1999TOKOYO Building

1999TOKOYO Building is a psychological horror adventure and visual novel from the developer team TOKOYO FUDOSAN. It centers on Akira, who lives in a decaying indoor amusement park and looks into the secrets of his housemates. The game combines exploring spatial environments with dialogue choices.

Kodansha has announced Nov 10, 2026 as the planned release date for the PC version. The free demo with the first chapter was released on Oct 14, 2026. The full version has not been released as of today.

So far, the game has only been announced for Windows PC via Steam. No native versions for PlayStation, Xbox, Nintendo systems or mobile devices have been confirmed.

The adventure switches between two play styles: in the exploration sections, three-dimensional rooms are examined from a 360-degree perspective using point and click. Information you collect then helps you judge the residents more accurately.

In the visual novel sections, response options shape how encounters unfold. Some individual decisions can end the story immediately. Characters react with animated facial expressions during conversations.

Steam lists Windows 10, an Intel Core i3, integrated Intel HD 4000 graphics and 2 GB of free storage as minimum requirements. Recommended are an Intel Core i7, a GeForce GTX 1060 and 4 GB of storage. These figures apply to the PC version.

The story takes place in December 1999 in a run-down indoor amusement park surrounded by huge water basins. Although hardly any visitors come anymore, several people still work and live there. Akira enters the building with no memory of his past and is taken on as an employee by the operator.

Rumors about missing people surround the place. The various rooms and the daily life of its residents form the backdrop to Akira's search for answers.

Akira gets to know his housemates not only through conversations. Clues from the environment open up further ways to interpret their statements and reactions. The choice of words has consequences: upset a character or reveal too much about them, and you can fail.

This mix of investigation and dialogue choices forms the core of the story. The publisher describes the characters as headstrong and their personal stories as an important part of the game.

The people in the TOKOYO Building include the fortune teller Camellia, the aquarium keeper Samejima, a performer in a vampire costume and Tokoyoman, the hero of the local stage show. The operator Kazuto Yano and the employee Hajime Kotobuki handle the daily running of the amusement park. Their different personalities shape Akira's social choices.

Kodansha lists Japanese, English and Simplified Chinese as supported languages. The game is announced as a single-player adventure. A German localization has not been confirmed so far.

The music is composed by Yasuhiro Nakashima. According to the publisher, the musical accompaniment adapts to Akira's emotions as his story progresses. The locations have angular 3D visuals, while the characters in conversations are animated 2D figures.

Development is handled by the three-person Japanese team TOKOYO FUDOSAN (常夜不動産). Its members cover scenario writing, illustration with Live2D, and game design or programming. Kodansha is publishing the game as part of its Game Creators’ Lab. According to the company, this is the team's debut project.
