# Osaka Aquarium Kaiyukan Tickets

> An independent guide to Kaiyukan, the aquarium at Tempozan Harbour Village on Osaka Bay, covering tickets, dynamic pricing, opening patterns and how to book.
> Kaiyukan sits in Tempozan Harbour Village on the Osaka Bay waterfront, and this guide covers the one admission ticket listed, how its demand-based pricing moves by date, and what the live booking page shows before you commit.
> It explains the ticket, the date-based pricing calendar and the visit basics, and links a single admission listing. The site itself sells nothing.
> The ticket link on this site is a paid referral link, and the price you pay stays the same whether you arrive here or go direct.


## Key facts

- Kaiyukan uses demand-based pricing, so the ticket price shifts with the date you pick, and the booking price follows the aquarium's own calendar rather than a flat rate.
- The single admission ticket is run by Osaka Aquarium Kaiyukan itself, with prices starting from $4.75 and moving by date under the aquarium's demand-based pricing.
- Because prices move with demand, the cheapest dates tend to sit outside Japanese holiday periods and weekends, so a weekday visit in a quiet season usually reads lower on the calendar.
- The aquarium sits at Tempozan Harbour Village in Osaka Bay, next to the giant Ferris wheel and the shopping mall, which makes it easy to fold into a wider waterfront afternoon.
- The live listing carries a 4.8 rating across 14,894 reviews, published by the aquarium's own operator, and the from-price reads $4.75 with the final figure set by your chosen date.
- One admission category exists, one operator runs it, and one published from-price covers it, so the choice here is less about ticket tiers and more about picking the right date.
- The live booking page holds a 4.8 rating across 14,894 reviews, with the from-price reading $4.75 and the final cost moving with the date-specific demand calendar.
