正月
Osechi-ryōri (御節料理, お節料理 or おせち) are traditional Japanese New Year foods. The tradition started in the Heian period (794–1185). "Osechi" are easily recognizable by their special boxes called "jūbako" (重箱), which resemble "bentō" boxes. Like "bentō" boxes, "jūbako" are often kept stacked before and after use.
