Travel to Japan has increased drastically, particularly among Americans, but there’s also a growing trend drawing travelers beyond typical destinations like Tokyo and Kyoto. More and more U.S. tourists seek authentic, rural escapes, and one emerging Japanese destination is lush Kii Peninsula on Honshū.

Comprising the Mie, Wakayama and Nara Prefectures, Kii is an easy train ride from Kyoto or Osaka, but retains that remote feeling. In fact, the region is notable for its restorative hot springs found throughout the peninsula.

Here’s where you’ll find some of the best hot springs in Kii:
