This Ooyama's Pikachu card in the rare Green Version marks a notable piece from the early Pokémon trading card era, which began its monumental rise in the late 1990s, coinciding with the original anime's debut in 1997.

Produced during a time when card print runs were less standardized, this variant is particularly sought after due to its limited release and distinctive coloring, appealing to both nostalgic collectors and serious Pokémon enthusiasts.

Cards from sets like this, often associated with unique artistry, remain highly coveted, especially in negotiable condition as conditions directly influence market pricing, which is currently robust at ¥500,000 for comparable quality.

As an authentic Japanese release, this card benefits from both its provenance and the careful preservation typically seen in domestic collections, reinforcing its desirability within the collector community.
