Zao Onsen Travel Guide: When to Go, How to Get There and What to Do
Zao Onsen is a mountain hot spring town in Yamagata Prefecture, known for sulphur waters, skiing and the rime-covered trees called juhyo in winter.

En bref
- It suits onsen and snow lovers: stay at least one night, or two if you want the ropeway plus skiing or scenic walking.
- The winter highlight is the juhyo, or snow monsters, roughly from late December to early March depending on conditions.
- The town is up in the mountains, reached from Yamagata Station by bus in roughly under an hour.
Zao Onsen is a hot spring town on the slopes of Mount Zao in Yamagata Prefecture in the Tohoku region, long known for its strong sulphur waters and as one of the region's major ski resorts. In winter, trees on the ridge are coated with snow and ice until they look like huge statues, called juhyo or snow monsters, a sight many people come to see. In summer and autumn the mountain turns to walking trails and views, so it can be visited nearly all year.

Who it suits and how many days
It suits people who enjoy onsen, snow and mountain rest. To soak with a view, stay at least one night; two nights is more comfortable if you want to ride the Zao Ropeway to the ridge, walk or ski, and fit in several baths. Anyone who dislikes cold or struggles on snow should prepare non-slip footwear and warm layers, and the town does not suit those wanting big-city shopping or varied entertainment.
Best time to go and weather
Winter is the popular season, with juhyo usually clearest from late December to early March, depending on that year's snowfall and temperature, so check current conditions on the ropeway and tourism sites before booking. Late spring brings melting snow and fresh leaves, summer is cooler than the plains, and autumn colour on the mountain tends to arrive before the lowlands and pairs well with the ropeway.
Getting there and getting around
From Tokyo, take the Yamagata Shinkansen to Yamagata Station, about two and a half to three hours, then a bus to Zao Onsen of roughly under an hour. You can also fly to Yamagata or Sendai and continue by train or bus. In the onsen town you can mostly walk, but steep slopes and snow slow you down, and the ropeway's lower station sits slightly outside the centre, so check bus times and ropeway operating hours carefully.

Main sights
- Zao Ropeway, taking you up the ridge to see juhyo in winter and mountain views in other seasons
- Okama, a round crater lake whose water changes colour with the light, reachable when the road and trail are open by season
- The onsen town and its public baths: stroll the old streets and soak in the distinctively scented sulphur water
- Skiing and snowboarding in winter, for both beginners and those used to snow
These sights depend heavily on weather. Roads to some viewpoints close seasonally and the ropeway may stop in strong wind, so keep a backup plan and check operator sites before leaving your lodging each day.
Minor sights and quieter spots
Beyond the main stops there are short forest walks when snow is absent, and other onsen towns in the prefecture such as Ginzan Onsen, with its wooden old-town feel by a river, though it lies in a different direction and is best treated as a separate trip. Yamagata city is itself a good base if you want both Zao and Yamadera temple in one trip.
Areas to know
- The town centre: lodging, public baths and restaurants in one place
- The lower ropeway station area: a short walk or ride from town, handy for skiers
- Around Yamagata Station: the prefecture's main city, a transfer point and overnight stop before the mountain

Food and souvenirs
Dishes travellers often try include Jingisukan (grilled lamb), a recognised local meal, plus Yamagata staples such as soba, imoni taro stew and seasonal fruit like cherries, a famous product of the prefecture. Popular souvenirs tend to be sweets, processed fruit and keepsakes from the baths. Check fruit seasons before you go.
Sample budget
Main costs are travel from Tokyo, onsen lodging, food, and the ropeway or ski fees if you use them. Each item changes by season and holiday, and snow season is usually pricier than other times. No fixed figures are given; check the latest prices on operator sites and compare several booking sites.
A short sample plan
- Day 1: arrive in the afternoon, check in, walk the town and soak before dinner
- Day 2: ride the ropeway in the morning when the sky is clear, then ski or walk, and soak again in the evening
- Day 3, if you have it: head down to Yamagata and add Yamadera temple before leaving
On a mountain where weather shifts quickly, data helps you check ropeway status, bus times and forecasts in real time. A Japan eSIM can be set up before departure, which is easier than hunting for a SIM on the way.
