There are bento sold throughout Japan (in convenience stores open day and night, on trains, in restaurants dedicated), but family tradition has it that the Japanese wife or mother lovingly prepares for her husband and children the bento lunch. The preschoolers have no canteen and bring their lunch each day. In this case, the bento is often decorated with ornaments shaped characters Kawaii (cute in Japanese) called charaben, short for "character bento," which made ​​their reputation. There are so many specialized accessories such as egg molds to easily represent cubs, rabbits or other.
