Have you ever wanted to buy milk but were confused by the many different types of similar paper cartons on the shelves of supermarkets and convenience stores? Milk is actually classified and sold in various ways depending on the processing method. Here are some examples of the different types:

Milk: Raw milk that has been heat pasteurized without adding water or additives.
Ingredient-adjusted milk: Milk with ingredients that have been adjusted by removing some of the milk components (water, milk fat, minerals, etc.) from the raw milk.
Processed milk: Raw milk that has been processed by adding dairy products such as skimmed milk powder, cream, and butter to the main ingredients.

For "milk" cartons, as you can see in the picture, there is a small indentation on the top of the carton, which is easy to find even if you can't read Japanese. This is useful to remember. (Not all "milk" products have this indentation, but those that do are definitely "milk" and can be used as a guide for making decisions.)
