Wonder Project J2 is a 1996 life simulation video game developed by Givro Corporation and originally published by Enix for the Nintendo 64.

Wonder Project J2 is a bishōjo life simulation game similar to its predecessor, where the player communicates with Josette through her robot, Bird. The player answers her questions on-screen by selecting "yes" or "no". Josette cannot hear or see the player, but learns about the player through successive binary questions. She recalls the answers later throughout the story. The player can command Josette through Bird, though she does not always listen. Player advancement through the game is dependent on how well their teachings mesh with other activities on the island. After teaching Josette a series of fundamental human interactions, the plot-driven second chapter guides Josette through a series of hardships and confrontation with the Siliconian Army.
