The Japanese New Year (正月, shōgatsu^?) is an annual festival with its own customs. The preceding days are quite busy, particularly the day before, known as Ōmisoka. The Japanese New Year has been celebrated since 1873 according to the Gregorian calendar, on January 1 of each year (New Year's Day where the Gregorian calendar is used). In Okinawa, the cultural New Year is still celebrated as the contemporary Chinese, Korean, and Vietnamese New Years.
