Tamagotchi

Tamagotchi (Japanese: たまごっち; IPA: [tamaɡotꜜtɕi], "Egg Watch") is a brand of handheld digital pets marketed since 1996 by Japanese toymaker Bandai, a division of Bandai Namco Holdings. Most Tamagotchi are housed in a small egg-shaped handheld video game with an interface consisting of three buttons, with the goal of raising the pet as it goes through different life stages.

The original Tamagotchi, released locally in 1996 and worldwide in 1997, quickly became a major global toy fad for a period of time. Tamagotchi was brought back in 2004 and since then has received more new versions while Bandai has also expanded the franchise to other media and merchandise. As of 2025, over 98 million units have been sold worldwide. It has been a staple children's toy in Japan since its early years.

According to Bandai, the name is a portmanteau combining the two Japanese words tamago (たまご), which means "egg", and uotchi (ウオッチ) "watch". After the original English spelling of watch, the name is sometimes romanized as Tamagotch without the "i" in Japan. Most Tamagotchi characters' names end in tchi or chi (ち) in Japanese, with few exceptions. "Mametchi", present since the original release, became a mascot of sorts for the series.
