Roughly 175km west of Tokyo, Nisiyama Onsen Keiunkan is officially the oldest hotel in the world as verified by Guinness World Records. Nestled within a mountainous region, it’s surrounded by natural hot springs that have helped attract visitors for more than 1,300 years. Although the six different baths at the resort are open for use 24 hours a day, tradition dictates that men and women frequent them at different times. The hotel offers both Japanese and Western-style rooms and despite the age of the venue, all the bathrooms thankfully offer modern amenities.
It is interesting that Japan has a bit of a monopoly on ancient hotels (the six oldest are all in the Land of the Rising Sun),
