Hayaoshi Quiz - Ouza Ketteisen (Japan)

What is Hayaoshi Quiz - Ouza Ketteisen (Japan)?

Compiled by the Retro Games Online Editorial Team · Updated June 23, 2026

Hayaoshi Quiz - Ouza Ketteisen is a Japanese-exclusive quiz game for the original Game Boy, released sometime in the early 1990s. I've seen it pop up on a few import lists over the years, but concrete details about the publisher or developer are not widely documented - likely a small studio or a publisher that focused on quiz software for the Japanese market. The title roughly translates to "Fast Quiz: Throne Deciding Battle," which sets the stage for a rapid-fire trivia competition.

The player goes head-to-head against AI opponents in a series of quiz rounds. Questions appear on screen, and you must choose the correct answer from multiple choices as quickly as possible. Speed seems to matter as much as accuracy - the faster you answer, the better your score. Based on the genre conventions of the era, you probably advance through a bracket-style tournament, knocking out rivals to claim the "throne." The game uses the standard D-pad for selection and the A button to confirm your answer.

Today, Hayaoshi Quiz - Ouza Ketteisen is a niche curiosity for collectors of Japanese Game Boy software. It doesn't have any standout graphics or audio hooks - it's a straightforward quiz game, and the menus are entirely in Japanese, which can be a barrier. But if you enjoy retro quiz titles and want to experience a fast-paced trivia game with a competitive twist, this one is worth a quick look. It's not a must-play, but it fills a specific corner of the Game Boy library with charm.

How to Play Hayaoshi Quiz - Ouza Ketteisen (Japan) Online

Getting started is straightforward but expects you to navigate Japanese menus. When the game boots, you'll likely see a title screen with options like "1P Game" or "Start." Use the D-pad to highlight the first option and press X (A button) to confirm. The core loop is answering quiz questions - each round presents a question in Japanese text, and four answer choices appear. Quickly press the D-pad to move the cursor over your pick and confirm with X.

If you don't read Japanese, you can still enjoy the game by trial and error, but it helps to have a basic grasp of hiragana and katakana. The game scores based on speed, so don't hesitate too long. There are likely multiple rounds, and losing a round might end your run - so aim for perfect answers. Press Enter to start the game from the title screen, and V to access any configuration menus if present.
