When visiting Nagano, you absolutely should not miss Japan’s longest post town! This article provides a complete guide to transportation from Nagoya and Tokyo to “Narai-juku”, including must-see attractions along the old streets, recommended local cuisine, and must-buy souvenirs, helping you easily plan a one-day trip along the Nakasendo Road filled with the historical charm of the Edo period.
Located in Shiojiri City, Nagano Prefecture, at an altitude of approximately 940 meters, Narai-juku was the 34th post town along the “Nakasendo Road”, the main route connecting Edo (present-day Tokyo) and Kyoto during the Edo period. It was also one of the 11 post towns along the Kiso Road. The approximately 1-kilometer-long old street lined with thousands of lattice windows is known as “Japan’s longest post town”. In the past, due to the large number of travelers passing through, it became the most prosperous station town on the Kiso Road under the name “Narai Sengen”. Traditional wooden houses with lattice windows line both sides of the street, and the unique architectural style of the buildings has been designated as an Important Preservation District for Groups of Traditional Buildings by the Japanese government.

Narai-juku Transportation Guide
When traveling to Narai-juku, please note that Narai Station is only served by local trains, and limited express trains do not stop there. After arriving at the station, you can reach the old street area within approximately 1 to 3 minutes on foot. Since local trains on the JR Chuo Main Line run only about once every 1 to 2 hours, it is recommended to check the timetable before departure. In addition, the section of the Chuo Main Line between Shiojiri and Nakatsugawa (including Narai Station) is not within the IC card service area, so transportation IC cards such as Suica and ICOCA cannot be used for entry or exit. Please make sure to purchase a physical train ticket.

Frequently Asked Questions About Visiting Narai-juku
1. Where is Narai-juku? How can I get there? How much time is needed to explore the old street?
Narai-juku is located in Shiojiri City, Nagano Prefecture, and is a post town along the Kiso Road section of the Nakasendo. Narai Station is only served by local trains, so travelers need to first take a limited express train to “Kiso-Fukushima Station” or “Shiojiri Station” and then transfer to a local train. It takes approximately 2 hours from Nagoya. Since local trains are infrequent, driving or renting a car is a more flexible option. The attractions are concentrated along an approximately 1-kilometer-long old street. Simply walking, browsing shops, and visiting historical sites requires about 2 to 3 hours. If you want to enjoy meals leisurely and carefully explore each historical site, half a day is recommended.
2. What are the differences between Narai-juku, Tsumago-juku, and Magome-juku? Which one should I choose?
All three are post towns along the Kiso Road section of the Nakasendo. “Narai-juku” is Japan’s longest post town, stretching approximately 1 kilometer, with the highest altitude and the largest scale of preservation. “Tsumago-juku” is flat, simple, and quiet, while “Magome-juku” features stone-paved slopes along a hillside, with more shops and local snacks. Narai is located in the northernmost area and is close to Matsumoto, making it suitable to combine with a Matsumoto itinerary. Magome and Tsumago are located in the south, about 8 kilometers apart, and are connected by a popular hiking trail. If you have limited time and want to experience the most complete historic street scenery, Narai-juku is highly recommended as the first choice.
3. Can luggage be stored at Narai-juku?
Narai Station is relatively small, and the number of coin lockers is limited. It is strongly recommended to travel light. Travelers carrying large luggage can store it at major stations such as Matsumoto Station or Nagoya Station, or use luggage delivery services to send baggage directly to their accommodation, making it easier to stroll through the old streets.
4. Can credit cards or electronic payments be used in Narai-juku?
Some shops and facilities accept credit cards or electronic payments, but many small stores still only accept cash. It is recommended to prepare some Japanese yen in advance. In addition, transportation IC cards such as Suica cannot be used on the Chuo Main Line section between Shiojiri and Nakatsugawa, so please pay special attention when taking trains.
5. Are there bears around Narai-juku? Should visitors be concerned?
Narai-juku is surrounded by mountains, and there have occasionally been reports of bear sightings in nearby forest areas such as Torii Pass. However, visitors walking within the old street area generally do not need to worry. If you plan to hike mountain routes such as Torii Pass, it is recommended to carry a bear bell, avoid entering forests alone at dawn or dusk, and check local bear sighting information in advance.
6. Are there any seasonal events in Narai-juku? Which season is the best time to visit?
The “Narai-juku Ice Candle Festival” is held every year on February 3 during Setsubun. Approximately 2,000 handmade ice candles are placed along the old street, along with the lighting of two hundred Jizo statues and fireworks, creating a dreamlike winter scene. However, winter nights are extremely cold, so visitors should prepare adequate warm clothing. Overall, spring with fresh greenery and autumn with colorful foliage are the most recommended seasons to visit, as the weather is pleasant and the mountain scenery is beautiful. Regardless of the season, because the altitude is approximately 940 meters, temperature differences between day and night are significant, so layered clothing is recommended.
