Shimonoseki's marine science museum is the best place to see fugu (pufferfish) up close without the risk. The world's largest fugu exhibit holds hundreds of the creatures, and the building itself makes an impression — you enter through a whale skeleton suspended overhead. Exhibits cover the rich marine life of the Kanmon Strait, one of the world's busiest shipping channels and a surprisingly productive fishing ground.
