Zao Onsen: The complete Travel Guide

Sulphur onsen, snow monsters and ski slopes

Zao Onsen is a hot spring village on the Yamagata side of the Zao mountains, about 40 minutes by bus or car from Yamagata Station. Its strongly acidic sulphur water has been used for roughly 1,900 years. Three public baths in the village cost JP¥200 (£0.95) for adults. In winter the slopes fill with skiers and the ropeways and gondolas carry visitors toward the snow monsters near the summit. Summer and autumn bring hiking and foliage. It suits a night or two with a ryokan bath at the end of the day.

Why travel to Zao Onsen?

The water is what sets Zao Onsen apart. The springs here are strongly acidic sulphur springs with a history of about 1,900 years. They're nicknamed the springs of beauty for the way the water is said to benefit skin. Three old communal baths named Shimoyu, Kawarayu and Kamiyu are open from 06:00 – 22:00 for JP¥200 (£0.95) while free footbaths and several day spas add more ways to soak. Winter is the other big draw and the ski area is one of the largest in Tohoku with 28 lifts and a longest run of about 10 km. Near the summit, frozen wind and heavy snow coat the trees into the shapes known as snow monsters, which are usually most striking around mid-February. Ropeways and gondolas carry non-skiers up to see them and the area is lit on selected evenings. The ski season runs from about mid-December to early May depending on snow. Outside winter the mountains stay worth the trip. Hiking and autumn leaves are the main draws and buses reach the Okama crater lake in season. Three cable cars leave from the village. Two days covers a bath, a day on the slopes or the summit and an evening in the village. The village works as a stand-alone winter trip or as a stop on a Yamagata loop that also takes in the prefecture's other sights.

Knowledge before you go

Take off silver and gold jewellery before bathing in the sulphur water.
Public baths have no showers and no soap, so rinse with the tub and leave valuables behind.
Snow monsters are usually most spectacular around mid-February, with evening illumination on selected nights.
The village was called Takayu until 1950 and one of its streets still carries that name.

How to travel to Zao Onsen

Buses from Yamagata Station are the usual way to reach Zao Onsen, taking about 40 minutes to the Zao Onsen Bus Terminal. They run several times a day but not every service runs every day, so check the timetable. A seasonal service continues from Yamagata Station through the village to Okama. Yamagata is on the Yamagata Shinkansen, about three hours from Tokyo. From Sendai Airport (SDJ) a bus goes to Yamagata Station in roughly one to one and a half hours. Yamagata Airport (GAJ) has an airport bus straight to Zao Onsen that connects with flights but it must be reserved by 17:00 the day before so plan ahead. By car the village is about 40 minutes from Yamagata City. Winter driving needs snow tyres and some care on the mountain roads. Buses are less stressful when snow is falling.

Access summary

From Yamagata Airport (GAJ): Bus to Yamagata Station, then bus, about 2 hours.
From Tokyo: Yamagata Shinkansen to Yamagata, bus to Zao Onsen, around 3 hours.
From Yamagata city: Yamako bus from Yamagata Station, roughly 40 minutes.

Where to stay in Zao Onsen

Zao Onsen has more than 80 places to stay, mostly ryokan and hotels with their own sulphur baths plus budget lodges. Most are clustered along the slope of the village close to the public baths and the cable car stations. A stay in a ryokan with an onsen bath is the main reason to sleep here. Booking pressure is highest at weekends in the ski season, especially around mid-February when the snow monsters peak and in the autumn foliage weeks. Reserve early for those dates. Staying in Yamagata City is an alternative since it has many more hotels around the station and the bus takes about 40 minutes. You give up the evening baths in the village and the quiet streets after dark, so it fits a day trip better than a full onsen stay.

How to get around Zao Onsen

Zao Onsen village is built on a steep slope and most of it can be covered on foot. The three public baths, the bus terminal and the ropeway stations are all within the village.

Walking:
Expect uphill climbs and, in winter, icy streets, so shoes with good grip help. The cable cars start in the village and are the way up to the summit area.

Buses and taxis:
In season, a bus goes between Yamagata Station, the village and Okama, which makes the crater lake easy to reach without a car. Taxis wait at the taxi station and can cover short hops when the weather is bad.

Car:
A car adds little for a stay in the village. If you do drive in winter, roads can be snowy and winter tyres are a must. Parking near the public baths is limited so it's easier to leave the car at your lodging.

Food in Zao Onsen

Food in Zao Onsen draws on the cooking of Yamagata, with mountain vegetables, buckwheat noodles and plenty of hearty winter dishes. Soba is a staple across the prefecture. Imoni, a taro and meat stew, is a Yamagata comfort dish. Jingisukan, grilled lamb cooked at the table, is also popular around the ski area. Local sake and fruit from the prefecture show up at many tables.

Most ryokan serve dinner and breakfast to guests, which is the easiest way to eat well. Restaurants and bars are concentrated along the main streets of the village and many close early outside peak periods.

Skiers can eat at lodges near the lifts. Vegetarians will find limited choices in ryokan meals so mention dietary needs when you book.

Safety information overview

General safety

Zao Onsen is very safe, with little crime. Winter brings heavy snow, ice and strong wind near the summit and off-piste skiing is risky. Mount Zao is an active volcano, so access to the Okama crater lake can be restricted.

Health & Medical

Yamagata City, about 40 minutes away, has the main hospitals. Village medical care is basic and English-speaking staff are uncommon. The acidic sulphur water can irritate dry skin and people with heart conditions are advised not to bathe. Ski injuries are the main concern.

Accessibility

Accessibility is limited. The village sits on a steep slope with stairs and icy streets in winter. Public baths are older wooden buildings with steps. Ropeways and buses help with the climb, though boarding in snow takes care.

Tap water

Tap water is safe to drink in Zao Onsen, as elsewhere in Japan. The hot spring water in the baths is strongly acidic and shouldn't be swallowed. Shops and vending machines sell bottled drinks in the village but trails have few, so carry water.
