This place is called “momiji no tunnel.” A lot of tourists and locals come to visit during this time of year. In the evening, the maple trees are lit up and they look really fantastic.
Before the tunnel, you drive around Lake momiji (momiji ko) after seeing the Minowa Dam. The maple trees around the lake are also beautiful!
On November 3rd, there is an festival of Momiji Lake at the event square of Minowa town. There are lots of food stalls and some fun activities to take part in. Also, a walking event is held in the morning so you can walk 8km around the whole lake and enjoy the autumn colors at a relaxed pace.
For more info, please visit Minowa town tourism association.
