Miyajima Public Aquarium

The aquarium's own English page gives the operating details: daily opening at 9:00, closing at 17:00, last admission at 16:00, and free entry for children under 4.

This page on the Hiroshima Travel Guide covers what the aquarium holds, how the journey from Hiroshima works, and how the visit pairs with the shrine, the tides and the rest of the island.

What Is The Miyajima Public Aquarium On Miyajima?

The Miyajima Public Aquarium, located at 10-3 Miyajima-cho, Hatsukaichi-shi, in Hiroshima Prefecture, is dedicated to the marine life of the Seto Inland Sea, including finless porpoises, and is open daily from 9:00 to 17:00 with last admission at 16:00. Children under 4 years old enter free. The aquarium's English page is the source for all of these figures.

The institution's identity is regional rather than spectacular. Instead of importing ocean giants, its exhibit list reads as a tour of local waters: Mudflats of Miyajima, Sea of Healing, Whales of Setouchi, Mysteries of the Sea, Blessings of the Sea, Rocky Shore of Friendship, and From Mountains to Sea, alongside penguin pools, sea lion pools, otter pools and seal pools. The English page also lists a Live Show Pool used for sea lion performances and feeding sessions.

A reasonable framing for the visit: the aquarium is a weather-proof, tide-proof counterweight to the island's headline sights. Itsukushima Shrine depends on the tide and the daylight, the Mount Misen ropeway depends on the weather, and neither cares much about a rainy afternoon. The aquarium runs the same hours regardless.

Where Is The Miyajima Aquarium And How Do You Get There From Hiroshima?

From JR Hiroshima Station, the JR Sanyo Line takes about 25 minutes to Miyajimaguchi, the ferry then crosses to Miyajima Pier in about 10 minutes, and the aquarium is about 25 minutes on foot from the pier or about 10 minutes by shared taxi or taxi, per the aquarium's own access page. The full address is 10-3 Miyajima-cho, Hatsukaichi-shi, Hiroshima 739-0534.

That access chain is worth breaking into its parts, because each leg has a separate fare and a separate operator. The train is JR West, the ferry is a separate operator (JR West Miyajima Ferry or Miyajima Matsudai Kisen, both crossing in about 10 minutes), and the island leg is on foot or by taxi. The visitor tax of 100 yen is charged separately when entering the island, with preschool children exempt, and the crossing details are covered in full on the Hiroshima to Miyajima transport guide.

The Hiroden streetcar is the alternative rail route: Hiroden Line 2 runs to Miyajimaguchi at a flat fare of 240 yen for adults and 120 yen for children on all lines including the Miyajima line, a fare in force since 1 February 2025, and IC cards such as ICOCA and Suica are accepted on board. The streetcar is slower than the JR train but departs from stops in the city centre, so the right choice depends on where in Hiroshima the day starts. The wider comparison, including the answer to which is better to visit, Hiroshima or Miyajima, is a planning question rather than a transport one.

What Are The Miyajima Aquarium Opening Hours And Ticket Prices?

The Miyajima Public Aquarium is open daily from 9:00 to 17:00, with last admission one hour before closing at 16:00, and children under 4 years old enter free, according to the aquarium's English page. The aquarium is located at 10-3 Miyajima-cho, Hatsukaichi-shi. It will be closed for facility repairs from 1 December 2026 to 31 March 2027.

Beyond the under-4 rule, entry tickets for the aquarium can be booked through the site's featured product, listed alongside the wider selection on the Miyajima tour overview page.

The hours matter for sequencing more than for budgeting. Last admission comes at 16:00, so an afternoon aquarium slot has a hard edge to it in a way the shrine does not, and the ferry timetable (last JR departure from Miyajima 22:14) does not rescue a late aquarium arrival.

What Can You See Inside The Miyajima Aquarium?

The exhibit list on the aquarium's English page names Mudflats of Miyajima, Sea of Healing, Whales of Setouchi, Mysteries of the Sea, Blessings of the Sea, Rocky Shore of Friendship and From Mountains to Sea, plus penguin pools, sea lion pools, otter pools and seal pools, and a Live Show Pool for sea lion performances and feeding sessions. The collection centres on Seto Inland Sea creatures, including finless porpoises.

The show pool is the only scheduled-entertainment element. The English page describes it as the venue for sea lion performances and feeding sessions, which makes it the natural anchor for a visit with children: the animal pools can be walked in any order, but a feeding session has a start time. Session times are not listed on the English page, so checking the day's schedule at the entrance desk is the practical move.

For visitors building the whole island into one circuit, the aquarium's mudflat exhibit pairs naturally with the real thing: at a tide level of about 100 cm or lower the seabed in front of the torii is exposed and the gate can be walked to, while at about 250 cm or higher the shrine and torii appear to float. Those thresholds, and how to read them on the day, are laid out in the site's guide to when low tide falls at Miyajima.

Can You Visit The Aquarium And Itsukushima Shrine On The Same Day?

Yes, and the two fit comfortably in one day: Itsukushima Shrine opens at 6:30 in the morning and closes between 17:00 and 18:30 depending on the season, while the aquarium runs 9:00 to 17:00 with last admission at 16:00, so a morning shrine visit followed by an early-afternoon aquarium slot leaves slack in the timetable. The shrine is a 10 to 15 minute walk from the ferry pier along Omotesando.

A shrine-first order has two arguments behind it. The shrine opens at 6:30, hours before the aquarium's 9:00 start, so early arrivals burn the morning at the shrine and the walk to the aquarium fills the middle of the day. And the tide, not the clock, governs the best shrine moments: the floating appearance needs a high tide, the walk to the torii a low one, and the tide cycles roughly twice a day, so either state can fall in the morning or the afternoon alike.

