Shibukawa Marine Aquarium

This historic museum themed around the Seto Inland Sea opened in Showa 28 (1953) and consists of an aquarium and an exhibition hall.
The aquarium displays approximately 2,000 marine animals from around 180 species found throughout Japan, primarily in the Seto Inland Sea, in 34 tanks of various sizes. It is one of the few places in Japan where visitors can see fish species closely associated with the region, including the Japanese sand lance, known as a herald of spring in the Seto Inland Sea, and the Japanese sardinella, commonly called mamakari.

The exhibition hall consists of three galleries showcasing approximately 1,000 shell specimens. Although the collection is relatively small, it includes many rare species and offers plenty to see. Ship models and mounted fish specimens are also on display.

The outdoor area is home to marine animals such as lively northern fur seals, charming spotted seals, and sea turtles. The displays of full-size maritime equipment are also worth seeing. A particularly notable exhibit is the full-scale lighthouse replica built in Showa 28 (1953) to commemorate a visit by Emperor Showa and the Empress. Known as Miyuki Lighthouse, it has become the symbol of the museum.
