No, it's not a game.
It helps the autistic and developmentally disabled to communicate with others.
For example, people who can't speak or read, can just tap pictures that will let them tell other people what they want, etc.
It supposedly has several different modes of communication that people can use, depending on their handicap.

Sweet jeebus it retails for
15,750 yen
Not surprising though, as it's highly-specialized software for a very small market.

Wow, I can't even google this game. Anything that comes up is related to the ROM release and there's no actual game info or screenshots.
To Google this title you have to do it in Japanese.
