Enjoy time travel and slip back to the Edo Period. Tsumago is the first area designated as a national preservation district of important traditional structures.
"The entire Kisoji is in the mountains" - this is the first phrase of a famous novel, "Yoakemae (Before the Dawn)," written by Toson Shimazaki, a leading writer of Japanese modern literature. Both Tsumago and Magome served as post stations located on the Nakasendo Route, which is one of the five routes that connected Edo (current Tokyo) and locals in the Edo Period. The Nakasendo linked Edo and Kyoto through the inland area and had 69 post stations. Tsumago was the 42nd station while Magome was the 43rd, adjacent to the Kisoji Route of many mountains and woods.
If you walk through these two post station towns, you will feel as if you went back to the Edo Period of 300 years ago. The area is already well known internationally as a place that retains the atmosphere of old Japanese post stations and welcomes a number of overseas tourists. Hiking the Nakasendo is especially popular among foreign visitors, as they can experience the atmosphere of the Edo Period while walking through the route.
In Tsumago, there is an officially appointed inn "Wakihonjin Okuya." The current building was reconstructed in 1877, using a plenty of Japanese cypress, whose use was actually prohibited in those days. Furthermore, "Honjin," a town director's house restored in 1995, and other historical structures are there to reproduce the views of the town from the late Edo Period.
When you walk from Tsumago through the Magome-toge Pass to O-tsumago, where you can still feel the atmosphere of a rustic post station town, you will be surrounded and astonished by the dense lines of cedar and Japanese cypress standing on the both sides of the path, making you feel that you are "in the mountains" indeed. Descending from the peak of the Magome-toge Path of 790 meters high, you will arrive at Magome after walking about nine kilometers in about two and a half to three hours. This is the perfect course for hiking the Nakasendo, the street of history.
