Shibu Onsen – Nagano

Shibu Onsen is a historic hot spring town located in Yamanouchi, Nagano Prefecture, near the famous Jigokudani Monkey Park where wild Japanese macaques bathe in natural hot springs. With its traditional ryokan inns, narrow cobblestone streets, and centuries-old bathhouses, Shibu Onsen offers a truly authentic Japanese onsen experience.

History & Atmosphere

Shibu Onsen has a history of more than 1,300 years.
According to legend, the hot springs were discovered in the 8th century by a Buddhist monk.
It flourished during the Edo period as a rest stop for travelers and samurai.
Today, it retains its retro atmosphere with wooden inns, stone-paved alleys, lantern-lit streets, and traditional yukata-clad guests walking between baths.

Hot Springs & Bathing Culture

1. The Nine Public Baths (九湯めぐり)

Shibu Onsen is famous for its nine communal bathhouses, each with unique healing properties.
They are numbered from Bath #1 to Bath #9 and are believed to cure different ailments (e.g., digestion, skin health, recovery from fatigue).
Traditionally, visitors staying at a ryokan in Shibu Onsen receive a master key (外湯めぐりの鍵) that allows them to try all nine baths.
The nine-bath pilgrimage is considered both a spiritual and wellness journey. Completing all nine is said to bring good fortune and longevity.

2. Ryokan Baths

Many inns have their own private onsen baths, both indoor and outdoor, often with natural hot spring water directly sourced.
Some ryokan offer kashikiri (private-use baths) for couples or families.

3. Foot Baths & Public Spaces

Along the town streets, you’ll also find ashiyu (hot spring foot baths) for a quick, casual soak.

Townscape & Experience

The main street is lined with traditional ryokan, souvenir shops, and small eateries.
Guests usually wear yukata (light cotton kimono) and wooden geta sandals while strolling through town, creating a timeless atmosphere.
At night, the lantern-lit alleys make the town look like a scene from old Japan.
