Shinjuku Anomaly

Shinjuku Anomaly is a short horror visual novel by AMATA Games. You take on a night job in Shinjuku and are tasked with photographing unusual phenomena there. The game combines a gloomy, hand-drawn-looking presentation with a clearly defined observation task and multiple endings.

Shinjuku Anomaly releases on Sep 30, 2026 at 10:00 a.m. JST for PC via Steam. AMATA Games confirmed the date on Sep 28 in its own release announcement. The previously stated date of Sep 29 was based on an earlier store listing and is therefore outdated.

At launch, PC (Windows) via Steam is confirmed. Further native platform versions are currently not announced.

The core of the game follows four rules: discover anomalies, photograph them, get close enough for a clear image but not too close, and return to the agency once the film is used up. The short horror visual novel is designed for single players and offers multiple endings.

The Steam version requires a 64-bit system with Windows 11 and at least 8 GB RAM. AMATA currently does not list any further recommended hardware values.

AMATA Games transparently states on the Steam page that some of the background graphics were created with generative AI. Otherwise, the character and scene presentation is designed as a stylized 2D horror visual novel.

The theme song of Shinjuku Anomaly is called „Hyakkiyakou“ and comes from the Japanese loud girls group YAMIKUMO. The track plays in the ending and in the official trailer. AMATA also released a collaborative lyric video for the announcement of the release date, in which the group's members are woven into the game world as anomalies.
