Toilet Number Final Year reaches its finale. This time, the filming location is Yamanashi and Shizuoka Prefectures at the foot of Mount Fuji. Five girls raised on the region's fresh air and pure water are all healthy and full of vitality. In this shoot, they each defecated in front of four cameras. This installment also includes scenes of the girls eating local specialties such as "hoto" and curry, clearly demonstrating the direct relationship between how much one eats and how much one defecates.
