Japan Stigmatized Property 3 Series vs JSP1 / JSP2

Scope of this comparison

This page is intentionally light. The wiki deep-dives Japan Stigmatized Property 3 only. Japan Stigmatized Property (JSP1) and Japan Stigmatized Property 2 exist so players understand what transfers—and what does not—when they buy the August 2026 third case file. You will not find full JSP1 anomaly encyclopedias here.

Shared DNA across the trilogy

All three games put you on association duty:

• Monitor CCTV on real-world Japanese stigmatized properties
• Work the midnight shift until 05:00
• Report anomalies; fail if you ignore stacks or spam false reports
• Toggle between standard and night-vision readings
• Choose a standard difficulty and a harder special-pay style mode

If you can survive one entry, you already understand ninety percent of JSP3’s grammar. How to Play still matters because fail thresholds and co-op additions deserve a fresh read.

JSP1 — origin solo case files

Japan Stigmatized Property introduced the desk fantasy and a set of properties that do not carry into JSP3. Memory of those layouts will mislead you. JSP1 also received a Nintendo Switch port, which is why storefront confusion happens—Switch shoppers sometimes assume every sequel follows. It has not for JSP3.

Tone-wise, many players remember JSP1 as the slower, quieter entry. That nostalgia is fine; it is not a difficulty chart for the third game.

JSP2 — new buildings, same solo spine

Japan Stigmatized Property 2 swapped in another quartet of locations and kept the solo surveillance spine. Press coverage emphasized fresh case files rather than a genre pivot. AI-assisted anomaly disclosures already appeared in series store text around this era—JSP3 continues that honesty on Steam.

If you 100%’d JSP2 yesterday, JSP3 will feel familiar within minutes. That familiarity fuels Mixed “reskin” reviews as much as it fuels comfort buys.

JSP3 — what actually changes

• New properties only: Sugiya Ryokan, Blue House, Kannonzaki Park, Y Residence. Study Properties; do not import JSP1 names.
• Online co-op (2P) with PC↔mobile cross-play and thermal camera access for pairs.
• 32 Steam achievements spanning regular, Hazard Pay, and co-op tracks—completion is co-op-gated.
• Platforms: Steam Windows/macOS + iOS + Android (see Platforms).
• Early reception: Mixed, with room-code and A/D complaints beside loop praise (Review).

Mechanically, A/D camera steps, W night vision, and hold-click reports remain the combat system. Series veterans should still skim Controls in case muscle memory fights a sticky build.

What does not transfer

• Property baselines and “that one window” memes
• Achievement progress
• Switch purchase ownership
• Any assumption that co-op exists in JSP1/JSP2 the way it does here

Bundles on Steam may sell JSP1–3 together. Bundles are pricing tools, not save migrations.

How to talk about the series without spoiling JSP3

Say: same job, new addresses, optional partner, Steam board expects co-op for 100%. Avoid saying “it’s just JSP1 again” if you have not sampled the new sites—clutter at the ryokan and park distance reads still create distinct fail stories.

Recommended path for trilogy players

1. Ignore old maps on purpose for one Normal clear per JSP3 property.
2. Decide if co-op is a feature or a chore for your friend group.
3. Only then chase Achievements with the Completion Route.
4. Keep expectations calibrated via the Review Hub instead of nostalgia arguments.

Editorial closer

The association’s fiction treats each release as another assignment packet. This wiki does the same: JSP1 and JSP2 are prior employment, not current SOPs. Clock into Japan Stigmatized Property 3 on its own cameras, and let the older buildings stay haunted without a full second wiki hanging off this domain.
