Nasu Highlands is a cool-summer plateau under an active volcano, about 75 minutes north of Tokyo by Shinkansen. The resort belt sits roughly 600–1,000 m up, so midsummer highs hover around 25°C — noticeably cooler than the Kanto plain, which is why it has long been a summer retreat, with the imperial family’s villa in the forest here. This is the Nasu area of Nikko National Park. This guide covers the highland: riding the ropeway up Mt. Chausu, the sulphur springs and the “killing stone,” the free dairy farm, and how to reach it all by train or car in 2026.

Why Nasu is a cool escape

The cool comes from altitude. The Nasu Kogen resort belt runs roughly 600 to 1,000 metres above sea level, and by the standard rule of about 0.6°C lost per 100 metres, that puts it several degrees below the Kanto plain on the same day — midsummer highs sit around 25°C while Tokyo swelters. It has been a recognised summer retreat (hisho-chi) for well over a century. Above the resorts, the land tips up into the bare, steaming Nasu volcano group, and that contrast — cool pastures below, volcanic summits above — is the shape of a Nasu day.

Riding the Nasu Ropeway up Mt. Chausu

The main event up top is the Nasu Ropeway, which climbs the flank of Mt. Chausu (Chausudake) — at 1,915 m the main peak of the Nasu volcano group, and an active volcano. The cabin runs from the base station at about 1,391 m up to the top station at 1,684 m in roughly four minutes, leaving you on open, wind-scoured slopes with long views back over the highland. Reaching the true summit from the top station is a further climb of roughly 50 minutes on foot over open volcanic ground — an estimate, not a stroll, so check the conditions and the alert first.

The volcanic side: the “killing stone” and the sulphur springs

Down at the foot of the volcano is one of Nasu’s strangest sights. Sessho-seki, the “killing stone,” sits in a barren lava field called Sai-no-kawara where volcanic gases — sulphur dioxide and hydrogen sulphide — seep from the ground, leaving the hollow bare of plants. In legend it is the petrified form of a murderous nine-tailed fox; the poet Bashō walked past it on his Oku no Hosomichi journey, and the rock famously split in 2022. A wooden boardwalk circuits the field — stay on it and follow the gas warnings.

Right beside it is Nasu Yumoto Onsen, the highland’s old hot-spring village, where sulphurous water has been drawn for centuries below the Onsen Shrine. It is the most atmospheric base for a night, and — usefully — it sits directly on the bus line up from the station.

Beyond the volcano: farms, forest and a suspension bridge

Most of a Nasu day is spent lower down, in the green belt of farms and forest. These are the highland’s easy, family-friendly stops.

How do I get to Nasu Highlands?

Nasu is one of the easier highland escapes to reach without a car — but only in season.

By train + bus (car-free, April–November)

1. Take the Tohoku Shinkansen from Tokyo to Nasushiobara Station — about 75 minutes on the Nasuno service.
2. From the station’s West Exit, ride the Kanto Bus “Nasu Line” up through Nasu Yumoto Onsen to the Nasu Ropeway base — about 75 minutes, ¥1,640 one way.
3. Get off at your onsen, farm or the ropeway along the way; the bus threads the main highland sights.

By car

Leave the Tohoku Expressway at the Nasu IC (or the ETC-only Nasu Kogen Smart IC) and climb Prefectural Route 17, the old Volcano Highway, up to the ropeway — roughly 30 minutes from the interchange. Parking at the ropeway base is free (about 150 spaces), but it can fill and lock during the summer holidays and autumn foliage, when a prefectural overflow lot a short walk down the trail takes the spillover. A car also unlocks the pensions and glamping sites spread off the bus line.

Flying in

There’s no practical airport at the door — Fukushima Airport is small and transfer-heavy. International and Southeast-Asian travelers reach Nasu the same way most Tokyo day-trippers do: into Haneda or Narita, across to central Tokyo, then the Shinkansen to Nasushiobara.

Where to stay

For atmosphere and the easiest car-free trip, sleep in Nasu Yumoto Onsen — the old sulphur-spring village nearest the volcano, lined with ryokan and right on the Kanto Bus line, so you can arrive and get around without a car. The wider Nasu Kogen highland spreads out into resort hotels, log-cabin pensions and a growing cluster of glamping sites (some on working dairy ranches) — characterful, but many sit off the bus route, so they suit a car or a lodging shuttle. For the most hotel choice and English support, Nasushiobara and the plain below are the fallback.

When to visit

July and August are the sweet spot: the highland stays around 25°C while the plain bakes, and the ropeway and Mt. Chausu hiking season is in full swing. Go on a weekday morning to beat both the heat below and the parking lockouts up top. Spring brings azaleas to the slopes; autumn brings foliage and the year’s biggest crowds. Winter is quiet and cold — the ropeway closes and the buses stop short — but the onsen are at their best.

Make it a wider trip

Nasu pairs naturally with the highlands and waterfalls just west of it — the falls around Nikko, Shiobara and Nasu are an easy add-on. If you’re building a cool-weather itinerary, Nasu is one of the stops in my guide to Japan’s coolest summer drives, and it fits the wider 2026 coolcation idea of trading the lowland heat for altitude.

Practical tips

• Check the volcano status. Chausu is active — read the JMA Nasudake alert before hiking above the ropeway top station.
• Buy the bus pass. The 1-day (¥1,500) or 2-day (¥3,000) Kanto Bus pass beats paying per ride.
• Mind the season. Ropeway and full bus service run roughly April–November; winter closes both.
• Layer up top. The base is mild, but the exposed 1,684 m top station is windy and cool even in August.
• Arrive early on peak days. The free ropeway lot locks when full in the summer holidays and foliage season.
