In the late 7th century, the "Tōsandō" region were identified as one of the eight largest administrative areas of the Imperial system ("ritsuryo seido").
"Gokishichidō" is an ancient system of names for parts of the country, including "Tōsandō". "Tōhoku" covers the northern area of the island of Honshū in roughly the same area as the traditional "Tōsandō".
In the Meiji period, the modern regional system was made by Imperial decree. Japan was divided into regions ("chihō "), including the Tōhoku region. A regional council ("chihō gyōsei kyōgisai") was headed by the governor of the most powerful prefecture in the regional grouping. The council also included regional chiefs of central government ministries.
Over time, Tōhoku has developed its own regional dialects, customs and unique traditional culture. Tōhoku is famous for farming. Now a lot of kinds of vegetable are grown.
The Tōhoku University was built in 1907.
