About This Kaiyukan Guide

This site covers one thing only: the Kaiyukan aquarium at Tempozan Harbour Village on Osaka Bay. It lays out what the attraction is, how admission pricing works, what entry involves, and when feeding sessions run. The facts are given plainly, for any reader who wants to check them.

The Basics

The subject is Kaiyukan, the aquarium at Tempozan Harbour Village in Osaka Bay, run by Osaka Aquarium Kaiyukan. This site is published without a named author, and no first-hand visit is reported anywhere in it. The pages explain admission, pricing and the feeding schedule, drawing on the operator's own publications. Nothing is sold here: any purchase happens on the live booking page.

Kaiyukan In Numbers

• The numbers here are small on purpose. One bookable listing exists, the Kaiyukan admission ticket, rated 4.8 from 14,894 reviews, and an adult pays about $18 to walk in.
• Kaiyukan runs demand-based pricing, so the amount charged moves with the date chosen. Treat any price shown here as a recent reading rather than a fixed rate.
• The aquarium sits at Tempozan Harbour Village on Osaka Bay, and the one listing on this site covers admission only, in a single category with a single published from-price.
• Feeding times come from the operator's own published schedule, with the operator's caveat that sessions may be cancelled or changed without notice depending on the animals' condition.
• The Kaiyukan admission ticket carries a 4.8 rating built from 14,894 reviews and an adult price of about $18. That amount is not fixed, because the aquarium prices admission by demand and the booking price moves with the calendar.
• This site currently offers one bookable product: an admission ticket to Kaiyukan, the aquarium at Tempozan Harbour Village on Osaka Bay. It is sold by the aquarium itself rather than a reseller, and the category is plain admission, with no guided add-ons bundled in.

Admission And Entry Details

• Entry splits by age. Anyone 16 or over pays about $18, a visitor aged 7 to 15 pays a reduced amount, and the youngest tier, ages 3 to 6, carries the lowest price of the three. Whatever the live booking page shows on a chosen day may sit above these figures.
• Entry works through a QR-code e-ticket, often paired with a chosen session. Buying ahead this way can mean skipping the purchase queue at the entrance on a busy day.
• The operator publishes opening hours, last admission and age-tier prices on its own site, and those figures appear across this guide. Where the operator publishes nothing, the pages here say so rather than estimating.
• Pricing at Kaiyukan is not flat. The operator prices by demand, so the amount attached to a date can shift across the calendar, and the listing reflects that movement rather than fixing a single rate. An adult of 16 or over starts around $18, with the exact figure for any given day shown on the live booking page.

Ticket Prices

• The about-$18 adult figure is a reading, not a promise. Because Kaiyukan sets prices by demand, the booking amount drifts with the calendar, so the number that matters is the one printed on the live booking page for the date a visitor actually has in mind.
• Third-party platforms sell dated Kaiyukan e-tickets at prices comparable to gate and dynamic rates, with 2026 visit dates already open for booking from early in the year.
• The listing prices in US dollars and the amount moves by date, so what is charged can differ from any figure printed here. Kaiyukan's own rates sit on a separate scale.
• Prices change by date, and Kaiyukan's demand-based system means two visitors picking different days can pay different amounts for the same admission. The from-price is the floor of that range, not the norm.
• What the listing sells is straightforward: general admission to Kaiyukan, nothing bundled on top. It carries a 4.8 rating built from 14,894 reviews, and it comes in three age tiers, with an adult of 16 or over at about $18. Demand-based pricing means the amount for a specific date may differ.

Feeding Times And Caveats

• Feeding sessions across the tanks follow the operator's own timetable, drawn from the aquarium's published schedule. The operator's caveat applies: times may be cancelled or changed without notice depending on the animals' condition.
• Kaiyukan closes for maintenance on set dates rather than a fixed weekly day off. The official calendar lists 13 and 14 January 2027 as closed, and where any dated closure and a general rule disagree, the dated calendar holds.
• Rather than guessing which days carry higher prices, this page points to the live booking page, which shows the tickets actually on sale for each date. Kaiyukan runs demand-based pricing, so the same admission costs different amounts on different days.
• No visit duration appears in anything the operator publishes for this ticket. Rather than invent a figure, this page states what the ticket covers and advises allowing a full afternoon, since the exhibits wind down through the building around the central tank.

When Kaiyukan Closes

• Typhoon season can affect opening hours in Osaka Bay. Any operational announcements sit on the operator's official pages, so this site points there instead of quoting closure rules it cannot confirm.
• The published closure window runs across 13 and 14 January 2027, with the aquarium reopening on 15 January 2027. Beyond that pair of maintenance days, Kaiyukan otherwise opens daily, while any additional closure dates rest with the operator, Osaka Aquarium Kaiyukan.
• This site covers one thing: tickets for Kaiyukan, the aquarium at Tempozan Harbour Village on Osaka Bay, in Japan, and how its demand-based ticket pricing works before you book.

