What This Page Covers
This site has one subject and does not pretend otherwise. It covers Kaiyukan, the aquarium at Tempozan Harbour Village on Osaka Bay, through a single admission listing sold in three age tiers, with an adult ticket of about $18 and a rating of 4.8 across 14,894 reviews. Kaiyukan prices by demand, so the amount on the booking page moves with the date you pick. Schedule and closure details come from the operator's own pages, and where a fact depends on a date the site says so instead of freezing a number that will not hold.
Who These Pages Serve
A clear line runs through these pages. Kaiyukan itself owns the tanks, hires the keepers and decides opening hours, including the two-day January maintenance closure. This website is a separate thing: an independent guide that links out to the live booking page. Nothing is sold here, no order can be changed here, and no one behind these pages speaks for the aquarium. What they can do is gather the checkable facts about visiting so a reader arrives prepared rather than guessing.
Most visitors are not choosing between aquariums. The real decision is timing: which day, and at what crowd level. A listing page can make a ticket look flat and fixed when it is neither, so these pages show what an adult actually pays, about $18, how the three age tiers work, and how the amount shifts when demand rises. If you are planning around school holidays or a quiet weekday, that is the practical information, and it is what the guide pages are built around.
The aquarium is not open every single day, and this site does not pretend otherwise. Kaiyukan runs year-round except for a two-day maintenance closure each January, and that window is printed here rather than hidden. Because the closure dates shift from one year to the next, the pages point to the operator's calendar for the exact days rather than guessing. Those limits are stated, not smoothed over.
The editorial stance is worth spelling out. There is no invented reviewer claiming a day among the tanks, and no operator paid for a favourable mention. Ratings, review counts and prices come straight from the live listing or from Kaiyukan's own published material, so a reader can confirm any of it in a few clicks. Material that could not be verified was simply not written.
Where Each Number Comes From
Opening dates, the January closure window and the aquarium's own details here come from Osaka Aquarium Kaiyukan's published material, and the ticket figures come from the live listing itself. Where the operator publishes nothing, these pages say so instead of estimating.
| What This Site Covers | This site deals with one attraction: Kaiyukan at Tempozan Harbour Village on Osaka Bay in Japan. The year-round schedule with its two-day January maintenance closure, the demand-based pricing model and the admission details are all traced back to the operator or the live listing itself. |
|---|---|
| Admission Prices And Tiers | The admission structure comes from the live listing. One ticket is sold in three age tiers: an adult of 16 and over at about $18, a child aged 7 to 15 paying less, and a young child aged 3 to 6 least of all. The live booking page holds the exact figure for each tier on the date you choose, since Kaiyukan prices by demand and the amounts move with it. |
| Ticket Prices And Ratings | The listing publishes a rating of 4.8 from 14,894 reviews and an adult admission of about $18. Both are printed here as recent readings rather than permanent values, because demand-based pricing moves the amount with the date, and nothing on this site is frozen as a fixed rate. |
| Hours And Closure Days | Kaiyukan is open year-round, with one standing exception: a two-day maintenance closure each January. Because the operator shifts the exact dates from year to year, this site does not pin them to a fixed pair of days. The pages follow the operator's own calendar for the closure window, and a visit planned in January is worth checking against it before setting out for the bay. |
| Weather And Suspensions | The aquarium sits indoors at Tempozan Harbour Village, so Osaka weather, whether summer rain or a passing typhoon, does not stop a visit in the way it can disrupt an outdoor attraction. The one standing interruption is the January maintenance closure. When conditions or operations change, the operator posts updates on its official site, and that page is the place to check before setting out. |
| What Stays Unpublished | Opening dates, the January closure and the admission details come from the official Osaka Aquarium Kaiyukan source. When the operator publishes nothing, this site prints nothing rather than estimating. Where a figure is missing, the gap stays blank. |
How Facts Are Kept Honest
Three Promises, Held To
No aquarium ticket is sold directly on these pages. A booking for Kaiyukan is placed on the live listing, where the date is picked, payment is processed and the confirmation arrives. The current from-price, 4.8 rating and the review count behind it all sit there too.
Keeping the site running costs money, and outbound booking links are what pay for it. When a reader books a Kaiyukan admission through one of those links, the selling platform shares part of its own fee with this site at no extra cost to the buyer. The full picture, including what that arrangement does not influence, is laid out on the disclosure page.
The links are optional. The same Kaiyukan ticket can be bought on the live booking page reached any other way, or at the aquarium itself on Tempozan Harbour Village, at the same published price. Nothing on this site gates entry behind a click.
