Sumida Aquarium Tokyo Guide: Tickets, Hours, Exhibits and Skytree Tips

Is Sumida Aquarium Tokyo Worth Visiting?

Sumida Aquarium is a compact, design-led aquarium rather than a full-day marine park. Plan on 1.5 to 2 hours inside. It suits families already at Skytree, design fans and anyone who wants a dry indoor stop. It is entirely indoors, so rain and summer heat do not matter.

The aquarium holds roughly 7,000 animals across the 5th and 6th floors. Some sources count more than 10,000 sea creatures, so treat any single total as approximate. Expect a boutique layout with short sight lines, not a giant open hall.

Adult admission is ¥2,700 as a baseline. That is pricier than many Tokyo aquariums, and Tokyo Sea Life Park in Edogawa is larger. You pay here for the setting, the penguin pool and the easy location. If your priority is very large tanks and whale sharks, Osaka is the better aquarium trip.

Most visitors pick this aquarium as one stop inside a wider Skytree area day. Our Tokyo attractions guide shows how it fits with other districts.

• Best for: families, design lovers, rainy-day plans
• Time needed: 1.5 to 2 hours
• Adult entry: ¥2,700 baseline, subject to seasonal change
• Location: 5th and 6th floors of Tokyo Solamachi

Sumida Aquarium Tickets, Hours and Prices

Adult admission is listed at ¥2,700, and the baseline can change seasonally. Check the official aquarium site for current fares and child pricing before you go. Special summer events have had their own discount tickets, so prices are not always flat.

Buy online if you can. The official site recommends online tickets so you skip the line at the 5th-floor ticket area. That line is the main avoidable delay on busy days.

Hours differ by day type. Weekdays run 10:00 to 20:00. Weekends and public holidays run 9:00 to 21:00. Japan-guide lists no regular closing days. Last admission comes before closing, so confirm the cutoff on the day's schedule.

How to Get to Sumida Aquarium from Asakusa and Oshiage

The aquarium entrance is on the 5th floor of Tokyo Skytree Town. This complex spans the area between Tokyo Skytree Station on the Tobu Isesaki Line and Oshiage Station. Oshiage is served by the Asakusa Subway Line, the Hanzomon Subway Line and the Keisei Oshiage Line.

From Asakusa, you can walk about 20 minutes across the Sumida River. That route is the scenic option and works well in dry weather. Take the subway instead if it is raining or hot.

Buses also reach Skytree directly. From Ueno Station the bus takes 30 minutes and costs ¥230. From Haneda Airport it takes 50 to 70 minutes and costs ¥1,200. Services run every 1 to 3 hours from Haneda, so check the timetable.

• Asakusa: about 20 minutes on foot across the Sumida River
• Oshiage Station: Asakusa, Hanzomon and Keisei Oshiage lines
• Tokyo Skytree Station: Tobu Isesaki Line
• Ueno bus: 30 minutes, ¥230
• Haneda Airport bus: 50 to 70 minutes, ¥1,200

Must-See Exhibits at Sumida Aquarium

Start with the penguin pool. Magellanic penguins live in an indoor open pool holding about 350 tons of water. Japan-guide calls it the largest open indoor tank in Japan. Fur seals share the space, and thick clear glass gives views from many angles.

Next, look for the jellyfish area. Around 700 jellyfish of 14 species are on display. Moon jellies drift in the Big Schale, a round tank with about 500 of them. A 5th-floor jellyfish lab shows how the animals are bred and raised.

The garden eel tank links to Skytree by number. It opened with 634 spotted garden eels, matching the tower's 634 meters. Eel numbers may differ today, so treat that as the opening story.

The Ogasawara Sea tank is 6 meters deep. It recreates the waters around the Ogasawara Islands, a World Natural Heritage site. The official site lists 450 fish of 45 species in that large tank.

Finish in the Edorium. It is an Edo-themed goldfish exhibit with about 20 varieties on display.

Other small features add variety. A Mangekyo tunnel uses 5,000 mirrors. The Ogasawara Base area shows green sea turtles, including two babies named Hoshi and Sora in 2026.

All tanks use artificial seawater. Wikipedia notes this avoids hauling natural seawater inland. It is why an ocean aquarium can operate this far from the coast.

Penguin Relationship Chart and Daily Feeding Times

Sumida publishes a Penguins Relationship Chart each year. It maps the social ties among the penguins, like a soap opera cast list. The official site lists a 2026 edition. Look for it near the penguin pool and use it to pick out individual birds.

The penguin group also has new members. Chicks Jinbei, Kibi and Dango were born in spring 2026. Four rookie penguins were on public display. Rosters change, so expect the chart and the birds to differ from older photos.

Feeding times drive a good visit. The schedule below is from the official program list. Times can shift by day type, so confirm the same-day program on arrival.

How to Combine the Aquarium with Skytree

Use the aquarium as your midday indoor block. Visit Skytree in the morning or near sunset, then slot the aquarium between those two ascents. This avoids standing outdoors in the hottest hours or in rain.

A workable plan for a weekday follows. Arrive around 10:00 with an online ticket. Catch the 10:30 penguin meal, then work through the 5th and 6th floors. Finish by noon and eat in Solamachi.

For a later plan, arrive around 15:00. Watch the 16:00 penguin feeding and the 16:30 fur seals. Evening hours also suit couples, because the aquarium runs a night-themed atmosphere. Check the official program for lighting details.

Summer visitors had an extra option. The Sumisui Fireworks projection-mapping event ran July 14 to September 14, 2026. It has ended for this year. Our Best Time To Visit Tokyo Month By Month 2026 page covers seasonal events.

If you want another dry, indoor stop on a different day, try the Miraikan science museum. The Miraikan official site lists current exhibits and hours.

Mistakes to Avoid and Accessibility Tips

Avoid weekend afternoons. Corridors are narrow, and tank-side spots fill quickly. Weekday mornings or the last two hours before closing are calmer.

Do not skip the online ticket. Queueing at the 5th-floor entrance wastes time you want for the 10:30 or 13:30 penguin meal. Buy before you arrive and keep the QR code ready.

Do not miss Ogasawara Base. Many visitors rush to the penguins and skip the sea turtle area. The 10:30, 13:30 and 16:30 feeding times make it easy to catch.

With toddlers, use the 5th-floor stroller parking. The multi-level layout is easier without a stroller. Check the official site for lift and wheelchair details before you go.

Finally, do not get lost in Solamachi. The aquarium entrance is on the 5th floor of the mall. Follow floor signs, not just Skytree signs.

Where to Eat and Stay Near Sumida Aquarium

Eat inside the aquarium or in the mall. The Penguin Café serves original themed menus, and alcohol is available. Solamachi has more than 30 restaurants, which suits groups with different tastes.

For a base nearby, Asakusa is a short walk across the Sumida River. Ryogoku, the sumo district, is another option. Evening walks along the river are an easy way to end the day.

Compare neighborhoods in our Tokyo hotel guide before booking. Haneda Airport access takes 50 to 70 minutes by bus, which helps arrival and departure days.
