Originally, hatsumoude had been called "toshigomori". It was a custom that the head of family stay in the shrine from night on New Year Eve to morning on New Year's Day for prayer. In Meiji period, toshigomori had divided into "jyoyamoude" that was done at night on New Year's Eve. Also "ganjitsumoude" that was done in morning on New Year's Day. So "ganjitsumoude" is the original form of today's hatsumoude.
