What was the Japanese title of the 1998 Nintendo 64 game known internationally as Pokémon Stadium?

The Japanese title of the 1998 Nintendo 64 game known internationally as Pokémon Stadium was Pocket Monsters Stadium.

Nintendo released Pocket Monsters Stadium in Japan on August 1, 1998. It was a 3D strategy role-playing game developed by Nintendo EAD and built around Pokémon battles on the Nintendo 64. The game used a smaller selection of Pokémon than the full Game Boy roster and was released only in Japan.

The title can cause confusion because a later, expanded game was released internationally as Pokémon Stadium. That 1999 Japanese release was itself known as Pokémon Stadium 2 in Japan, while the Western version became the first Stadium title released outside Japan.

The later international Pokémon Stadium supported compatibility with Pokémon Red, Blue, and Yellow through the Transfer Pak. The Japan-only 1998 game is historically important as the earlier Nintendo 64 entry, but its title and release history differ from the better-known Western game.
