Osechi
The beginning of osechi starts in the Yayoi period. This went from 1000 BC to 300 AD. People at that time were starting to grow rice. As part of a harvest festival, called Sekku, people made food gifts to please the gods. Sekku foods are eaten to thank the gods for the blessing of nature, a good harvest and big catch. This is the beginning of osechi. This idea came from China.
