The full story
Biography
Momotaro’s route to Kyoto was unusually well traveled. Born to Biju and Momoko at Ueno Zoo, he moved with his mother to Chiba as a two-year-old, returned to Ueno in 2008, and then transferred to Kyoto in 2010. The move paired a young Japanese-born male with Genki, an experienced female from Kyoto’s long-running gorilla line.
His restless curiosity became part of his public personality: zoo records describe a gorilla who runs, climbs, tumbles, drums on walls, and notices people moving outside the enclosure. Keepers also describe a more tender adult behind the spectacle: patient, kind, slightly awkward, and willing to play through the keeper window. With Genki, he has raised three sons and grown from an energetic newcomer into the steady silverback of a multigenerational family.
