Mount Asama fills the view as you ski. The slope belongs to the ANA Holiday Inn Resort Karuizawa on the Kita-Karuizawa plateau, and a free shuttle bus, booked in advance, runs from the south exit of Karuizawa Station, so a car is not essential.

The quality score leaves out how much snow falls (it uses temperature, frequency, rain and wind).

These are analyses of hot spring sources, not a list of baths you can visit. They date from 1910 to 2005, many from decades ago, so today’s temperature and chemistry may differ. Names are as recorded in Japanese. Temperature and pH bands follow Japan’s standard for analysing hot springs.
