Medical Treatment
If you feel ill during your stay in Japan, you may wish to visit the hospital while you’re here. The Japan National Tourism Organization (JNTO) has organized a list of 320 hospitals around the country which can treat foreign guests in a number of languages. Nagano prefecture is home to 16 of these hospitals which are located conveniently in or around major cities.
See JNTO’s Official Medical Guide for more information about Japanese hospitals and to search for ones in the area that you’ll be traveling.
