Toyama Bay rapidly plummets to incredible depths near the coast, to a maximum depth of 1,250 meters. At a depth of 200 meters, the water is about 10°C, but from 300 meters down to the bottom, you'll find what is known as Japan Sea Proper Water, which is just 1–2°C.

Small and medium-sized temperate-zone fish that live in Toyama Bay's surface layer can be seen in these tanks. Of particular note is the pinecone fish, whose glow was discovered at the original Uozu Aquarium during a blackout one night in 1914.
