Maihara (米原町 Maihara-chō) was a town located in Sakata District, Shiga, Japan.
On February 14, 2005 Maihara was merged with the towns of Ibuki and Santō, all from Sakata District, to form the new city of Maibara.
In 2003, the town had an estimated population of 12,212 and a density of 285.46 persons per km². The total area was 42.78 km².
It has developed as a traffic junction. In Edo period, there were Samegai-juku and Banba-juku. In Meiji period, a large station opened here, but it was named Maibara, not Maihara. So many Japanese mistook the town's name and the station's name. Eventually Maibara was adopted as the official name of new city.
