Nishiyama Onsen Keiunkan is recognized as the world’s oldest hotel and one of the oldest continuously operating businesses of any kind. Founded in AD 705 in the mountains of Yamanashi Prefecture, Japan, it was established by Fujiwara Mahito and has welcomed travelers for more than 1,300 years.

The inn is renowned for its natural hot springs, whose waters flow directly from local geothermal sources. Over the centuries, it has hosted samurai, feudal lords, government officials, and modern-day visitors seeking traditional Japanese hospitality. Remarkably, the business has remained under the stewardship of the same family lineage for more than fifty generations.

Today, Nishiyama Onsen Keiunkan continues to operate as a luxury ryokan, blending centuries-old traditions with modern comforts while preserving its historic character. Its longevity stands as a testament to the enduring appeal of exceptional hospitality and the Japanese tradition of omotenashi—the art of wholehearted service.
