Onion Game has confirmed a special physical edition of Stray Children for Nintendo Switch, with the "Treasure Box" scheduled to release in Japan on December 10, 2026.
The announcement outlines a boxed set aimed at collectors that supplements the standard physical cartridge with a variety of tangible extras.
The Treasure Box contents have been listed by the publisher: along with a standard physical copy of Stray Children for Nintendo Switch, the package includes an art book, a CD containing music from the game, a cloth map, and an acrylic keychain.
The company also noted that, while the Treasure Box has only been officially announced for the Japanese market, the physical cartridge will display English text when the Nintendo Switch system language is set to English.
In journalistic terms, Onion Game summarizes Stray Children as a retro-inspired RPG scenario in which a curious boy is drawn into an unreleased console game and awakens in a world inhabited only by Children.
Outside a protective stronghold, monstrous adults called The Olders embody the burdens and anxieties of adulthood.
Players engage in turn-based encounters with these Olders and can choose between combat or dialog-driven options that use words to affect opponents.
The developer frames the title as an exploration of emotional wounds and interpersonal reconciliation within a surreal, nostalgic RPG setting.
Stray Children is available on Nintendo Switch, and the Treasure Box is offered as a limited physical collector’s edition for the Japanese market with a December 10, 2026 street date.
Retailers in Japan are taking pre-orders for the Treasure Box edition; interested buyers should check official store listings and authorized retailers for availability and regional details.
The standard physical edition is also part of the announced release strategy.
This announcement underscores ongoing demand for physical collector editions on Nintendo Switch and highlights Onion Game's approach to packaging narrative-driven indie titles with curated physical extras.
For players who prioritize language accessibility, the confirmed support for English via system settings is a notable detail for import-minded fans.
