Osechi-ryori are traditional Japanese New Year foods. The tradition started in the Heian Period. Osechi are usually recognizable by their special boxs called Ju-bako. These dishes are broiled, dried and give strong a flavor to keep for a long time. My family make Osechi every year but people buy that recently. The most difficult food is Kuri-kinton because we should mash and filter sweet potatos to make this. It is very heavy work but Kuri-kinton is necessary food in New Year.
