Direct answer

The story follows Chigusa Choko, a young stuntwoman who is killed after arriving in Neo Yokohama, mysteriously returns from the dead, and crosses a post-apocalyptic United States to find her missing sister, uncover the truth, and seek revenge. Older official copy spells her name Chouko and calls the city New Yokohama.

What official sources confirm

The journey is framed around truth, revenge, and finding Choko's missing sister.

The setting blends Japanese and American retro culture after a mysterious catastrophe.

How to read the available evidence

Before the catastrophe, Japan's economic power and migration reshaped the United States into a place where Japanese and American culture visibly merged. The disaster destroyed social order and left zombies, monsters, survivors, criminal groups, and an organization attempting to rebuild. The official material deliberately leaves the cause of the catastrophe, the reason for Choko's revival, and her sister's fate unresolved.

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.

Steam — Showa American Story: Current store record used for availability, platforms, and specifications; it is not proof of unannounced features.

NEKCOM — A Brand New RPG: First-party material used for the claim it directly names; pre-release details can still change.

Gematsu — 4Divinity Gamescom 2026 overview: A dated report used for what its writer saw or recorded; preview-build observations are not final specifications.

Still pending

The catastrophe's cause, Choko's resurrection, her sister's fate, the ending, and how the older and current spellings appear in the finished localizations.

Pending details are not filled with guesses. They will be updated only when a traceable official source appears.

Both names have appeared in official material; this guide uses the newer Neo Yokohama for current references.

SettingWhat Does Showa 66 Mean?

Showa 66 is the game's fictional era. A developer interview describes it as a parallel 1991 where Japan's Showa era did not end in 1989; in this timeline, Japan used its economic power to buy much of the United States and Japanese culture became deeply rooted across America.
