Labor Thanksgiving Day is observed in Japan every November 23, commemorating labor and production. This holiday has its roots in the ancient cereals festival known as Niiname-sai, which dates back to rituals believed to have been developed during the rule of Emperor Jimmu around 660-585 BC. The festival was more formally celebrated during Emperor Seinei's reign in 480-484 AD, with historical records from Emperor Temmu's time (667-686 AD) documenting its significance. After World War II, the Niiname-sai festival became exclusive to the Imperial House of Japan, while the public now celebrates Labor Thanksgiving Day. On this day, people are encouraged to reflect on the environment, human rights, and peace, with children often creating drawings to present to local police stations.
