Asahi is introducing a nutrition drink (350 ml PET bottle) which is low calorie and contains no fat, but has the same calcium as 200 ml of milk. The packaging is designed to remind you of milk. Just having the same amount of calcium in a drink is no guarantee that the same amount will be absorbed by the body, and 157 yen is expensive for a 350 ml bottle. That is the same price as most 500 ml PET bottle drinks.
It does have fewer calories than milk, but I would rather pay 100 or 110 yen for 200 ml of milk.
