Shimonoseki is the primary hub for pufferfish consumption in Japan, reflected in the aquarium's specialized pufferfish research and exhibition department.
The aquarium's 'Penguin Village' contains an underwater viewing area where penguins swim directly above the heads of visitors.
The facility maintains a research partnership with the local university to study the migratory patterns of marine life in the Kanmon Strait.
The main tank uses water pumped directly from the turbulent Kanmon Strait to support local marine biodiversity.
The exhibit includes a significant collection of skeleton specimens of marine mammals, including a large blue whale model.
Kaikyokan is a major public aquarium located on the waterfront of Shimonoseki, a city world-renowned for its pufferfish industry. The facility features over 100 species of pufferfish, representing the largest collection of its kind globally. A signature exhibit includes an underwater tunnel where visitors view sea creatures from the Kanmon Strait. The aquarium hosts a regular dolphin and sea lion performance stage that overlooks the Kanmon Strait itself. Its penguin village is highly specialized, focusing on the ecology and breeding of Humboldt penguins in a naturalistic outdoor setting. The architecture centers around a multi-level layout that concludes near the coastline, integrating the marine environment of the surrounding strait into the visitor experience.

Check the daily schedule upon arrival to coordinate your visit around the dolphin and sea lion performance times.
Allow extra time to observe the penguin feeding sessions, which are held at specific intervals throughout the day.
Visit the gift shop for unique pufferfish-themed merchandise that is difficult to find elsewhere in Japan.
Do not attempt to see every exhibit in a rush; prioritize the pufferfish section and the penguin village as they are the primary highlights.
Refrain from using flash photography, as it can startle the marine animals and disturb their exhibits.
