Sumida Aquarium – The Best Aquarium in Tokyo!



Sumida Aquarium is located directly under the Tokyo Skytree in Sumida-ku, Tokyo, and was built in conjunction with the opening of the Tokyo Skytree.

Located on the 5th and 6th floors of Tokyo Skytree Town, a shopping and dining complex, it is completely indoors and can be enjoyed on rainy days and in any season. It is also a great place to stop by when sightseeing at Skytree Tembo Deck, Tokyo Solamachi, or nearby Asakusa.

Things to Do

Let’s observe the daily lives of unique penguins

The “Penguins area,” where penguins live in an indoor pool with a water volume of about 350 tons, one of the largest in Japan, is known as the main attraction of the Sumida Aquarium. The “magellanic penguins” living in this area are characterized by the two black lines on their chests.

Their cute appearance as well as their gestures have attracted many fans and there is even a fan club for them. They are also known for having the most curious personalities among all penguins and may even entertain you with their comical movements at times.

The aquarium has a two-story atrium: on the fifth floor you can see the penguins swimming from the side as well as from below, and on the sixth floor you can watch them from above the tank. When you see the penguins up close, each one moves in a different way and is full of uniqueness and cuteness.

Each of the many penguins has a name, named after food and plants. You can identify the penguins by the color of the rings on their arms, so please try to find your favorite penguin.

The lighting in the Sumida Aquarium is bright during the day and dim at night, allowing creatures to live as naturally as possible. This also applies to the penguin area. During the daytime, you can see penguins swimming and moving energetically while at nighttime, you’ll have the opportunity to see them resting and sleeping.

The season of romance begins around February or March each year in preparation for the spring spawning. The sight of male and female creatures being together is such a cute and should not be missed. Baby penguins are also born every year. Be sure to pay attention to the penguins’ love story and their life as a couple.

Enjoy the marine world of the Ogasawara Islands, a World Heritage Site

Ogasawara Sea Life

“Ogasawara Sea Life” is the largest tank in the aquarium. Ogasawara Islands is located 1,000 km away from the center of Tokyo, even though the islands are part of Tokyo.

The sea of the Ogasawara Islands, a World Natural Heritage site, are deep, dark, and clear blue. It is also a treasure trove of rare fish and other creatures.

Ogasawara Sea Life has a two-floor atrium: on the fifth floor you can view the tanks from the same level as the fish, and from the sixth floor you can look down on the tanks.

Also, if you go around to the back of the Ogasawara Aquarium, you will find a section called “Aqua Scope,” which is lined with small round windows. Visitors can look into the tank as if they are diving beneath the sea.

Full of goldfish! Fantastic Japanese space


As the name suggests, “Edo-rium” is one of the largest goldfish exhibition areas in Japan, where visitors can see many beautiful goldfish swimming in a fantastic Japanese-style space with the theme of Edo. There are a variety of goldfish, from the kind you might see at a Japanese festival to the rarest.

The aquarium is designed to be viewed not only from the side but also from above. Enjoy observing the goldfishes with various angles.

An “extraordinary” space with countless jellyfish floating

Jellyfish Area

Among the many photogenic spots in the aquarium, the jellyfish area stands out the most. It has doubled in size since its renovation in 2020 and has been transformed into an even more extensive exhibit. The sight of beautiful jellyfish in various shapes and sizes floating in the water is mesmerizing. The gradually changing lighting creates a space where visitors can step into an “extraordinary” world.

The highlight of the jellyfish area is “Big Schale”, a 7-meter-diameter open-top, oval basin-shaped tank. It’s allowing visitors to enjoy the experience of taking a closer look at the fine details of the jellyfish’s body without the barrier of glass.

Another unique feature of the aquarium is that all 700 jellyfish of about 14 species were born at Sumida Aquarium. The aquarium has been raising jellyfish from babies for many years.

A close look at the mysterious creatures, the spotted garden eel

The Coral Reef area on the 6th floor is home to the spotted garden eel, with a total of approximately 300 individuals with three different species of eels.

The way they sway with the water flow, withdraw into the sand, and emerge again is interesting to watch.

Three different types of eels have distinct patterns and facial features, making it interesting to compare them and take the time to observe each one.

Feeding time

If you are lucky, you can even see their feeding time. When small plankton is placed in the tank, they stretch their bodies out and wait for the plankton to come near them.

Aqua Base to learn more about the aquarium

Aqua Lab
Aqua Base

In the “Aqua Base” area, visitors can take a close-up look at the backyard of the aquarium, which is usually closed to the public, and learn more about the animals in the aquarium and the work of the aquarium staff. This area consists of two parts: the “Lab” and the “Kitchen”.

In the “Lab” zone, visitors can observe the growth process of jellyfish from birth to adulthood. The aquariums are divided into tanks for each stage of growth, so visitors can actually see and compare the growth of the jellyfish. All jellyfish in the aquarium are bred in this laboratory. They are working to increase the number of jellyfish by carefully nurturing each one, which grow in different ways and eat different kinds of food depending on their species.

There is also a “kitchen” zone where visitors can closely observe the staff preparing food for the penguins and fur seals. They even adjust the amount of food based on the condition of the animals depending on the days.
