Kakunodate, Lake Tazawa and Nyuto Onsen driving guide: samurai district, lakeshore loop and hot springs

The Kakunodate, Lake Tazawa and Nyuto Onsen area spans Semboku City in eastern Akita Prefecture, linking the preserved black-fenced samurai residences of Kakunodate, the emerald rapids of Dakigaeri Valley, 423.4 m-deep Lake Tazawa—Japan's deepest caldera lake—and the beech-forest hot-spring inns of Nyuto Onsenkyo on the slopes of Mt. Akita-Komagatake. National Route 46 (via Sengan Tunnel), the lakeshore loop around Lake Tazawa and Prefectural Route 194 up to Nyuto Onsenkyo are cleared of snow and open year-round between Akita Airport/Akita City and Morioka IC in Iwate Prefecture, whereas National Route 341 north through Tamagawa Onsen towards Kazuno and the Hachimantai Aspite Line close progressively for winter from November.

This guide follows a full-day route from Michi-no-Eki Kyowa in the west through Kakunodate, Dakigaeri Valley, a clockwise loop of Lake Tazawa and Nyuto Onsenkyo, crossing Sengan Tunnel to Michi-no-Eki Shizukuishi Anekko on the Iwate side, with winter road rules, parking hours, day-bath cutoffs and refuelling advice set out below.

Recommended drives

First visit: one day from Kakunodate via the Lake Tazawa loop to Nyuto Onsenkyo

Begin at Michi-no-Eki Kyowa (1) on Route 46—convenient from Akita Airport and Kyowa IC on the Akita Expressway—and head east for about 20 minutes to the Kakunodate Samurai District (2). Park at Semboku Municipal Sakura-namiki Car Park to stroll past the black wooden fences of Omotemachi and Higashi-Shorakucho, the Kakunodate Cherry Bark Craft Center, and the Aoyagi and Ishiguro samurai houses, then drive 15 minutes east to Dakigaeri Valley (3) to look out over the turquoise gorge from the red Kami-no-Iwabashi suspension bridge.

Around midday, head north on Routes 46 and 341 and enter the eastern shore of Lake Tazawa via Haruyama for Tazawako Resthouse & Shirahama Pier (4). Circle the lakeshore clockwise past Tazawako Kunimasu Mirai Museum (5), which displays live specimens of the rediscovered kunimasu trout, the golden Tatsuko Statue & Kansagu (Ukiki Shrine) (6) on the western shore, and the vermilion lakeshore torii at Goza-no-Ishi Shrine (7) on the northern shore. In the afternoon, turn off Route 341 at Kosendatsu Intersection onto Prefectural Route 194, pausing at Alpa Komakusa (8) for a wide view back over Lake Tazawa before soaking at historic Tsurunoyu Onsen (9) or roadside Kyukamura Nyuto-Onsenkyo (10). Finish by descending to Route 46 and crossing Sengan Tunnel into Iwate Prefecture to Michi-no-Eki Shizukuishi Anekko (11) en route to Morioka IC or JR Morioka Station (drivers starting in Morioka can follow markers 11 to 1 in reverse).

The route is about 138 km, with around 2 hours 35 minutes of driving. Distance and driving time are calculated from map data and exclude traffic, walking and bathing stops. Every public road on the route is toll-free.

Winter closures and private-car restrictions on Route 341 (Tamagawa Onsen) and mountain roads

Continuing north from Lake Tazawa on National Route 341 to the acidic geothermal valley of Tamagawa Onsen & Obuki (12) and onward to Kazuno or Lake Towada is subject to staged late-autumn and winter closures. From 13 to 30 November 2026, Route 341 closes overnight every evening from 18:00 to 8:00 the next morning between Play Park Tose (Choja-no-Yakata) and the Kazuno city boundary (Yanagisawa Gate), and Tamagawa Onsen's main inn finishes its 2026 operating season on Sunday 29 November (closed for winter from 30 November 2026 to 16 April 2027).

