Nasu Onsen Travel Guide: Discover Hidden Hot Springs in Japan
Nasu Onsen is a historic hot spring area nestled in Nasu Kogen, Tochigi Prefecture.
Visitors can enjoy a unique bathing experience, from atmospheric hot springs steeped in history to secluded hot springs tucked away in nature.
This article introduces the best times to visit Nasu Onsen and the unique charms of its various hot springs.
With so many inviting hot springs to choose from, deciding where to go can be a challenge. This guide will help you plan your perfect visit.
What is Nasu Onsen Like?
Nasu Onsen is the collective name for the hot springs scattered throughout Nasu Town in Tochigi Prefecture, forming what is known as a hot spring area.
Each hot spring has its own mineral composition and reputed health benefits. Nasu Yumoto, for example, is known for its sulfur-rich waters, which have a distinctive aroma and are believed to help alleviate conditions such as high blood pressure, arteriosclerosis, and muscle pain.
Beyond Nasu Yumoto, the area offers a wide variety of hot springs, each with different mineral properties and potential benefits. One of the main attractions is the freedom to choose a hot spring based on your needs or visit several to compare their unique characteristics.
The history of Nasu Onsen dates back to the discovery of Shika-no-Yu. Following its establishment, more hot springs were discovered throughout what is now Nasu Town.
During the Edo period (1603-1868), the area became famous for its seven hot springs, collectively known as Nasu Shichiyu. From the Meiji period (1868-1912) onward, the area also came to be known as Nasu Juniyu (Twelve Hot Springs of Nasu) or Nasu Juichiyu (Eleven Hot Springs of Nasu).
During Japan's postwar period of rapid economic growth, the opening of the Tohoku Expressway and Tohoku Shinkansen improved access to the area. As a result, Nasu gained popularity as a vacation home destination.
Over time, however, some hot springs have fallen out of use, with their inns and facilities no longer remaining.
Despite these changes, Shika-no-Yu, where the history of Nasu Onsen began, remains a popular destination. Known for its relatively high water temperatures and distinctive sulfur aroma, it offers an authentic Japanese hot spring experience.
Although the area is not being extensively developed for tourism today, this is precisely what makes it special. Visitors can still discover historic hot springs steeped in tradition and secluded baths tucked away in remote natural settings.

The inn's greatest attraction is its abundant natural hot spring water, boasting the highest flow rate in the Nasu Onsen area.

5. Shin-Nasu Onsen: An Area with Hot Spring Inns and Day-Use Baths
Several hot spring inns scattered across the southern part of Nasu Onsen are collectively known as Shin-Nasu Onsen.

Despite being transported from another source, the water remains hot and is said to help relieve neuralgia and fatigue, among other conditions. It is classified as simple hot spring water.
Shin-Nasu Onsen offers a diverse selection of inns, ranging from charming retro-style properties to those featuring sophisticated modern designs.

Its alkaline simple hot spring water is colorless, odorless, and tasteless, and is said to help alleviate digestive disorders and chronic eczema.
One of the area's greatest attractions is the chance to admire a sky filled with countless stars. Since the inns generate their own electricity, only the soft glow of lamps remains after lights-out.
