What Is the Akita Shinkansen?

The Akita Shinkansen is a “mini-shinkansen”, like its Yamagata cousin — a hybrid that runs at full high speed on the Tohoku line, then continues onto re-gauged local tracks to reach a region no dedicated bullet-train line serves. Its striking red Komachi trains leave Tokyo coupled nose-to-nose with a green Hayabusa, race north to Morioka at up to 320 km/h, then split off and slow to a scenic 130 km/h over the Ou mountains to Akita on the Sea of Japan.

That second half is the beautiful part: the train winds past the deep-blue caldera of Lake Tazawa, through the samurai town of Kakunodate, and down into the rice plains of Akita. Since 2014 the line has run entirely on the sleek E6 series, and the single Komachi service links Tokyo to Akita in about 3 hr 40 min. Lakes, cherries, onsen and festivals are the themes.

Watch the split at Morioka: the red Komachi and the green Hayabusa uncouple on the platform and glide off in different directions — one of the most photographed pieces of everyday railway theatre in Japan.

How the Komachi Works

🚄 Komachi — the only service on the line, running Tokyo–Morioka–Akita. All seats are reserved (there are no unreserved cars). On the Tohoku section it flies at up to 320 km/h; from Morioka it runs on the narrow-gauge-width Tazawako and Ou lines at conventional speed, stopping at small mountain platforms and the occasional level crossing.

Some Komachi skip the small stop of Shizukuishi. Because the Morioka–Akita section shares regular tracks, winter snow can cause delays — allow a little buffer. The Japan Rail Pass and JR East passes cover the whole line.

The 6 Stations (from Morioka)

From east to west. Each links to our full area-and-hotel guide.

1. Morioka (Iwate) — the junction where the Komachi splits from the Tohoku line.

2. Shizukuishi (Iwate) — gateway to Mt. Iwate, Koiwai Farm and ski slopes.

3. Tazawako (Akita) — the door to Japan’s deepest lake and the secret baths of Nyuto Onsen.

4. Kakunodate (Akita) — the “Little Kyoto” samurai town famous for weeping cherries.

5. Omagari (Akita) — home of one of Japan’s greatest fireworks competitions.

6. Akita (Akita) — the terminus: the Kanto Festival, Namahage and kiritanpo.

Journey Times & Fares

Times are for the fastest Komachi; fares are approximate reserved-seat totals, one way.

The Japan Rail Pass and the JR East Tohoku pass cover the entire line, Komachi included — strong value for an Akita trip. Remember every seat is reserved, so book ahead in cherry and festival seasons.

Lakes, Cherries & Hidden Hot Springs

The Akita line packs an outsized share of Tohoku’s beauty into a short run. Lake Tazawa is the deepest lake in Japan, a cobalt-blue caldera ringed by mountains; above it, Nyuto Onsen hides some of the country’s most atmospheric secluded baths. Kakunodate is a perfectly preserved samurai quarter that turns pink with weeping cherry blossom each spring, and Omagari lights the August sky with a legendary fireworks contest. It is a line to take slowly.

Which Airports Connect to This Line?

✈️ Tokyo Haneda & Narita: Most travelers start from Tokyo and ride the Komachi straight through.

✈️ Akita Airport (AXT): About 40 minutes by bus from Akita city, with Tokyo, Osaka and other domestic flights — a handy western gateway for an open-jaw trip.

✈️ Odate-Noshiro Airport (ONJ): In northern Akita, an alternative for the prefecture’s north.

Where Should You Stay Along the Line?

Akita city is the main base, especially for the August Kanto Festival and Oga Peninsula trips. For scenery and onsen, sleep at Lake Tazawa or up at Nyuto Onsen; for history and cherries, stay in Kakunodate; and time Omagari around its fireworks. Each station guide above gives the honest verdict.
