Things to Expect at the Churaumi Aquarium of Okinawa, Japan

Being a country made up of several islands, a lot of Japan’s historical and cultural properties have ties with the sea. In fact, various structures built in recent years still pay proper tribute to the oceans in one way or another.

Among the most popular places with this association are aquariums, which are practically scattered all throughout Japan. These tourist attractions usually vary in terms of size, theme, and design but all share the same goal of informing the public of local and international aquatic habitats.

Those heading to Okinawa Island are in for a treat, as it houses the best aquarium in Japan – the Churaumi Aquarium.

Overview of the Churaumi Aquarium of Okinawa, Japan

Back in the year 1975, Okinawa housed a popular attraction known as the Ocean Expo Park, which was recognized on a global scale. Unfortunately, as more and more establishments of the same kind started popping up at different cities of Japan, the Ocean Expo Park soon lost its fame and faded into the background.

The local government decided that a complete change had to be done in order to boost tourism once more, resulting in the design and construction of the Churaumi Aquarium.

Yukifusa Kokuba served as the brains behind the project and was able to successfully revamp the property with a modern touch, all the while maintaining its marine encounter theme. The Churaumi Aquarium opened its gates to the public on the 1st day of November during the year 2002.

The aquarium’s name was chosen by the public and can be broken down into two words – chura and umi. When translated into English, the term “chura” means graceful or beautiful, while the term “umi” is used to refer to the ocean.

Sitting on a 19,000-square meter land, the Churaumi Aquarium houses a total of 77 tanks. These tanks contain various marine life including tropical fish, coral, sharks, and deep sea creatures. At present, an estimated total of 26,000 animals is taken care of at the aquarium.

Keeping in line with the aquarium’s focus on exploring the deep seas, the building itself is designed in such a way that visitors enter through the third floor and have to make their way up to the fourth floor to begin their descent, one floor at a time.

Each floor at the Churaumi Aquarium revolves around a central theme, i.e. the Invitation to the Great Sea, the Journey to a Coral Reef, the Journey to the Kuroshio, and the Journey into the Deep Sea.

Churaumi Aquarium’s Invitation to the Great Sea 

The fourth floor of the Churaumi Aquarium is known as the Invitation to the Great Sea. Here, visitors are welcomed with the island’s beautiful cobalt blue ocean and dazzling lights. Some notable points of interest in this section include:

The Whale Shark Sculpture is the very first thing that greets visitors before they enter the Churaumi Aquarium. This place serves as a great photo backdrop for tourists, given the Okinawa Churaumi Aquarium sign located behind the whale sculpture.

Uminchu Gate

A short walk after passing the Whale Shark Sculpture, visitors will come across the Uminchu Gate. Uminchu literally translates to mean fisherman in English which is exactly what any visitor will feel like upon seeing the breathtaking view of the ocean from this section.

The entrance to the Churaumi Aquarium can be located by taking the escalator down to the 3rd floor and searching for it on the right side.

Inoh Restaurant

Churaumi Aquarium’s Journey to a Coral Reef 

One floor down from the Invitation to the Great Sea, visitors are welcomed into a colorful underwater world known as the Journey to a Coral Reef. Here, people are free to look, touch, and experience the different types of marine life associated with the coral reefs housed at Churaumi Aquarium, as well as several freshwater habitats of Okinawa.

The Journey to a Coral Reef can be broken down into six main sections:

Life in the “Inoh”

The term “Inoh” is used to refer to shallow bodies of water that feature coral reefs. As such, this section focuses on creatures that live in such habitats.

Some of the marine life that can be found here include sea cucumbers and various kinds of starfish. At present, an estimated total of twenty species is housed at the exhibit, which is composed of 9.5 cubic meters of water. Visitors may touch any and all of these creatures, as long as they are handled gently and with extra care.

The Coral Sea

The Coral Sea refers to a massive exhibit that consists of a tank with an open top. This section features a wide array of coral reefs, all of which have been properly cultivated through a sophisticated system that allows the continuous supply of fresh water into the Churaumi Aquarium from the sea.

An estimated total of eight hundred colonies made up of over fifty types of coral reefs is housed at the exhibit. A big percentage of these corals have been part of The Coral Sea since the opening of the Churaumi Aquarium, growing at a steady pace for nearly fifteen years.

The Sea of Tropical Fish

The Sea of Tropical Fish serves as a representation of the Okinawan sea and its stunning coral reefs. The 700-cubic meter water tank houses various tropical fish, as well, which are well taken care of within a near-natural habitat.

Coral Reef World

The Coral Reef World focuses on providing the public with a detailed explanation of the different creatures that can be found near coral reefs, particularly those that pose dangerous threats to unsuspecting humans.

Comparisons using models and living specimens are displayed at the exhibit to better explain the nature of these creatures and how certain situations should be dealt with to avoid unnecessary conflict.

Coral Reef Gallery

For those who want to have a closer look at each of the different creatures associated with coral reefs, the Coral Reef Gallery houses about thirty water tanks that range from small to large sizes. Each of these tanks houses one form of marine life and includes a brief overview.

Freshwater Life

The Freshwater Life, as implied, houses a variety of freshwater creatures, particularly those that can be found in Okinawa’s rivers.

Churaumi Aquarium’s Journey to the Kuroshio 

At the second floor of the Churaumi Aquarium, the Journey to the Kuroshio can be located which introduces visitors to the dynamic world of migratory fish. The floor consists of the following exhibits and facilities:

Churaumi Theater

Churaumi Aquarium’s Journey into the Deep Sea

Last but certainly not the least, the Journey into the Deep Sea located at the first floor of the Churaumi Aquarium completes the entire trip by transporting visitors into a recreated Deep Sea World consisting of the following sections:

Deep Sea World

The Deep Sea World is best described to be a quiet world that experiences no sunlight. It houses various deep-sea creatures that have been carefully collected from over two hundred meters below the surface of Okinawa’s waters.

Small Life in the Deep Sea

As implied by its name, this section introduces visitors to the tiny creatures living in the deep sea which usually go unnoticed.

Deep Sea

The Deep Sea exhibit features various marine creatures that are considered to be rare and live two hundred meters below the surface, if not more. Some animals to expect here include the ruby snapper and the blacksail snake mackerel.

Ocean Planetarium

The Ocean Planetarium is aptly named for the extensive collection of star-like creatures it houses which give the tank an outer space look.  Everything is made more magical through the use of ultraviolet rays which reflect wonderfully on the coral reefs.

Aqua Lab

The Aqua Lab serves as a place where visitors can get more knowledge about marine life through easy-to-understand lectures and videos. The topics tackled at the laboratory change on a daily basis so it is best to check the official website of the Churaumi Aquarium prior to one’s visit.
