HistoryThe area of present-day Itoigawa was part of ancient Echigo Province. Historically, Itoigawa lies at the end of the shio no michi (salt road) that supplied salt from the Sea of Japan to Edo via Shinano Province. During the Edo period, Itoigawa was the castle town for Itoigawa Domain. After the Meiji restoration, with the establishment of the modern municipalities system on April 1, 1889, Itoigawa became a town within Nishikubiki District, Niigata. The modern city was created on June 1, 1954 when the former town of Itoigawa absorbed the villages of Uramoto, Shimohayakawa, Kamihayakawa, Yamatogawa, Saikai, Ōno (Daino), Nechi and Kotati (Otaki) to elevate city status. On April 1, 2005, the towns of Nō and Ōmi (both from Nishikubiki District) were merged into Itoigawa. Oldest known jadeite-using cultureA great many jadeite beads and axe heads as well as the remains of jadeite workshops from the Neolithic era have been uncovered in Itoigawa. These beads and axes were traded throughout Japan and the Korean Peninsula and were produced by the world's oldest known jadeite-using culture, centered on the Itoigawa region.[6][7] GovernmentItoigawa has a mayor-council form of government with a directly elected mayor and a unicameral city legislature of 20 members. Itoigawa contributes one member to the Niigata Prefectural Assembly. In terms of national politics, the city is part of Niigata 6th district of the lower house of the Diet of Japan. EconomyCommercial fishing and the production of limestone and cement are the mainstays of the local economy.
