It'll be around a high of 75°F and a low of 55°F in Karuizawa mid-June (updated 5/30/24)

There is surprisingly no Uber in Karuizawa, so you have to call a taxi, drive, or walk.

Aloha attire; for men, aloha shirts with slacks are acceptable, for women, floral patterns are welcome to fit the aloha theme but the attire is not mandatory.

Guests with tattoos can enter the onsen if they cover the tattoos with fewer than eight stickers (measuring 3.94 inches x 3.15 inches each)
