December has more than one date.

Japan art books: Friday, December 18

Pokémon Japan and OVERLAP list the same publication date for BOOK1, BOOK2 and BOOK3: December 18, 2026. Each volume is sold separately. The date is a Japan-market publication schedule, and the announcement says details may change. Pokémon Japan announcement; OVERLAP special page.

The calendar download records an all-day Japan publication event. No release-hour announcement was established. Depending on your calendar app, an all-day entry stays on that calendar date rather than converting into an invented midnight launch in your location.

A publisher’s date does not establish dispatch, international arrival or current preorder acceptance. Keep the seller checklist with any reminder you save.

A separate December product: the US TCG binder

The official US product showcase lists the Pokémon TCG: 30th Celebration Binder Collection for December 4, 2026. It contains a nine-pocket binder and five 30th Celebration booster packs. The expansion itself launched on September 16. US product showcase; expansion launch announcement.

The official UK binder gallery lists September 2026 and does not provide a precise day in the text checked. A US December date should not be carried over to a UK listing. No exact date for every other market has been established here. UK binder gallery.

These TCG records were readable through official indexed text where direct pages returned a security iframe. This guide does not invent the reason for a date difference, a delay history, current stock or an official retail price.

What the dates do not announce

The art-book publication is not a new video-game launch, and its listed game coverage does not promise a bundled game, DLC code or trading card. No such inclusion was established in the art-book records.

The phrase “30th anniversary December release” can describe different products. Use the Japanese ISBN for a book order, or the full TCG product name and market for a card-product order. The source register keeps those records separate.