The reverse order, aquarium first, suits a visitor arriving on a morning high tide who wants the floating torii view in late afternoon light, since the shrine stays open an hour later than the aquarium in the March-to-October season.

For visitors compressing Hiroshima city and the island into a single day, the sequencing problem gets harder, and the timed version on the Hiroshima and Miyajima in one day itinerary treats it in detail.

Is The Miyajima Aquarium Good For Families With Kids?

For families the aquarium's strongest practical points are free entry for children under 4, a single indoor circuit of penguin, sea lion, otter and seal pools plus a live show pool for feeding sessions, and hours of 9:00 to 17:00 with last admission at 16:00, though the facility is closed for repairs from 1 December 2026 to 31 March 2027.

The indoor point matters on Miyajima more than on a city sightseeing day. The island's core experiences are outdoors: the shrine corridors, the Omotesando lane, the ropeway up Mount Misen. Rain shrinks that list fast, and the aquarium is the island's one substantial indoor venue. Families planning around the weather may also want the wider picture in the site's guide to what to wear on Miyajima island.

A family day on the island also runs into the visitor tax at the ferry: 100 yen per person on entry, preschool children exempt, charged with the ferry fare. The arithmetic of a family trip, including that tax, is laid out in the site's answer to how much the Miyajima visitor tax is.

What Else Is There To Do Near The Miyajima Aquarium?

Near the aquarium, the main options are Itsukushima Shrine and the Mount Misen ropeway, whose cars run 9:00 to 16:00 with last descent at 16:30 and an adult return fare of 2,000 yen. The island's walking geography is linear, so a full day strings the shrine, the aquarium and the ropeway together. Staying overnight adds the illuminated torii, lit from 30 minutes after sunset until 23:00 and viewable free from shore.

The walking geography is linear. A full-island day strings the shrine, the aquarium and the ropeway together, and the Miyajima day trip guide maps the whole sequence.

For visitors with two days rather than one, the calculus changes completely: an overnight stay on the island unlocks the illuminated torii after dark, reported as lit from 30 minutes after sunset until 23:00 and viewable free from shore, and the last JR ferry back (22:14 from Miyajima) stops being a constraint. The Miyajima overnight itinerary covers that version, including the ferry timings and the ryokan check-in customs.

Two site pages answer the island's peripheral questions directly: whether the Miyajima torii gate is lit up at night, and whether you can swim at Miyajima, a question the aquarium's marine exhibits answer only by contrast: the sea life is watched there, not joined.

When Is The Best Time Of Year To Visit The Miyajima Aquarium?

The Japan Meteorological Agency (JMA) 1991-2020 station normals for Hiroshima show the driest months are January at 46.2 mm of rain and December at 54.0 mm, the wettest is July at 279.8 mm, and August has the highest average daily high at 32.8 °C with January the lowest average daily low at 2.0 °C, so an indoor aquarium visit is least affected by the seasons of any stop on Miyajima. No single month is named here as best; the figures are averages.

The seasonal table, with the monthly rainfall totals and temperature averages from the JMA normals:

Winter visitors get the shortest end of the daylight, with the shrine closing at 17:00 in December, and the aquarium is due to close for facility repairs from 1 December 2026 to 31 March 2027. The fuller winter picture, including what stays open across the city, is on the site's Hiroshima in winter guide.

Should You Buy Miyajima Aquarium Tickets Before You Travel?

Yes, mainly for convenience rather than price. A pre-booked ticket skips the desk at the entrance, and advance purchase commits the day's plan around the 9:00 to 17:00 hours, with last admission at 16:00, an anchor many one-day itineraries want. A ticket bought that morning on the island still works, so buying ahead is optional. Children under 4 enter free, and the aquarium closes for repairs from 1 Dec 2026 to 31 Mar 2027.

The decision matters less on price than on timetable. The last-admission rule at 16:00 means a ticket bought that morning on the island still works, but a ticket held in advance commits the day's plan around it, which on a one-day Miyajima itinerary is exactly the anchor many visitors want. The site's featured product for the aquarium sits alongside the wider selection on the Miyajima tour page.

For travellers assembling more than one island component, two companion products appear in the site's roster: a bike-and-boat combination covering Hiroshima and Miyajima in a single guided loop, and a private custom option with a local guide whose duration flexes to suit the plan. Both are shown in the band below with live prices and ratings.

How Does The Aquarium Fit Into A Longer Hiroshima Itinerary?

On a two or three day Hiroshima plan, Miyajima usually takes a full day, and the aquarium slots into it as either a half-day anchor or a weather fallback, with the Peace Memorial Park, Hiroshima Castle grounds and Shukkeien Garden filling the city days; the site's two and three day itineraries sequence all of these with timed transport. The aquarium's fixed 9:00 to 17:00 hours make it the easiest island component to schedule around.

The city-side anchors carry their own admission details: the Peace Memorial Museum charges 200 yen for adults and is free for junior high students and younger, Hiroshima Castle's keep has been closed to visitors since 22 March 2026 with the grounds and exterior open, and Shukkeien Garden charges 350 yen for adults with school students free. Those entries, not the aquarium, are the core of the city days; the Hiroshima in 2 days itinerary and Hiroshima in 3 days itinerary arrange them.

A simple split that follows from these hours: morning at the shrine on the tide, early afternoon at the aquarium, and the late afternoon on Omotesando or the Misen trails.

Common Questions About The Miyajima Public Aquarium

Held to that role, morning shrine, early aquarium afternoon, Omotesando at dusk, it earns its place on almost any Miyajima day the weather or the travelling party throws at it.
