Tucked along the shores of Lake Biwa in Shiga Prefecture lies the historic town of Omi Hachiman, a rare example of a Japanese castle town that transitioned into a prosperous merchant hub and preserved its rich cultural and architectural heritage.
With its network of Edo-era canals, beautifully preserved merchant homes, and a long-standing legacy of Omi merchants and Western-Japanese architectural fusion, Omi Hachiman offers visitors a living museum of history, commerce, and community pride.
A Brief History of Omihachiman

- Founded in 1585 by Toyotomi Hidetsugu under orders from his uncle, Toyotomi Hideyoshi
- Developed as a commercial center following the abandonment of nearby Azuchi Castle
- Became a toll- and regulation-free merchant town, encouraging growth and prosperity
- Hachimanbori Moat constructed to facilitate both defense and trade
- Survived the Meiji Restoration due to local effort and geographical importance
Though originally built as a strategic castle town under Hidetsugu, nephew of Toyotomi Hideyoshi, Omi Hachiman’s true legacy was forged through commerce, not conquest. After Hachimanyama Castle was abandoned in 1595, the town evolved into a thriving center of trade thanks to its access to Lake Biwa and its location along the Nakasendo Road.
Local merchants—known as Omi shonin (Omi merchants)—spread their goods and principles across Japan, helping transform Omi Hachiman into a nationally significant economic hub.
Hachimanbori Moat: "The Venice of Japan"


The Hachimanbori Moat, a 4.7 km-long artificial canal, remains the beating heart of the town. Lined with white-walled storehouses, merchant residences, and charming wooden bridges, the canal served a dual purpose as both a defensive barrier for the now-vanished Hachimanyama Castle and a trade route connecting the town to Lake Biwa and beyond.
- Built: Late 16th century
- Length: Approx. 4.7 km
- Function: Defense, transportation, and commerce
- Today: A highlight of the town’s preservation district; scenic boat cruises available
Thanks to community activism in the 20th century, the canal was saved from being filled in and is now part of the Omi Hachiman Important Preservation District for Traditional Buildings.




Today, visitors can take a cruise through the merchant town and see the Edo-Era constructions just as they would have looked some 400 years ago. The town is particularly beautiful in spring as the cherry blossoms frame the bridges and canals throughout the city. Movie lovers may find the sights familiar as this location is often used in historical dramas and films.
The region is also well known for Omi-beef—one of the most highly regarded and the oldest brand of wagyu in Japan, as well as kawara roof tiles—decorative roof tiles often depicting the face of an ogre or lion seen across Japan.
