Insider tip — Yu-A-Port at Mikuni Onsen serves the historic port town of Mikuni in Sakai City — the most important Hokuriku coastal harbor of the Edo period whose merchant ships carried Echizen rice, lacquerware, and washi paper to Osaka on the kitamaebune coastal trade route. The Mikuni lighthouse of 1876, one of Japan first Western-style lighthouses built with French technical assistance, still guides vessels through the Kuzuryu River estuary into Mikuni harbor, and the Mikuni Festival seven-storey bamboo-frame samurai warrior figures are designated a National Important Intangible Folk Cultural Property.
