A grandmother made entirely of computer code teaches a kid that technology isn't magic, just a different kind of thinking. The song makes it simple enough for a five-year-old to get, genuine enough that adults don't roll their eyes. One minute of pure comfort dressed up as science fiction, the kind of thing you show someone when they're scared of the future.

Computer Obaa-chan is a children's song performed by the NHK Tokyo Children's Choir and presented as a single music video in NHK's Minna no Uta segment. Its listed genres are adventure, comedy and science fiction, which suggests a playful, lighthearted piece for young audiences built around a grandmother and computers.