One Ticket, One Tank, Every Floor

• This site links to a single ticket listing for Kaiyukan at Tempozan Harbour Village. The listing carries a 4.8 rating across 14,894 reviews, a strong showing for a single-venue attraction. One purchasable option sits inside that listing, covering general admission to the whole aquarium.
• A single purchase covers the whole building, every tank and every floor. The adult rate sits near $18 per person, though the booking price is tied to Kaiyukan's demand-based calendar, so the amount on the live booking page is the one that counts for a chosen day.
• One ticket covers the whole building: every floor of Kaiyukan, wound around the central Pacific Ocean tank, from the ring of small exhibits at the top down to the tunnel view near the bottom. What you pay depends on your age tier and the date, since Kaiyukan uses demand-based pricing rather than one flat rate.
• One point worth clearing up: the listing is not a flat, one-size ticket. It offers three age tiers, an adult of 16 or over at about $18, a child aged 7 to 15, and a young child aged 3 to 6 at the lowest of the three. Whichever tier applies, the same purchase opens every floor and every tank.
• The single option differs only by date, because the price itself moves with demand. Booking terms are whatever the live listing states at checkout.

Inside Kaiyukan

• Kaiyukan is built around one central tank representing the Pacific Ocean, with the visit route spiralling downward past habitats that ring it on every floor. The layout means you meet the same water from different depths as you descend, which is the idea the building was designed around.
• The aquarium sits inside Tempozan Harbour Village on Osaka Bay, beside the waterfront attractions and ferry terminals that share the district, which makes it a straightforward half-day outing. The operator, Osaka Aquarium Kaiyukan, runs the ticket sold through the listing on this site.
• Kaiyukan stands at Tempozan Harbour Village on Osaka Bay, Japan. The building is arranged around a central Pacific Ocean tank that the visit route circles on the way down.
• The aquarium is reached from Osakako station on the Chuo subway line, with the entrance a level walk from the stop at Tempozan Harbour Village. The same waterfront holds the giant Ferris wheel and the bay ferry pier, so the visit pairs easily with either before or after.
• Kaiyukan closes for maintenance on 13 and 14 January 2027, reopening on 15 January 2027. Checking the official calendar before choosing a date avoids planning an Osaka visit around a day when the doors stay shut.

Where The Numbers Come From

Every number on this page can be traced somewhere. The 4.8 rating, the 14,894 reviews and the roughly $18 adult admission all come from the live listing itself. Facts about the building, its home on Tempozan Harbour Village in Osaka Bay, and the way Kaiyukan prices by demand come from the operator's own published material. Where the aquarium has not published something, this page does not guess at it, and the gap stays open rather than being filled with a convenient estimate.

What This Page Leaves Out

• No per-date booking price appears on this site, because the figure moves with Kaiyukan's demand-based calendar. What the ticket covers is stated instead, and the live booking page holds the current price for the date you pick.
• Some numbers around this aquarium have never been settled by the sources used here. None states how long a typical visit runs, none publishes a count of the animals held across the tanks, and the exact water volume of the central tank appears only in figures the operator has not confirmed, so none of the three appears anywhere on this site.
• No visitor total appears here. The 14,894 reviews attached to the listing span its entire published life, so the count describes the listing itself rather than any single year of visits, and it stays labelled that way rather than dressed up as an attendance figure.
• Per-date ticket prices are left out on purpose. Kaiyukan sells admission through a demand-based calendar, so the amount changes with the day you pick and no single figure holds still. The ticket is described by what it covers, and the live booking page carries the actual price for the date you choose.

How This Guide Earns

Booking links on this site carry referral tags. When you buy the Kaiyukan ticket through one of them, the seller pays this site a share of its own fee, and the amount you pay stays the same. Nothing is sold directly here. The links lead to the same live listings you could find on your own, and the price at checkout is the seller's price either way.

What These Pages Hold

• The homepage is where the booking happens on this site. One product sits at its center: the Kaiyukan admission ticket, rated 4.8 from 14,894 reviews, sold at an adult price of about $18 under a demand-based calendar that moves the figure by date. Around it you will find the practicalities of getting to Tempozan Harbour Village on Osaka Bay.
• Each guide sticks to one subject at a time: how the dynamic pricing calendar works, what the two-day January maintenance closure means for winter trips, how to reach Tempozan Harbour Village by rail or ferry, and what separates a booked ticket from a walk-up one.
• The answers take the short questions one by one, from what a Kaiyukan ticket costs and why the price shifts by date, to where the aquarium sits on the Osaka Bay waterfront and what to expect from a full circuit of the tanks.
• The FAQ handles the transactional questions: which of the three age tiers applies to your group, why an adult pays about $18 while children aged 7 to 15 and young children aged 3 to 6 pay less, and how demand-based pricing shifts the amount depending on the date you pick.
