Ganbaru Watashi no Kakei Diary (JP) is a Nintendo DS video game released in 2007 bySyn Sophia and Nintendo. The game was released exclusively in Japan and was part of the Touch Generations series. The game assists the player in planning a household budget and is controlled via the touch screen. There are eighteen categories in which you can manage your budget, the categories ranging from things like food, to entertainment to fashion. There is a mode contained in the game that helps players plan for a loan.

After the game was released, it was reported that two calculators in the game that multiplied and divided fractional numbers didn't work appropriately. The Namco video game Taiko no Tatsujin DS was also reported to not work correctly either. Both companies offered replacements of their games, with the replacement of Ganbaru Watashi no Kakei Diary being found at an official Nintendo website (which can be accessed here.).
