Bokura no Kazoku[b] is a 2005 simulation video game developed by Millennium Kitchen and published by Sony Computer Entertainment for the PlayStation 2.

In Bokura no Kazoku, the player assumes the role of a newlywed couple in their early thirties living in contemporary Koenji, a residential area in Tokyo.

[4] Ayabe stated that inspiration for Bokura no Kazoku came from the birth of his first child, which occurred shortly after development on the first Boku no Natsuyasumi concluded.

[2] Ayabe and Millennium Kitchen spent two years on location scouting and interviewing subjects throughout Koenji and Tokyo, taking approximately 25,000 reference photos to create the game's environment.

As in that game, the visual style of Bokura no Kazoku is characterized by a juxtaposition of Ueda's cartoonish character designs against realistic pre-rendered backgrounds.
