A Hydrangea-Filled Mountain with History

Hosted on Mount Minamisawa, this mountain is said to be where Chuichi Minamisawa, who once lived in this area, began planting hydrangeas along the path to his parents’ grave. Continuing to plant them for 50 years, today there are over 15,000 hydrangeas blooming on the mountain.

There are over 50 different varieties of hydrangeas here, including some rare types that are scarcely seen even within Japan. Surrounded by tall trees, the area becomes enveloped in a magical atmosphere for about a month starting in June, as vibrant blue, purple, and white hydrangeas bloom in full splendor.
