Nakasendō
The Nakasendō, also called the Kisokaidō, was one of the centrally administered five routes of the Edo period, and one of the two that connected the de facto capital of Japan at Edo to Kyoto. There were 69 stations between Edo and Kyoto, crossing through Musashi, Kōzuke, Shinano, Mino and Ōmi provinces of Japan|provinces]. In addition to Tokyo and Kyoto, the Nakasendō runs through the modern-day prefectures of Saitama, Gunma, Nagano, Gifu and Shiga, with a total distance of about.
Unlike the coastal Tōkaidō, the Nakasendō traveled inland, hence its name, which can be translated as "中 = central; 山 = mountain; 道 = route". Because it was such a well-developed road, many famous persons, including the haiku master Matsuo Bashō, traveled the road. In the late 1830s Hiroshige also walked the Nakasendo, contributing 46 designs to a series of 69 views of the Nakasendo, which was later completed by Keisai Eisen.
Many people preferred traveling along the Nakasendō because it did not require travelers to ford any rivers.
In Gunma Prefecture, the Nakasendō is featured on the 'na' card in Jomo Karuta.
Pre-Nakasendō
Ritsuryō
Around the beginning of the seventh century, during the beginning of Ritsuryō, the area that would eventually make up the Nakasendō was developed to connect Kinai with the provinces of the Tōsandō that lie to the east.Sengoku period
During the Sengoku period, which lasted from the 15th to 17th centuries, the Tōsandō was controlled by the Takeda, Ogasawara, Kanamori and Oda clans. In order to connect the Tōsandō with the Tōkaidō, a road system was developed. This route is generally followed by the modern day national highways numbered 52, 151, 153, and 22.Creation of the Nakasendō

Among them was the rejuvenation of Japan's thousand-year-old highway system. Five roads were formally nominated as official routes for the use of the shōgun and the other daimyō and to provide the Tokugawa shogunate with the communications network that it needed to stabilize and rule the country. One of these five roads was the Nakasendō, which stretched from Edo, from where the shogun wielded the real power, through the central mountain ranges of Honshu and on to Kyoto.
Until the establishment of these formal trade routes, many shorter routes had existed, connecting towns over various distances. For example, the Kisoji route's eleven post towns all become part of the Nakasendō. Prior to the Edo period, the route had been called both "Sandō" and "Tōsandō". During the Edo period, the name was changed to Nakasendō and was written as both 中山道 and 中仙道, but the Tokugawa shogunate established 中山道 as the official name in 1716.
Today
Although much of the Nakasendō no longer exists in its historic form, its route is now roughly followed by modern roads. In order, they are:- National Route 17: Tokyo to Takasaki
- National Route 18: Takasaki to Karuizawa
- National Route 142: Saku to Shimosuwa
- National Route 20: Shimosuwa to Shiojiri
- National Route 19: Shiojiri to Ena
- National Route 21: Mitake to Maibara
- National Route 8: Maibara to Kusatsu
- National Route 1: Kusatsu to Kyoto
