Hachimanbori

Hachimanbori is a historic waterway located in Omihachiman City, Shiga Prefecture, and was built during the Azuchi-Momoyama period by Toyotomi Hidetsugu, the nephew of Toyotomi Hideyoshi. In 1585, when Hidetsugu constructed Hachiman-yama Castle, the moat was excavated to serve the castle’s defensive functions and support the development of the castle town, and it was maintained as an important canal connecting Lake Biwa and the castle town.

This moat stretches for approximately 4.7 kilometers, winding around Mount Hachiman and linking to inland lakes such as Nishi-no-Ko as well as Lake Biwa. At the time, a system was established to have cargo boats traveling on Lake Biwa stop at Hachiman, and it functioned as the “lifeline of the town,” bringing together people, goods, and information. Thanks to this water transport, commerce developed greatly, and it became an important foundation supporting the growth of the Omi merchants. Omihachiman flourished as one of the central bases of the Omi merchants and played a role in supporting the activities of merchants who expanded their business across Japan.

Throughout the Edo period, Hachimanbori prospered as a hub of logistics, and the town of Omihachiman was as lively as Otsu. Along the moat, white-plastered storehouses and merchant houses line the banks, conveying the prosperity of that era to the present day. In addition, many historical structures remain in the surrounding area, including Himure Hachimangu Shrine, Hakuun Bridge, the former Nishikawa Residence, and the former Ban Family Residence, allowing visitors to strongly sense the atmosphere of the castle town.

However, although Hachimanbori continued to play an important economic and distribution role until around the early Showa period, it gradually lost its function after the war due to the development of land transportation such as railways and roads. Eventually, the moat fell into disrepair, its water quality deteriorated, and it became so neglected that there were even plans to fill it in.

Under these circumstances, conservation and restoration efforts led by local residents, especially young people, began, and cleaning and landscape improvement were carried out. Thanks to these efforts, Hachimanbori regained its beautiful former appearance and is now highly regarded as a historic landscape. The surrounding area has also been designated as an Important Cultural Landscape by the national government, making it a representative tourist destination in Omihachiman.

Today, Hachimanbori is known for its atmospheric scenery, where white-plastered storehouses and old merchant houses are reflected on the water’s surface, and it is also widely recognized as a filming location for period dramas and movies. In particular, the area around Hakuun Bridge to Meiji Bridge is often used for filming. Another major attraction is its seasonal natural beauty: cherry blossoms and irises in spring, lush green willows in summer, autumn foliage in fall, and snowy scenes in winter offer visitors a different ambiance each time they come.

In addition, the “Hachimanbori Meguri” boat tour on traditional Japanese boats is very popular. During the approximately 30-minute cruise, visitors can leisurely admire the historic townscape from the water and enjoy a truly exceptional experience. The boatman’s guidance, the sound of the oars, and the gentle sparkle of the water’s surface provide deep relaxation and moving moments for all who visit.

In this way, Hachimanbori stands as a symbol of the region’s history and culture, from the formation of the castle town and the rise of the Omi merchants to the present day. Along with the charm of a waterside town, it is a precious place where one can experience more than 400 years of accumulated history.
