A Century of
Japanese Hospitality

Since 1919, Ryokan Omori has welcomed generations of travelers to the heart of Ikaho Onsen. More than a place to stay, it has always been a place to slow down, to feel cared for, and to experience the quiet warmth of Japanese hospitality.

As we begin our second century, that promise remains unchanged. We look forward to welcoming you to Ryokan Omori.
