Year on Japanese coins is the the year of the current emperor's reign followed by his name.Prior to 1948 regnal numbers are read from right to left.Examples: Emperor (Mutsuhito) regnal year from R to L = 2 x 10 6. Emperor (Yoshihito) regnal year from R to L = 10 1. After 1948 (reform coinage) regnal numbers are read left to right. It is not that easy, considering that there are various ways to state the date.Though standards are being introduced, some countries have different orders. the date starts with the day, then the month and last the year.
