Yashimagahara Marshland is a high-moor located at an altitude of approximately 1,632m in Kiryu-ga-mine, central Nagano Prefecture. As the southernmost high-moor in Japan, it boasts an 8.05m-thick peat layer formed over 12,000 years. The marshland is home to diverse alpine plants, including sphagnum moss and cotton grass, with vibrant displays of day lilies (nikkoukisuge) and Japanese fire lilies (renge-tsutsuji) particularly stunning during the summer. Well-maintained boardwalks allow for leisurely exploration of this natural wonder. Surrounding mountains like Kurumayama and Yashima offer further opportunities for hiking and trekking. Yashimagahara Marshland is a sanctuary of nature, offering a rejuvenating experience with stunning views, delicate flowers, and fresh mountain air. Experience its unique charm for yourself!