From 18:00 on Monday 30 November 2026 until 10:00 on Thursday 15 April 2027 (scheduled), the 9.4 km mountain section between the Shin-Tamagawa Onsen entrance and Yanagisawa in Hachimantai, Kazuno closes completely to all traffic, blocking through drives north. Over the same winter period, the 19.9 km stretch from Tamagawa Dam Site (former Nikamikan) to Shin-Tamagawa Onsen is closed to private and rental cars (open 8:45–14:30 to permitted route buses only, and closed to all vehicles 14:30–8:45); winter guests and day bathers visiting sister inn Shin-Tamagawa Onsen leave their cars at Shin-Tamagawa's winter car park near JR Tazawako Station and board the route bus at Shochugakko-kado bus stop. In addition, the Hachimantai Aspite Line (Prefectural Route 23) closed for winter at 17:00 on 4 November, Prefectural Route 127 to the Mt. Akita-Komagatake 8th Station closed at 12:00 on 30 October, and shortcut Prefectural Route 248 (Haruyama-Tazawa Line) down to Shirahama closed at 12:00 on 13 November—so always enter Lake Tazawa's eastern shore via Route 341 Kosendatsu Intersection and Prefectural Route 38 at Haruyama.

Kakunodate parking seasons and Nyuto Onsenkyo day-bath hours and closed days

Vehicles cannot stop or park along the narrow Kakunodate Samurai District street itself. From 1 April to 30 November, Semboku Municipal Sakura-namiki Car Park (8:30–16:30; ¥500 for ordinary cars, ¥1,000 for medium vehicles, ¥3,000 for buses) sits right between the Hinokinai River embankment and the samurai street. From 1 December to 31 March, Sakura-namiki Car Park is unploughed and closed for use as a medical-helicopter landing zone, so winter drivers use nearby parking such as the spaces in front of the Kakunodate Cherry Bark Craft Center. During the spring Cherry Blossom Festival (mid-April to 5 May) and early-to-mid-November foliage weekends, car parks fill in the morning and pedestrian-only zones operate on the samurai street in spring.

Day-trip bathing in Nyuto Onsenkyo finishes early in the afternoon. Tsurunoyu Onsen accepts day bathers from 10:00 until 15:00 last entry (¥700 for adults), and closes its open-air baths to day visitors every Monday for cleaning (or on the nearest weekday when Monday falls on a public holiday). Kyukamura Nyuto-Onsenkyo accepts day bathers daily from 11:00 until 15:00 last entry (¥800 for adults; 100 free outdoor spaces right on Prefectural Route 194), making it an easy choice if you prefer to avoid the narrow 3 km forest lane into Tsurunoyu on snowy days. If you arrive after 15:00, head back down to Alpa Komakusa (last entry 15:30, closed Thursdays, adults ¥550) or continue to Shin-Hashiba-no-Yu at Michi-no-Eki Shizukuishi Anekko on Route 46 (last entry 19:30, adults ¥620). Note that the former lakeside facility Tazawako Herb Garden "Heart-Herb" closed permanently on 31 August 2025.

Getting there and fuel

Semboku City has no Michi-no-Eki of its own, and none of the three gateway roadside stations (Kyowa, Shizukuishi Anekko and Nakasen) has a petrol station. There are also no fuel stations along the western and northern shores of Lake Tazawa, up Prefectural Route 194 in Nyuto Onsenkyo, or north of Tamagawa Dam on Route 341, so top up along the Route 46/105 bypass in Kakunodate or around JR Tazawako Station and Route 341 Kosendatsu Intersection before climbing into the hills. Neither Michi-no-Eki Kyowa nor Michi-no-Eki Shizukuishi Anekko has an EV charger, so charge ahead in Akita City, central Daisen or around Morioka IC.

