Reaching the Hachimantai Area: Gateway Routes
Because Hachimantai straddles the border of Iwate and Akita prefectures, travelers typically enter through two primary gateways: Morioka City (Iwate Side) to the east or Tazawako/Kazuno (Akita Side) to the west. Depending on whether you choose public transportation or a self-drive rental, here is how to navigate your arrival.
By Bullet Train (Tohoku Shinkansen) + Bus
Using Japan’s high-speed rail network is the most efficient option for non-drivers traveling from major hubs like Tokyo, Sendai (仙台), or Aomori.
Option A: The Iwate Gateway via Morioka Station (Recommended)
Morioka Station (盛岡駅) serves as the primary hub for accessing Hachimantai’s resort towns, hot springs, and summit trails. You can choose from year-round local bus services operated by Ugo Kōtsū (suspended from 2026) and the seasonal Hachimantai Shizen Sansaku Bus (Nature Explorer Bus, 八幡平自然散策バス) by Northern Iwate Transportation Inc. (岩手県北バス).
- Train: Board the JR Tohoku Shinkansen (Hayabusa or Yamabiko) from Tokyo Station to Morioka Station (~2 hrs 10 mins via Hayabusa).
- Hachimantai Shizen Sansaku Bus (operates from mid-April to late October): Head to Bus Stop No. 3 outside Morioka Station’s East Exit.
- To Hachimantai Onsen Town / Mountain Hotel: ~1 hour 30 minutes
- To Hachimantai Summit (Hachimantai Chōjō): ~1 hour 55 minutes
- Refer to Northern Iwate Transportation Inc. website for the bus timetable.
- Bonus Walking Tour: Passengers holding a Hachimantai Shizen Sansaku Bus ticket can join a complimentary Japanese-guided walking tour departing directly from the Hachimantai Summit Rest House around 11:05 AM daily from early June to mid-October.
- Ticketing & Passes: You can’t reserve bus tickets in advance.
- One-Way to Summit (行き券／帰り券): ¥1,700 (Adults) / ¥850 (Children).
- Bus fares are paid when getting off.
- 1-Day Local Area Free Pass (八幡平エリアフリー券): ¥1,600 (Adults) / ¥800 (Children)
- The area free pass covers local transit between attractions and the summit.
- Onsen Stay Combo Pass (行き・宿まで券／宿から・帰り券): ¥2,300 (Adults) / ¥1,150 (Children)
- The one-way pass allows a stopover at Hachimantai Onsen Town (八幡平温泉郷) or Matsukawa Onsen before returning to Morioka Station.
- It is the best pass for those who plan to explore the summit area and stay at Matsukawa Onsen or the Hachimantai Onsen resort area, or for those who wish to explore the summit area the day after their stay before heading to Morioka.
- Where to Buy the Passes:
- At JR Morioka Station, purchase at the Iwate Prefectural Transportation Information Center near East Exit Bus Stop No. 7.
- At the summit, buy at the Hachimantai Mountaintop Rest House.
- In the lower resort areas, tickets are available at select hotels (e.g., Hachimantai Rising Sun Hotel (八幡平ライジングサンホテル), Hachimantai Heights (八幡平ハイツ), Hachimantai Mountain Hotel (八幡平マウンテンホテル)) and the three onsen ryokan in Matsukawa Onsen (松川温泉).
- One-Way to Summit (行き券／帰り券): ¥1,700 (Adults) / ¥850 (Children).
- Refer to the Northern Iwate Transportation Inc. website for more information about Hachimantai Shizen Sansaku Bus.
Option B: The Akita Gateway via Tazawako Station (Currently Suspended)
If you are approaching from Akita Prefecture or exploring nearby areas like Lake Tazawa (田沢湖) or Nyuto Onsen (乳頭温泉郷):
Important: The bus service operates seasonally from mid-April to mid-October.
- Train: Board the JR Akita Shinkansen (Komachi) from Tokyo to Tazawako Station (~2 hrs 45 mins).
- Connecting Bus: From Tazawako Station, catch Ugo Kōtsū’s (羽後交通) Hachimantai Line (八幡平線) bound for Hachimantai Chōjō (八幡平頂上).
- Service Alert: Route coverage can vary by season, and operations may temporarily terminate early at Tamagawa Onsen (玉川温泉). Always verify the latest seasonal timetables before departing.
Alternatively, local JR train lines connect to Kazuno-Hanawa Station, where local buses serve the western entrance of the Aspite Line.
By Car (Self-Drive)
Renting a vehicle offers total flexibility across the Aspite and Jukai Lines. Car rental counters (Toyota, Nippon, Times) are situated directly outside Morioka Station, Tazawako Station, Akita Airport, and Iwate Hanamaki Airport.
| Starting Point | Driving Route | Distance | Estimated Time |
| Morioka Station | Tohoku Expressway (Morioka IC → Matsuo-Hachimantai IC) → Route 237 | ~45 km | 45–50 mins |
| Morioka Station | Highway Route 4 / Route 282 (Toll-Free) | ~42 km | 60–70 mins |
| Hanamaki Airport (HNA) | Tohoku Expressway (Hanamaki IC → Matsuo-Hachimantai IC) | ~75 km | 1 hr 10 mins |
| Akita Airport (AXT) | Akita Expressway → Tohoku Expressway (Matsuo-Hachimantai IC) | ~140 km | 2 hrs |
Pro Tip: Mountain passes are subject to weather shutdown and strict winter closures. Always confirm expressways and mountain roads are clear and open before setting out. If driving via expressway, set your GPS to Matsuo-Hachimantai Interchange (IC), located just 15 minutes from the Aspite Line gate.
Seasonal Road Closures & Crucial Travel Tips
Driving the Hachimantai mountain passes is one of Tohoku’s premier road trips, but high elevation brings dramatic weather variations. Because the routes cross volcanic terrain exceeding 1,500 meters, both the Aspite Line and Jukai Line are subject to strict seasonal schedule constraints and sudden closures.
Winter Closure Schedules (Full Shut-Down)
Both the Aspite Line and Jukai Line are completely closed to all vehicular traffic throughout the winter due to heavy snowfall and dangerous blizzard conditions.
| Route | Annual Reopening Date | Annual Winter Closure Date | Status |
| Hachimantai Aspite Line | Mid-to-Late April (Approx. April 15–20) | Early November (Approx. Nov 5–10) | Closed to all traffic ~5.5 months |
| Hachimantai Jukai Line | Late April (Usually a few days after Aspite) | Early November (Same as Aspite) | Closed to all traffic ~5.5 months |
The exact opening date varies each spring depending on snow removal progress. The official clearance event marks the unveiling of the famed Snow Corridor (Yuki-no-Otowake), where carved snow walls stand up to 8 meters high on either side of the road.
Frozen Road Warnings & Nighttime Gate Closures (夜間通行止め)
Even during the operational months (mid-April through early November), spring and autumn bring freezing temperature drops that create hazardous black ice.
1. Nighttime Closures (Spring & Late Autumn)
- When: From reopening in mid-April through mid-May, and again from mid-October until the winter shutdown in November.
- Gate Hours: Road gates automatically lock from 5:00 PM to 8:30 AM.
- Rule: Drivers must pass through the entry gates before 5:00 PM. Remaining at the summit after 5:00 PM risks getting locked inside the mountain pass overnight.
2. Temporary Weather Bans
- During late April and early May, sudden blizzards or freezing rain can trigger temporary daytime closures without prior notice.
- Always check the official Iwate Prefecture Road Information status or ask local tourist information centers in Morioka before heading up the mountain.
