14 tanks shows the positional relationship of the Pacific Rim

Kaiyukan is the characteristic institution in the Tempozan harbor village. After you enter the entrance gate, you will walk through the tunnel tank called “Aqua gate” (魚のとおりぬけ・アクゲート) . 
Next zone is called “Japan Forest” (日本の森). Suggested route shows us a hydrologic water cycle, which means the water coming from this forest falls into the river, and the water goes to sea and into the deep sea.
At the middle of the aquarium, whale shark and ray swims in the “Pacific Ocean” tank (太平洋水槽) which is about 9.8yd(9m) deep. When the whale shark about 5.5yd(5m) long comes near to you, you will see them with eyes open.
On the north side of the aquarium, tank represents “The Aleutian Islands” (アリューシャン列島) where sea otters live.
On the south side of the aquarium, tank represents “Antarctica”(南極大陸) where king penguins(オウサマペンギン) live.
On the west side of the aquarium, California sea lion(カリフォルニアアシカ) swims in the tank which represents “Monterey Bay”(モンタレー湾).
