I recommend Nikko. There is Nikko that is in Tochigi prefecture. In autumn, You can enjoy colored leaves. See the Nikko Tosho-gu Meseum Art. You may understand the Japanese history. I recommend monkey and Iroha-zaka. Iroha-zaka is a slope. Vertical drop is about 500 meters. And curves are 48 times.

There are many sightseeing attractions in Nikko.
Nikko-Tosyogu(shrine), Senjyogahara, Kegonnotaki(waterfall), Nikko-Sarugundan(monkey’s entertainment) and so on.
Nikko is famous for autumn colors and hot springs.
The autumn colors are very beautiful and you can really relax at hot springs.
You can meet monkeys in Nikko-Sarugundan.
It's very entertaining to watch the monkeys playing.

There is a lot of trees.
