Direct answer
The current official release window is 2026 for PC and PlayStation 5. NEKCOM and Steam do not list an exact month or day, so any more precise date should be treated as unconfirmed.
What official sources confirm
Release window: 2026.
Current platforms: PC and PlayStation 5.
How to read the available evidence
The Steam store still says the game is not yet available and invites players to add it to their wishlist. Current first-party pages supersede the original 2022 announcement, which also named PS4; the active NEKCOM game page and Steam now list only PC and PS5.
The game has not launched. Trailers and developer interviews establish direction, but they do not guarantee final numbers, controls, optimal strategies, or content structure. This guide gives current NEKCOM and Steam pages priority; older announcements remain historical evidence and yield when newer first-party listings conflict.
How the sources were weighed
This page ranks evidence by how directly it supports the search question. Developer and official game pages establish the setting, platforms, and announcements. Steam establishes current PC store status and listed requirements. Community directories can show that a destination exists, but they do not replace a first-party statement.
NEKCOM — Showa American Story: First-party material used for the claim it directly names; pre-release details can still change.
Steam — Showa American Story: Current store record used for availability, platforms, and specifications; it is not proof of unannounced features.
Still pending
Exact date and time, regional timing, price, editions, preorder, preload, physical release, and launch-day patch details.
