Hachimantai & Mount Iwate: Volcanic Highlands, Alpine Resort & Geothermal Springs — 2 Days

Founded in 1891, Koiwai is one of Japan's oldest and largest private dairy farms, a vast working estate of pasture, woodland and historic wooden barns at the foot of Mount Iwate. The visitor area, Makiba-en, opens part of the farm to the public: green meadows for walking, grazing cattle and sheep, horse rides and a small zoo for families, and above all the produce — rich soft-serve ice cream, cheese, yoghurt and a restaurant of farm dishes. The reason to come, though, is the setting: the meadows roll up toward the perfect cone of Mount Iwate, 'Nanbu Fuji', which fills the sky behind the farm and makes this one of the most photographed pastoral views in Tohoku. A relaxed, scenic start to the highlands.

Open roughly 09:00-17:00 (seasonal, shorter in winter); admission around ¥800 adult (approx., 2026). About 20 minutes by car from Morioka; bus service is seasonal. Mount Iwate is admired from the farm — the summit climb itself is restricted in 2026 under a volcanic alert. Allow about 2 hours.

A short way west of Morioka, the hot-spring town of Tsunagi sits along the shore of Lake Gosho, a reservoir formed by a dam on the Shizukuishi River with Mount Iwate rising beyond it. The springs here are old — legend ties them to the warrior Minamoto no Yoshiie, who is said to have tethered his horse to a stone while bathing, giving the town its name ('tsunagi' means 'to tether'). Today it is a relaxed cluster of ryokan and day-bath hotels along the water, with lakeside parks, a waterfront promenade and views to the mountain. It makes an easy lunch and stroll stop between the farm and the climb to Appi — soak your feet at a footbath, eat by the lake, and enjoy the open highland light.

The lakeside parks and promenade are free and open; day-bath hotels and footbaths keep their own hours and small fees (approx., 2026). About 20 minutes by car or bus west of Morioka. A relaxed lunch-and-stroll stop rather than a ticketed sight. Allow about 75 minutes.

High on the Appi plateau, this is the luxury anchor of the Iwate highlands — a contemporary mountain resort hotel opened in 2021 within the larger Appi Kogen ski-and-summer area. Wide windows frame the surrounding beech forest and ski slopes, and the hotel pairs international comfort with regional character: spacious rooms, an indoor pool and spa, hot-spring bathing, and dining that draws on Iwate beef, seafood from the Sanriku coast and highland vegetables. In summer the resort is a base for hiking, golf and the beech-forest trails; in winter it sits on some of the most reliable powder snow in Honshu. After a day in the open country, it is a polished, comfortable place to spend the highland night.

Check-in typically from mid-afternoon; rates from roughly ¥40,000 per room (approx., 2026, much higher in peak ski season). In the Appi Kogen resort, about 50 minutes by car from Morioka, or by train to Appi-Kogen Station plus a short shuttle. Book well ahead for ski season. Allow the evening.

Before leaving the plateau, ride the Appi gondola up the mountain for the long view: in green season it lifts you over ski runs turned to wildflower meadow to a highland of walking trails, with the cone of Mount Iwate and the Hachimantai range spread out around you. Below the base spreads the 'Buna-no-mori', one of the largest stands of natural beech forest accessible in Tohoku, threaded with gentle marked trails where the light comes green through the canopy and the forest floor is thick with ferns and birdsong. It is an easy, restorative morning of mountain air — a short loop in the beech wood or the full gondola ascent — before the drive across the high country. In winter this is all ski terrain.

The green-season gondola runs roughly 09:00-16:00 in summer/autumn (closed between seasons — confirm 2026 dates); a round trip is around ¥1,500-2,000 (approx., 2026). The beech-forest trails are free. At the Appi resort base. Allow about 90 minutes.

The Hachimantai Aspite Line is one of Japan's great mountain drives — a toll-free scenic road that climbs in switchbacks to the broad volcanic plateau on the Iwate-Akita border, walls of snow towering over the road in spring. At the top, near the Mikaeri-toge pass, a network of boardwalks loops out across the alpine marshes past mirror-still ponds and, on a clear day, views to Mount Iwate and the surrounding peaks; the gentle Hachimantai summit walk takes under an hour. This is also the home of the celebrated 'Dragon Eye' — a ring of meltwater that opens in the snow over Kagami-numa pond, resembling a great eye — but it appears only in a narrow window from roughly late May to mid-June and depends entirely on the year's snow, so it is a bonus rather than a promise. The road is open only in the snow-free season.

The Aspite Line is free; in 2026 it is open roughly April 15-November 4 (snow-closed otherwise, and night closures may apply). The summit boardwalks are free; the rest house and parking are at Mikaeri-toge. The 'Dragon Eye' appears only ~late May-mid June and is not guaranteed. The direct summit-to-Matsukawa Jukai Line pass is closed in 2026 — descend the eastern Aspite Line. Allow about 2 hours.

Tucked in a forested valley on the eastern flank of Hachimantai, Matsukawa Onsen is one of the oldest geothermal hot springs in Japan, set beside the country's first geothermal power station whose plumes of steam rise from the woods. Kyounsou is a friendly mountain inn here with milky, sulphur-rich kakenagashi baths — water that pours straight from the source and is never recirculated — including a fine open-air rotenburo looking out into the trees, the smell of sulphur sharp in the mountain air. You can stop for a day-use bath on the way down from the plateau, or stay the night for a quieter, rustic alternative to the Appi resort. After the high open country, the steaming, cloudy water is exactly the right way to end the highland route.

Day-use bathing is usually available roughly 09:00-16:00 for a small fee (around ¥600, approx., 2026); overnight rates from roughly ¥11,000 per person with two meals. In the Matsukawa valley, reached from the Matsuo/valley side (the summit pass is closed in 2026). About 40 minutes by car below the plateau. Allow about 90 minutes for a day-bath.
