Omihachiman is a city in Shiga Prefecture, located on the east side of the largest fresh water lake in Japan, Lake Biwa. Omihachiman is famous as the birthplace of the Omi merchants. Omi merchants (Hachiman merchants) were businessmen who were active throughout Japan, especially during the Edo period (1603-1867) in Tokyo and Hokkaido. Their busness was based on trust. Therefore, they did not loan money at high interest or otherwise take advantage of supply shortages. Their business policy was to meet the needs of the people and to create a business that people could respect. The residential areas these merchants once lived in, have been preserved as nationally important historic buildings. These areas are the main tourist spots in Omihachiman.

Economic Development

There are several factors that contributed to the development of Omihachiman. One major factor was the Hachiman Moat. It was orginally built to protect a castle, however in the 1580’s, Hidetsugu Toyotomi transformed the moat into a canal system and forced boats using Lake Biwa to stop in Hachiman. It became an active trade center, and served as a catalyst for Omi Businesses. Omihachiman has many specialities and souvenirs that are made from their abundant natural resources and are a product of the long history. Omi beef and rice are the most important agricultaral products. Fresh water pearls, manufacturing of prayer beads and shoes are also famous.

The Sagicho Matsuri festival held in mid-March is one of Shiga’s most famous festivals.
