Re‑Ment Lists Pokémon Terrarium Collection 10 for Sept. 21 Japan Release — 30th‑Anniversary Collectible, Not a Game

Re-Ment has officially listed a new Pokémon Terrarium Collection 10 — Pokémon 30th Anniversary ver. set, a physical collectible release tied to the franchise’s 30th anniversary in 2026. On Re-Ment’s official product page, the Japan release date is listed as Sept. 21, 2026, while retailer preorder pages are pointing to an October 2026 arrival in the U.S. and other international markets.

The key clarification: this is not a new Pokémon video game. Re-Ment is a Japanese collectibles maker, and its Pokémon Terrarium line is an existing series of miniature display pieces packaged as small diorama-style scenes.

Re-Ment’s listing uses the Japanese name “Pokémon テラリウムコレクション10 ポケモン30周年記念ver.”, which translates to Pokémon Terrarium Collection 10 — Pokémon 30th Anniversary ver. The page lists a price of 1,650 yen and says the release includes six types in the set. The product branding places it squarely within Pokémon’s wider 30th anniversary merchandise push rather than any software announcement.

The October 2026 timing now circulating online appears to come from retailer estimates, not from Re-Ment itself. Stores including BigBadToyStore have posted preorder pages for the same item with an estimated October 2026 U.S. arrival. Re-Ment’s own page, however, lists only the Japanese release date and does not provide a separate confirmed U.S. launch date.

That distinction matters because the phrase “Pokémon Terrarium” can sound like a game title out of context. In practice, Re-Ment has used the Terrarium label for years on Pokémon-themed collectible mini-scenes sold as merchandise. The new set’s “30th Anniversary ver.” branding appears to be what is driving fresh attention and broader retailer listings.

Some readers may have encountered more ambiguous wording elsewhere online. A Steam community news post, for example, used the headline “Pokémon Terrarium Officially Announced For October 2026.” But based on the official Re-Ment product page and matching retailer listings, the announcement is for a collectible figure-and-diorama line, not a game reveal. Separately, Pokémon’s 30th anniversary plans also include the previously announced Pokémon Winds and Pokémon Waves for Nintendo Switch 2 in 2027, but that is a different announcement entirely.
