Oirase Stream Stroll

Transportation: You can take the JR bus from Lake Tazawa to the Oirase trail, or walk along the trail from Lake Tazawa to Oirase Stream. The trail follows the stream, but if it rains, it might be a bit challenging as the path is mostly muddy. The stream is very clear, and you'll encounter many waterfalls of various sizes along the way. Both sides of the stream are lined with trees, moss, and various types of mushrooms. However, note that there are very few stations with restrooms.
