The Minamisawa Hydrangea Mountain can be found in Akiruno, and each year from mid-June to early July a festival is held to celebrate thousands of flowers in bloom. The hydrangeas here have all been planted by one man - Mr. Chuichi Minamisawa - who originally started his endeavor with just 20 hydrangea seedlings. This has expanded now to around 10,000 plants and the creation of a popular tourist destination.
The entrance fee to the mountain during hydrangea season is 500 yen for adults and 300 yen for children.
