The best time to visit Mori is during the summer months, from June to August, or in autumn, particularly September and October.Summer offers pleasant weather, with comfortable temperatures ideal for enjoying outdoor activities around Lake Onuma and the scenic countryside. This period is superb for nature lovers and families who want to explore the Mori area without the chill of winter. You can enjoy boat trips on the lake, cycling along its shores, or hiking in the nearby Komagatake mountain trails.Autumn provides stunning natural beauty as the leaves change colour, especially around Lake Onuma. The cooler, crisp air makes it a lovely time for walking and photography, capturing the vibrant reds, oranges, and yellows of the trees.
