Historical streetscape of Onyu spreads along the road at the junction of Waka-kaido Road and Harihatagoe also known as Negori-zaka slope. In the surrounding area of Onyu district stand Wakasahime Shrine, Wakasa Kokufu, and Wakasa Kokubunji Temple. This is the area where dedicated articles and salt were sent to Kyoto, the ancient capital of Japan. A market was established here after medieval times and developed into a town in front of Wakasahime Shrine. Before Kumawaga-juku was developed, it used to be the base of transportation of Saba-kaido Road, or a highway supplying marine products and fish such as mackerel called “saba” in Japanese to the Imperial family and court in Kyoto, the ancient capital of Japan. In the mid Edo Period, Onyu district flourished by processing agate in Hokkaido and Tohoku region brought there by Kitamae-bune, or freight vessels by way of the Japan Sea. A large quantity of agate called Wakasa agate processed in Onyu was shipped to Kyoto and Osaka. Processing of agate has been handed down as a traditional craft up to today.
Today Tango-kaido Road and the area close to Wakasahime Shrine are lined with houses called Machiya, or merchants’ houses, which retain traditional architectural style built after the Meiji Period. In Onyu Festival, an annual festival of Wakasahiko shrine and Himegami shrine, drum dance and Kagura drum performance are dedicated to the gods of these shrines by local residents and Ujiko, or shrine parishioners. Kagura refers to sacred Shinto music and dancing performed at a shrine.
