Uzu no Oka Onaruto Bridge Memorial Museum

The Uzu no Oka Onaruto Bridge Memorial Museum opened in 1985, the same year the Onaruto Bridge connecting Awaji Island and Shikoku began operations. The facility was established as a complex to commemorate the bridge construction and to showcase the region's connection between Awaji Island and Tokushima Prefecture. Today, it serves as both a cultural landmark and a rest stop that celebrates Awaji Island's most famous agricultural product: onions.

The museum sits on a hilltop at the southernmost tip of Awaji Island, offering panoramic views of the Naruto Strait and its famous whirlpools. The site has become known for its quirky onion-themed attractions, most notably the giant onion sculpture that serves as a popular photo spot. Inside, the Uzushio Science Museum features exhibits on the formation mechanism of the Naruto whirlpools, recognized as one of the world's three major tidal currents. The museum includes interactive displays such as hydraulic models demonstrating whirlpool formation, digital art recreating underwater scenes, and the Uzunetarium, which requires a separate admission fee.

Visitors can experience several unique attractions at the complex. The onion catcher game costs 500 yen for five attempts, and participants receive onions regardless of whether they win. Free onion wigs are available for rental for photos with the giant onion sculpture or on the renovated wooden deck terrace. The facility also houses a street piano wrapped in student artwork from a local elementary school that closed in 2020. The second-floor restaurant with views of the Onaruto Bridge serves regional cuisine featuring Awaji Island ingredients, including the Awaji Island Onion Beef Burger, which won first place in the National Gotochi Burger Grand Prix. The ground floor burger kitchen and souvenir shop offer additional local products and specialties.

Admission to the main memorial hall is free. The Uzunetarium within the Uzushio Science Museum charges 300 yen for adults and 100 yen for elementary through high school students, with preschool children entering free. The facility is wheelchair accessible and includes barrier-free restrooms. Free parking accommodates 200 cars, though buses require advance reservation. The museum is located approximately five minutes from the Awajishima-Minami Interchange on the Kobe-Awaji-Naruto Expressway. Visitors can also reach the site via the Awaji Bus, disembarking at Fukura stop for a short walk to the museum. A free shuttle bus service called UZU LOOP connects attractions in southern Awaji Island.
