The Kanei Tsuho is a Japanese coin that is comparable to Joseon’s Sangpyeong Tongbo in that it was issued in larger amounts and in more types than any other coin, and was circulated for the longest period in the history of Japanese currency. The coin was issued in local mints across Japan for about 240 years from 1626, the 3rd Kanei year in the Tokugawa Shogunate period, to 1868 and was used widely by the common people of Japan. The front face of the coin is inscribed with four Chinese characters representing its name, Kanei Tsuho (寬永通寶), while its rear face contains inscriptions of the name of the area, a decorative design, numbers and characters.
