Doko Demo Issho

The PocketStation's most popular game was Dokodemo Issho, which sold over 1.5 million copies in Japan and is the first game to star Sony's mascot Toro. The PocketStation was discontinued in July 2002 after having shipped nearly five million units.

Toro, also known as the Sony Cat, is a fictional character created by Sony Computer Entertainment.

The character, an anthropomorphized Super Deformed design style white cat, is characterized by its big, trapezium-shaped face, a rectangular-shaped body, and its vast variety of face expressions.

It first appeared in July 1999 as the main character (chatterbot) in the video game Doko Demo Issyo (also written as Doko Demo Issho, meaning "Together everywhere") on the miniature game console called PocketStation, produced by the same company.
