Atami Plum Garden is known for "Japan's slowest autumn foliage and earliest blooming plum trees." During the beautiful season of fresh greenery, the "Evening of Firefly Watching" is held at the Hatsukawa Clear Stream within the garden. The Genji firefly larvae released in March mature into adults from late May to June, allowing you to enjoy their fantastic glow. The sight of fireflies fluttering in the serene garden is like being in a fantasy world. Please come and enjoy the firefly viewing! Event dates: June 1, 2025, to June 8, 2025, from 19:00 to 21:00, Summer Location: Atami Plum Garden
