The tea wholesale district emerged in the Kamikoma area thanks to its locational advantage as a transport node in the Kizu River water transportation system. The tea wholesalers constructed about 40 buildings from the end of the Edo Period through the Meiji, Taisho, and erly Showa Periods. These structures still line the street, which has been dubbed "tea wholesalers street." In 2004, a monument to the Yamashiro tea business was built to commemorate the 120th anniversary of the founding of the Yamashiro Tea Business Union.
