Which Japanese magazine announced the 1996 promotional offer for the secret Pokémon Mew?

CoroCoro Comic announced the 1996 promotional offer for the secret Pokémon Mew.

Mew had been added to Pokémon Red and Green as a hidden species and was not obtainable through normal gameplay. In April 1996, CoroCoro Comic publicized a promotion centered on the mysterious Pokémon, inviting readers to enter a lottery for the chance to have Mew placed on their cartridge.

The promotion helped transform Mew from an unused secret into a subject of intense player interest. Nintendo and Game Freak later distributed Mew through official events, but the first widely publicized opportunity came through CoroCoro’s reader promotion.

The magazine was especially influential because it targeted Japanese children and regularly featured Pokémon material, including game news and manga. The offer is sometimes incorrectly attributed to Nintendo Power or to the anime, but neither was the publication that announced this original Japanese Mew lottery.
