Kaikyokan Aquarium: Shimonoseki's World-Class Marine Showcase

Encounter the world's largest collection of live fugu and walk through a tunnel beneath circling sharks at Kaikyokan — Shimonoseki's landmark aquarium built into the dramatic Kanmon Strait shoreline.

What to expect

Step into the Kanmon Strait Tunnel Tank and watch rays and sharks glide overhead as container ships thunder past above on the water outside — a surreal juxtaposition of the natural and maritime worlds. The fugu gallery showcases dozens of species of puffer fish in elaborate species-specific tanks, from the thumbnail-sized to the basketball-sized, their inflated forms absurdly majestic. The penguin zone and Irrawaddy dolphin pool delight at every age, while the panoramic observation deck frames one of Japan's busiest sea lanes against the Kyushu hills. Allow two to three hours to do it proper justice.
