- Kusatsu Onsen (basically an onsen with the hot-watersource in the centre of the town)

- Hiroshima, I cannot stress how nice this city is.

- Arima Onsen (another onsen resort, the oldest of Japan)

- Nikko (the most lavishly decorated temples combined with mountains, touge, a beautiful lake and one of the highest waterfalls in the country)

Nikko is my absolute favorite place in all of Japan. I highly recommend it.
