Overview (history, characteristics, attractions)

Shimonoseki Kaikyokan is a large aquarium facing the Kanmon Strait in Shimonoseki City, Yamaguchi Prefecture. It introduces the diverse marine life that inhabits the Kanmon Strait, the Seto Inland Sea, and the Sea of Japan, and was developed as a place to deepen understanding of the region's marine resources and environmental conservation. The aquarium's unique feature is that visitors can experience the marine ecosystem through dolphins, sea lions, penguins, and a touch pool, focusing on creatures that live in the local seas. The exhibits also allow visitors to experience the fascinating currents of the Kanmon Strait and seasonal migratory fish up close, making it a popular tourist destination.
