Akayu Onsen: Hot Spring Guide & Visitor Access

Akayu Onsen in Nanyo City is an old hot spring said to date back roughly 900 years, to a time when a warrior healed his wounds here. Tradition holds that Minamoto no Yoshitsuna discovered the spring in 1093, and that the water turned red from the blood of his retainers washing their wounds, giving the spring its name (aka meaning red). It has long been cherished as one of the leading hot spring towns of the Okitama region. Set at the northern end of the Yonezawa Basin, it also served as a therapeutic retreat for the lords of the Yonezawa domain during the Edo period.

Highlights

Public bathhouses are scattered through the hot spring town, where you can enjoy the hot water alongside local residents. Among them is Yukotto, a communal bath newly built in 2022 by consolidating two aging bathhouses, and together with a drinking-spring spot near the source and a foot bath, it forms a base for bath-hopping. New facilities now anchor the center of the town while carrying on the heritage of its old public baths. The surrounding area is a wine country of spreading vineyards, and stays combined with winery visits are popular. With several sources and abundant flow, each inn offers its own character in how it uses the water.

Seasonal Highlights

From summer into autumn you can enjoy grape picking and new-vintage wine. The local wines, brewed to match the grape harvest, carry a flavor unique to this land. In spring, the cherry trees of Eboshiyama Park overlooking the hot spring town burst into bloom, drawing crowds of blossom viewers. Eboshiyama Park is known as one of Japan's notable cherry blossom spots, celebrated for its tunnels of blossoms and views framed by a stone torii gate.

Access and Basic Information

Akayu Station is about 5 minutes by bus, or a few minutes by taxi, and since the Yamagata Shinkansen stops here, access from the metropolitan area is convenient. Depending on the source, the water is a simple spring or a chloride spring, and the temperature is generally high, in the 50 to 60 degree Celsius range, with abundant flow. The pH of the sources is generally neutral to mildly alkaline, and the water is said to be gentle on the skin. Day-use bathing is accepted at the public baths and at some inns. Admission to the public baths is around a few hundred yen.

Practical Travel Notes

The cherry blossoms are usually at their best around mid-April, and Eboshiyama Park grows very lively during the viewing season. Wineries are scattered within driving range of the station and hot spring town, so if you want to enjoy tastings and direct sales, it is reassuring to arrange transport other than driving yourself. If you plan to enjoy tastings that involve alcohol, consider sharing driving with companions who will not drink, or using a taxi or shuttle. Public baths often cost only a few hundred yen, and combining winery visits with the foot bath and public baths can fill a leisurely half day to full day. A day trip budget of a few thousand yen covers bathing, a meal, and wine. Eboshiyama Park sits on a hill within walking distance of the town and makes a fine strolling course overlooking the streets during the cherry and autumn-leaf seasons.

A Word of Advice

The public baths tend to be hot, so it is wise to pour water over yourself first to let your body adjust before entering. If you are driving, remember the courtesies of a wine country and refrain from tasting. At drinking-spring spots, guidance on how and how much to drink is often posted, so check the notices before you taste.
