Tuttuki Bako was developed by Bandai in 2008. It was released only in Japan at a retail value of $30, and it is manufactured in China. It comes in three colors - red, black, and lime green. In the months prior to its release, Japanese advertisements for the Tuttuki Bako playfully emphasized risqué double entendres relating to the insertion of the player's finger into the box. This innuendo did not go unnoticed in the international community and some English-language reviews reflect similar humor.

The game was generally well-received internationally where it was described as "delightfully inexplicable" and "wonderfully weird." The game was also compared favorably with Bandai's earlier Tamagotchi line. Although some reviews described the Tuttuki Bako as "a bad idea" or "useless and barely entertaining," the same reviewers were often quick to point out exonerating aspects such the device's inherent interestingness and the retro-feel of the system. One negative aspect of the game that reviewers noted was its relatively steep import cost in the range of $50–$70 USD. Because the game was released only in Japan, international players had to go through importers and Tuttuki Bako's sales price tended to reflect increased shipping/handling as well as third party markup.
