The Nakasendo Way has 69 Post-Stations, 12 of them are on the Kisoji road.
The Nakasendo Way 中山道 is a 500km road connecting Tokyo and Kyoto. Travelers hundreds years ago used to take this route and walked all the way to Kyoto from the starting point Nihonbashi (near Tokyo. Station) in Tokyo. While it is of course impossible to walk all the way within days, travelers had to stop at villages to be served accommodation or meals, and these villages on the Nakasendo were developed as 69 post-stations being an oasis for travelers.
Though many of the 69 post-stations have transformed into a town or a city with modern buildings now, some stations deep in the mountains were left behind with old buildings, fortunately, and the nostalgic townscape has been restored there. The restored 12 post-stations are situated on the Nakasendo Way between Shiojiri and Nagoya, where the Kisoji road 木曽路 is.

The Chuo Honsen(Main) Line runs along the Kisoji area
Most part of the Nakasendo Way itself has remained to this day, some parts have even developed as a national road. Also, the Chuo Honsen Line linking Tokyo to Nagoya runs along the Kisoji road on the Nakasendo Way. Taking the Tokaido Shinkansen Line along the coastline is much quicker way of transport between Tokyo and Nagoya, however, taking the Chuo Honsen Line allows you to visit the Kisoji area to discover good old Japan, different from what you see in Kyoto or those famous tourist spots.
The Kisoji area on the Nakasendo Way lies at the foot of the Central Japan Alps on the west side and includes 12 post-stations - 1.Niekawa-juku, 2.Narai-juku, 3.Yabuhara-juku, 4.Miyanokosi-juk. 5.Kiso Fukushima-juku, 6. Agematsu-juku, 7.Suhara-juku, 8. Nojiri-juku, 9.Midono-juku, 10. Tsumago-juku, 11.Magome-juku and 12.Ochiai-juku, where old Japanese buildings have been restored with nostalgic townscapes.
The three of the 12 post-stations; Narai-juku 奈良井宿, Tsumago-juku 妻籠宿 and Magome-juku 馬籠塾 are a well noted sightseeing spot for its picturesque scenery. There are tourist information offices and accommodations there. The accommodations are Japanese inns in traditional style.
