About 日本事故物件監視協会3 -Japan Stigmatized Property-
Japan Stigmatized Property 3 puts you in the role of an observer for the Japan Stigmatized Property Association. You watch live feeds from real‑world Japanese locations between midnight and five a.m., looking for randomly occurring anomalies.
The game offers selectable difficulty, night‑vision and standard camera modes, and permits unrestricted streaming and monetisation. It runs on Windows and macOS, supports Steam achievements, custom volume, adjustable difficulty, mouse‑only input, Steam Cloud and family sharing.
01 / THE GUIDE
Surveillance Gameplay
During each shift you monitor camera feeds from four assigned properties. Anomalies appear at random and may be visible only through the standard view or the night‑vision mode, so constant visual attention is required.
When you notice an anomaly you must report it immediately. Repeated false reports cause a mission failure, while uninterrupted monitoring from 00:00 to 05:00 without error results in mission success.
- Keep the feed centered to reduce the chance of missing brief visual glitches.
- Log the exact time an anomaly appears; the timestamp can help verify its authenticity.
02 / THE GUIDE
Anomaly Types
The game lists several possible irregularities: furniture moving on its own, objects appearing or disappearing, human or spiritual intruders, lighting malfunctions, floating orbs, bloodstains on walls, and video‑feed noise or interference.
These events are described as “something beyond imagination,” indicating they can be visually unsettling and may require a specific camera mode to be seen.
- Watch for subtle lighting shifts; they often precede larger visual events.
- Compare current footage with earlier moments to spot objects that have vanished.

Shift Structure
Each assignment consists of four properties monitored during a midnight shift that runs from 00:00 to 05:00. The shift length defines the window in which you must stay vigilant and report any anomalies.
Completing the full five‑hour window without a false report counts as a mission success, while any missed or incorrect report ends the mission early as a failure.
- Take brief pauses only during natural lulls in camera activity to stay fresh.
- Maintain a quick note‑taking routine to log each anomaly as it occurs.
04 / THE GUIDE
Difficulty Settings
Before starting a shift you can choose between Normal and Hazard Pay (Hard) difficulty. The selected level influences how frequently and how subtly anomalies appear, demanding sharper observation on the harder setting.
Both difficulties keep the same core objectives, but Hazard Pay raises the risk of mission failure through more frequent or less obvious events.
- Begin on Normal to learn typical anomaly patterns before attempting Hazard Pay.
- Use the custom volume controls to hear faint audio cues that may hint at hidden events.

Streaming & Monetization
The game explicitly permits streaming and broadcasting while you conduct surveillance duties. No restrictions are placed on monetisation methods such as Super Chats, and permission requests are not required for individuals or corporations.
This openness allows creators to share live gameplay, discuss anomalies in real time, and potentially earn revenue without additional in‑game constraints.
- Explain why you consider an event an anomaly before reporting it to keep viewers engaged.
- Adjust the custom volume controls to balance game audio with your commentary.
