The best time to visit Okutama is typically during the spring (late March to May) and autumn (October to late November) months for pleasant weather and beautiful natural scenery.Spring in Okutama brings comfortable temperatures and the blooming of cherry blossoms, particularly around Lake Okutama and along the Tama River. It's an excellent time for hiking and enjoying the fresh air before the summer heat. The trails are generally well-maintained and offer views of the awakening forest.Autumn is another ideal period, known for its stunning autumn foliage. The mountainsides transform into a palette of reds, oranges, and yellows, making it superb for scenic drives, photography, and outdoor activities like hiking and canyoning. The cooler, crisp air is invigorating for exploring the natural parks and gorges.While summer (June to September) can be warm and humid with more rainfall, it's still a good time for water activities like kayaking and rafting in the Tama River, or escaping the city heat in the cooler mountain elevations.
