Open since 705 AD – and YOU can still check in today!

Hidden in the mountains of Japan lies a place that breathes history: Nishiyama Onsen Keiunkan, founded in 705 AD, holds the Guinness World Record as the oldest continuously operating hotel in the world. 

52 generations – the same family. 

A place where once samurai and imperial envoys rested now welcomes travelers from 

around the globe to soak in natural hot springs and experience centuries of 

Japanese hospitality. 

Staying here means more than just booking a room, you’re sleeping inside the living history of Japan.
