The items, billed as Mega Raichu X and Mega Raichu Y, were described by the company as character merchandise tied to in-game appearances in the Mega Dimension DLC for Pokemon Legends Z-A.
The announcement sets official online and in-store release windows for Japan and points to international ordering options via Amazon Japan.
According to the release, the Pokemon Center Online Store will carry the Mega Raichu X and Mega Raichu Y plushies beginning on May 21, 2026.
Fans wishing to purchase in person can visit Pokemon Center retail locations in Japan starting May 23, 2026.
The Pokemon Company also indicated that international customers should be able to order the plushies from Amazon Japan close to the launch dates, providing a route for overseas collectors to secure the items.
In journalistic terms, the company stated that fans will be able to purchase the new Mega Raichu plush lines from the Pokemon Center Online Store on May 21 and from Pokemon Center stores across Japan on May 23, with Amazon Japan expected to provide international fulfillment around the same time.
That phrasing clarifies availability windows and the suggested international purchase channel.
Pokemon Center Japan is the official retail arm for Pokémon-branded merchandise and regularly releases exclusive plushies and collectibles tied to game content.
While plush distribution will be handled through Pokemon Center outlets and retail partners, the Pokémon franchise's downloadable content and game updates have traditionally been distributed through the Nintendo eShop for the Nintendo Switch platform, reflecting how in-game appearances often drive merchandise demand.
For collectors and retailers, key dates are May 21, 2026 (Pokemon Center Online Store) and May 23, 2026 (in-person Pokemon Center stores in Japan).
International buyers should monitor Amazon Japan listings as the dates approach.
