Aquarium (Japan)

Aquarium (Japan) on arcade

Compiled by Alfred J. Hall · Editorial standards · Published July 2, 2026

Aquarium (Japan) is a simulation game that originally hit the PlayStation in December 1998, published by Electronic Arts Square exclusively for the Japanese market. It later saw a European Windows port in 2000 under the simple title Aquarium. This version you can play in your browser is a ROM of that original release, so you are getting the same tranquil fish-tank management experience that charmed a small but dedicated audience back in the late 90s. It is not an arcade game in the traditional sense - no high scores or quarter-munching action - but rather a peaceful, slow-paced sim that fits nicely into a retro gaming library for those who want to relax rather than react.

How to Play Aquarium (Japan) Online

Getting Started

When you launch Aquarium, you will be greeted by Japanese menus - there is no English option. The main menu has options like starting a new aquarium, loading a saved one, and settings. Use the arrow keys to navigate and the X button to confirm selections. If you are unfamiliar with Japanese characters, try selecting the topmost option to begin a new game.

The core loop is simple: you are given an empty tank where you can add various types of fish, decorative plants, and tank ornaments. Money is earned over time as your fish thrive, which you can then spend on new species or upgrades. You must keep an eye on water temperature, cleanliness, and feeding schedules to keep your aquatic friends healthy. The game runs in real time, but you can speed up or pause using the options in the menu.

Since this is a simulation with no real arcade urgency, take your time exploring the interface. The controls are straightforward once you know which button does what. If you get stuck, remember that the B button (S on keyboard) often cancels or goes back. Enjoy the calm atmosphere - this is a game about patience and creativity, not quick reflexes.
