Used in Japan during the Heian period (794-1185), Jubako Bento (重箱) means “Layered Bento Boxes”. Similar to traditional bento boxes they are a combination of elaborately decorated lacquered boxes used for holding and presenting food on outings or special occasions.
The upper-classes traditionally used Jubako Bento to hold takeaway meals for picnics, birthdays, celebrations and special occasions. They were stacked before and after serving the dinner and also used for holding Osechi-ryōri (御節料理) foods in for traditional Japanese New Year celebrations.
