Kanshū Nippon Jōshikiryoku Kentei Kyōkai: Imasara Hito ni wa Kikenai Otona no Jōshikiryoku Training DS (JPJapanese: 監修 日本常識力検定協会 いまさら人には聞けない 大人の常識力トレーニングDS
Romaji: Kanshū Nihon jōshiki ryokukentei kyōkai imasara hitonihakikenai otona no jōshiki-ryoku torēningu DS) is a Nintendo DS video game better known as General Knowledge Training and Common Sense Training in western territories. The game was never released outside of Japan. The game was developed by HAL Laboratory, published by Nintendo, and supervised by the Japan Common Sense Aptitude Examination Association. It was released as part of a Touch Generations video game and was released in 2006. The game is based around proper manners, a users' intelligence, and other topics. Like Brain Age: Train Your Brain in Minutes a Day!, you'll only be able to partake in the activities a little bit each day, and afterwards you'll be given a stamp no matter how well you performed.
The game did extraordinarily well in the market. Despite only being released in Japan, the game managed to sell a total of 1.53 million copies to date. In the first week, the game almost sold 200,000 total copies and was at the top of the charts for quite some time.
