeside Konakazawa Parking Lot (小中沢駐車場) charges 300 yen for up to 2 hours and 500 yen beyond that (900 yen during special periods) for regular cars, and 1,500 yen for large vehicles. This course stops at the free-admission Hattori Farm (服部牧場) and the Miyagase Dam Water and Energy Museum (宮ヶ瀬ダム水とエネルギー館), where you can learn how the dam works in a fun way, in the morning, then spend the hot afternoon hours relaxing in the breeze by the lake.
