What was the Japanese airdate of the first Pokémon anime episode?

The first Pokémon anime episode, “Pokémon, I Choose You!”, aired in Japan on April 1, 1997.

Broadcast on TV Tokyo, the episode introduces Ash Ketchum as he begins his journey from Pallet Town. Professor Oak gives Ash a Pikachu instead of one of the conventional starter Pokémon, setting up the relationship that became central to the animated series.

The episode also establishes several recurring elements, including Pokémon battles, the Pokédex, wild Pokémon encounters, and Ash’s rivalry with other Trainers. Its ending features a flock of Spearow and a mysterious Ho-Oh, a Pokémon not included in the original game’s Pokédex at the time.

The English adaptation appeared later, beginning in the United States in 1998. The Japanese first episode remains distinct from later anniversary films and specials, even though a 2017 movie used the same title.
