⮱A unique summer marathon. Runners run up to an altitude of 2,700 meters, halfway up Mt. Norikura. It is a good season for sightseeing in Norikura if the weather is not bad. Norikura is famous for snow remaining in summer, and you can still see the famous snow walls (perhaps a bit shorter) on both sides of the road even in June.