If you don't have a car

Flying into Akita Airport, compare terminal counter walks, shuttles and standard winter snow-tyre dates across all six branches in Akita Airport Car Rental: 6 Branches Compared, or browse pickup options statewide in the Akita car rental directory. Arriving from Tokyo or Sendai by Shinkansen on the eastern side, Morioka Station Car Rental: 8 Companies Compared puts you about an hour from Lake Tazawa via Route 46. For expressway tolls, one-way drops between Akita Airport and Morioka, and seasonal mountain-pass planning, check ETC Cards for Rental Cars in Japan, One-Way Car Rental in Japan and Japan Winter Road Closures 2026–27, plus driving in Japan on a foreign licence and airport car rental pickup and return.

Frequently asked questions

What is the best order for driving Kakunodate, Lake Tazawa and Nyuto Onsen in one day?

Start on Route 46 at Michi-no-Eki Kyowa from the Akita Airport or Kyowa IC side, visit the Kakunodate Samurai District (Sakura-namiki Car Park) and Dakigaeri Valley in the morning, circle Lake Tazawa clockwise via Shirahama, Kunimasu Mirai Museum, the Tatsuko Statue and Goza-no-Ishi Shrine around midday, climb Prefectural Route 194 in the afternoon to Alpa Komakusa and either Tsurunoyu Onsen or Kyukamura Nyuto-Onsenkyo before the 15:00 bath cutoff, and cross Sengan Tunnel to Michi-no-Eki Shizukuishi Anekko towards Morioka. That totals about 138 km and around 2 hours 35 minutes of driving (reverse the order if starting from Morioka IC or Morioka Station).

Can I drive a rental car to Lake Tazawa and Nyuto Onsenkyo in winter?

Yes. Route 46 (including Sengan Tunnel), the Lake Tazawa loop (Prefectural Routes 38, 60 and 247) and Prefectural Route 194 up to Alpa Komakusa, Kyukamura Nyuto-Onsenkyo and Tsurunoyu Onsen are snowploughed throughout winter. Snow tyres are essential from November to April, and a 4WD car is recommended for midwinter climbs and the narrow 3 km forest road into Tsurunoyu (Kuroyu Onsen at the far end closed for winter on 9 November, and shortcut Prefectural Route 248 to Shirahama closed on 13 November).

When do Tamagawa Onsen and National Route 341 close for winter?

In 2026, Route 341 closes overnight (18:00–8:00) between Play Park Tose and Yanagisawa Gate from 13 to 30 November, and Tamagawa Onsen's main inn ends its operating season on Sunday 29 November. From 18:00 on Monday 30 November 2026 until 10:00 on Thursday 15 April 2027 (scheduled), Shin-Tamagawa Onsen–Yanagisawa closes completely and Tamagawa Dam Site–Shin-Tamagawa Onsen closes to private cars (winter visitors to Shin-Tamagawa Onsen park near JR Tazawako Station and ride the route bus).

What are the day-bath hours and closed days in Nyuto Onsenkyo?

Tsurunoyu Onsen accepts day bathers from 10:00 until 15:00 last entry (adults ¥700), with open-air baths closed to day visitors every Monday for cleaning (or the nearest weekday if Monday is a public holiday). Kyukamura Nyuto-Onsenkyo—with 100 free parking spaces right on Prefectural Route 194—accepts day bathers daily year-round from 11:00 until 15:00 last entry (adults ¥800). After 15:00, use Alpa Komakusa (last entry 15:30, closed Thursdays, ¥550) or Shin-Hashiba-no-Yu at Michi-no-Eki Shizukuishi Anekko on Route 46 (last entry 19:30, ¥620).

Where is the best place to park for the Kakunodate Samurai District?

From 1 April to 30 November, use Semboku Municipal Sakura-namiki Car Park (8:30–16:30, ¥500 per entry for ordinary cars), a short walk from both the samurai street and the Hinokinai River embankment. From 1 December to 31 March, Sakura-namiki Car Park is unploughed and closed as a medical-helicopter landing site, so park at nearby winter-accessible lots such as the spaces by the Kakunodate Cherry Bark Craft Center.
