Kakku (火9) is a Japanese abbreviation for Kayō Ku-ji (火曜9時), meaning Tuesday at 9PM. This is a popular time-slot which airs Japanese television dramas. Kakku is Fuji TV's second best-rated time-slot for TV dramas, behind Getsuku (Monday at 9PM). Prior to airing dramas, the time-slot was occupied by the popular quiz show Naruhodo! The World, which ran for a period of fourteen years. The first drama to air on this time-slot was Minikui Ahiru no Ko (1996), starring Goro Kishitani and Takako Tokiwa.
