Mount Kensomori, in the park

Towada-Hachimantai National Park (十和田八幡平国立公園) is a large national park in the Tohoku region of Japan, straddling the prefectures of Akita, Aomori and Iwate.

Understand

Famously beautiful, the park encompasses many scenic spots in two separate areas:

• Towada-Hakkoda area (north)
  • Lake Towada (十和田湖 Towada-ko), Japan's third deepest
  • The Hakkōda (八甲田) mountain range
  • Oirase Rapids (奥入瀬渓流 Oirase-keiryu), famous for its fall colors

• Hachimantai area (south)
  • The plateau of Hachimantai (八幡平)

Climate

The winter in the northern mountains is harsh, and virtually all transport and accommodation is shut down between November and April.

Information Site

Ministry of Environment has an official bilingual webpage for the park.

Get in

Disaster in the Hakkōda Mountains In January 1902, a large group of Japanese Army soldiers became lost in a sudden blizzard in the Hakkōda Mountains that saw temperatures plunge to -41°C, the lowest recorded in Japanese history. 199 of 210 men died in what remains the deadliest incident ever in the history of modern mountain climbing, and a grim reminder of how viciously changeable weather in the mountains can be.

Towada-Hachimantai National Park covers a very large area, and can be tackled from a number of different directions.

For access to the northern side of the park (Lake Towada, the Oirase Valley, Hakkoda Mountains, Sukayu Onsen), JR bus lines are available from Aomori and Hachinohe—see bus section below.

For access to the central areas of the park, the JR Hanawa Line (花輪線) crosses the northern side of the Hachimantai Plateau, traveling from Odate in the west to Koma in the east, with through services on the private Iwate Ginga Railway (IGRいわて銀河鉄道) to Morioka. Note that the IGR is not covered by the Japan Rail Pass.

For the southernmost parts of the park, the JR Tazawako Line (田沢湖線) travels along the south edge of the Hachimantai Plateau, from Morioka to Daisen.

By bus

From north of the park, JR Bus Tohoku runs the Lake Towada Sightseeing Bus on two routes: the "Mizuumi" from Aomori to Towadako, running the full route in about 3 hours; the "Oirase" from Hachinohe to Towadako, in about 2 hours. Time and fare tables are available from the JR site, linked. This bus is free for holders of the Japan Rail Pass, but not the JR East Pass. The sightseeing bus routes require reservation from a JR Travel Service Center.

This is a picturesque trip in a 45-person-capacity bus with a recorded tour commentary in Japanese and English, spanning from mountain passes through the Hakkodas on the Aomori route, alongside the Oirase Stream and falls on both routes, and ending at Towada lakeside. It is particularly stunning when leaves are turning in autumn, visible earlier on the route from Aomori passing through higher elevations.

Note that the hours of JR Travel Service Centers are typically from 10:00 to 17:30, including Aomori and Hachinohe. Thus they open later than many of the daily departures for these routes—to take one of the earlier busses, be certain to make a reservation at least the day before (from any JR Travel Service Center). There is a service center at Aomori Station (in the city), not only at Shin-Aomori.

Get around

By bike

Bicycle rentals are available at Yakeyama (焼山) and Nenokuchi (子の口) for about ¥600 per 2 hours.

People who rent a bike at one place can leave it at another place for an extra fee.

In Towadako, bikes can be rented from Towadako Backpackers guesthouse for ¥500 daily.

By boat

• 1 Towadako Ferries, ☏ +81 176-53-3083, fax: +81 176-53-8525, info@lakeship-towada.co.jp. You can take a boat tour from Yasumiya (休屋) around Lake Towada (45 minutes) or to Nenokuchi (50 minutes). Both cruises have a recorded guide (in Japanese) and show the beautiful rugged coast around the lake. Between late April and late November only. ¥1400. 

See

Choshi Otaki, the most famous waterfall of the Oirase Stream

• 1 Lake Towada (十和田湖). Lake Towada, or Towada-ko, is Honshu's largest volcanic caldera lake and also the country's third deepest lake. The area nearby is dotted with dense forests and waterfalls, and is the top tourist draw in all Tohoku. 
• 2 Oirase River (奥入瀬川). The upper reaches, known as literally as the Oirase Stream (奥入瀬渓流 Oirase-keiryu) or as the Oirase Gorge, are famously scenic, featuring constant-flowing water since this is the drain of Lake Towada, and numerous waterfalls. 
• 3 Hachimantai Plateau (八幡平). Located south of Lake Towada and bridges the central areas of Akita prefecture and Iwate prefecture. It is an area of ancient volcanic activity, and the entire plateau is dotted with boiling mud pools, steam and smoke vents and hot springs. (updated Apr 2024)

Do

There are countless hot springs in the park, especially on Hachimantai Plateau. The best known include Sukayu Onsen (酸ヶ湯温泉), Goshogake Onsen (後生掛温泉) and Toshichi Onsen (藤七温泉).

Yasumiya offers a 45-minute lake boat tour that lets you enjoy the picturesque scenery of the rugged coast formed by the two main peninsulas of Towada Lake. Or you can take the ferry between Yasumiya and Nenokuchi, which also passes by the two peninsulas and has a recorded guide.

• Lake Towada Winter Stories Festival (十和田湖冬物語). This annual February festival features fireworks every evening, light displays, snow sculptures, food stalls and hot wine. You can drink in an igloo bar where drinks are served in glasses made of ice. Many local inns and hotels offer shuttle service to and from the festival site. 

There are also a number of smallish ski resorts, which have banded together as Hakkoda Ski. The powder dumps in these parts can be epic, but the blizzard conditions can also be brutal.

Eat

Himemasu trout is served grilled and skewered at food stands near the lake. Towada barayaki, sauteed pork and onions, is another area specialty. Local ryokan inns may serve dishes made from well-known regional ingredients such as Akitakomachi rice and Aomori blackcurrants (すぐり, suguri).

Drink

Look for local brew Tazawako Beer (田沢湖ビール).

Lodging

• People can stop at the Oirase Youth Hostel for ¥3,360 per night.
• 1 Towadako Backpackers (十和田湖バックパッカーズ), Towadakohan-yasumiya, Okuse, Towada City, Aomori (at the eastern entrance of Yasumiya on road 103, 5-minute walk from JR Towadako bus station), ☏ +81 176-75-2606. A new backpackers hostel in a former guest house near the shore of Lake Towada.

Note that when they're open in colder months (e.g. October), an oil heater may be desired in your room—they ask an additional ¥500 nightly for this. Little no English spoken, but they are exceedingly welcoming. Payment by cash only. Dormitory bed for ¥2500, twin room for ¥5000, breakfast for ¥400, curry rice dinner for ¥600. 
• 2 Sukayu Onsen (酸ヶ湯温泉), ☏ +81 17-738-2428. One of the most famous old onsen in the area. The exterior and interior are of wood, and the main bath, though large, will unlikely hold up to 1000 people as it is famously claimed. The water is white and is reputedly good to treat reuma. The whole onsen smells of sulfur from the water, which adds to the charm once you get used to it. The large bath is open 24 hours and is one of the few remaining mixed-sex baths (be warned!), except 08:00-09:00 and 20:00-21:00 when it is female-only. It is near a nice short walk that takes you to a termal-heated wooded bench. Serious hikers can relax in this onsen after walking the Hakoda mountain. Rooms are Japanese style, and food is served in the room, ryokan style. Alternatively you can stay for a longer period and cook your own food in the cooking facilities. ¥7000 per person for the ryokan accommodation, ¥10000 on high season.
