During the Edo Period (1603 – 1868), post towns were built and used throughout Japan. Post towns served as a resting and lodging spot for travelers, and were located on major routes connecting Edo (present day Tokyo) with other significant cities throughout the country.

Nakasendo is one of the “Edo Five Routes”, and connected Edo with Kyoto by going through central Honshu. Some of the post towns on Nakasendo remain today, and retain the Edo period atmosphere. Here are 5 post towns on the Nakasendo Route that you can visit.

What are the Edo Five Routes? ("Gokaido")

The "Edo Five Routes" or "Gokaido" were a web of five land routes connecting Edo, the capital city, with other prominent cities in Japan. The five routes are as follows:

・The Tokaido Route: Edo to Kyoto (along the coast)
・The Nakasendo Route: Edo to Kyoto (inland)
・The Koshu Kaido Route: Edo to Kai Province (current Yamanashi prefecture)
・The Oshu Kaido Route: Edo to Mutsu Province (current Fukushima prefecture)
・The Nikko Kaido Route: Edo to Nikko Toshogu Shrine

The routes were used for travel, and especially to facilitate the "sankin-kotai" policy. The policy forced daimyo, or local feudal lords, to spend a few months every year in Edo. This helped the Edo central government maintain their power over daimyo and to establish better communication with them.

What are Post Towns?

Post towns, called shukuba (宿場) in Japanese, were station-like rest stops built on the travel routes. These post towns had accommodation, shops and more, to give travelers well-needed rest during their long voyage. Just counting those along the Edo Five Routes, there were over 200 such post towns.

The post-towns were built to perform a defensive function for its visitors and inhabitants, with the "masu-gata" construction of their entrances. This was a strategic construction that curved the city's approach in a sharp right angle, thus lagging the attackers and buying time for the defenders to cull their numbers.

About Nakasendo

Nakasendo is one of the Five Edo Routes. While the Tokaido Route follows the eastern coast of Japan from Edo to Kyoto, the Nakasendo Route cuts through Honshu to reach Kyoto.

The route goes through present day Saitama, Gunma, Nagano, Gifu, Shiga and Nagano prefectures. Nakasendo was also called the “Kiso Route”, since it went through the Kiso region in Nagano. On the 540-km route, there were 69 post towns in total. This is the most number of post towns that any of the Edo Five Routes has.

Traveling the Nakasendo Route: 5 Post Towns of the Edo Period

Though many of the post town became unused and dismantled, some still remain to this day. Here are five post towns that continue to preserve parts of their Edo period townscapes. Changing their function from rest-stops to modern-day inheritors of old sceneries, the post towns continue to attract travelers in their role in tourism.

Many other post towns have goheimochi, but each of them tends to have their own unique sauce. In Narai-juku, the goheimochi from Tanakaya is popular.



Another popular snack from Narai-juku is Oyaki. Oyaki originated in the Narai region, and is a steamed bun with savory fillings (usually pickled vegetables). In Narai-juku, you can find a Oyaki specialty shop called Tezukara.

Toson Memorial Museum

Magome-juku is where the famous Japanese writer Shimazaki Toson was born and spent a large portion of his childhood. In honor of him, the Toson Memorial Museum was built in the area. You can find over 6,000 documents and materials relating to Shimazaki Toson.

These small flowers, called baikamo, are a popular sight at Samei-juku. They only blossom in areas with clean water, and look like small plum blossoms.

You can see the baikamo flowers between mid July and late August. From late July to early august, lights are set up in the river by the baikamo, creating ethereal scenery.

There is a legend behind Isame no Kiyomizu, the source of the river. It is said that the legendary Japanese prince, healed his wound with the waters from Isame no Kiyomizu.

The soy sauce made using the clear waters of Samei is a popular souvenir. At Yamaki Shoyu, you can buy soy sauce and other products made from Samei’s waters, such as miso. You can even try shoyu soft serve – a vanilla soft serve with a drizzle of soy sauce.
