Kaisei Town Hydrangea Festival
An annual festival held in June in Kaisei Town, Kanagawa, celebrating the rainbow-colored rural landscape created by rice paddies and hydrangeas. About 5,000 hydrangea plants bloom along farm roads and waterways across a vast area equivalent to about 3.6 Tokyo Domes. The 'Hydrangea Pond' with about 2,000 blooms floating on water is enchanting, with weekend illumination events. Now in its 39th edition, this historic festival is so popular that Odakyu Romancecar trains make special stops at Kaisei Station.
