5 hrs or more from (Hatomachi Pass) will take you to Ayamedaira.
Ayamedaira Marsh is covering a broad, gradual ridge on the south side of Ozegahara Plateau. Because of the high altitude, snow melts slowly and flowers bloom intensely for short periods of time. The colonies of Narthecium asiaticum that bloom in July and August are especially spectacular, creating what can truly be called a "Heavenly Paradise".
