Los años bisiestos del calendario japonés se corresponden con los mismos años bisiestos del calendario gregoriano.Leap years in the Japanese calendar correspond to the same leap years in the Gregorian calendar. Un año bisiesto en el calendario gregoriano se define como un año gregoriano que es divisible por cuatro, excepto si es divisible por 100.A leap year in the Gregorian calendar is defined as a Gregorian year that is evenly divisible by four, except if it is divisible by 100. Sin embargo, los años gregorianos que son divisibles por 400 son bisiestos.However, Gregorian years that are divisible by 400 are leap years. Un año común tiene 365 días y un año bisiesto tiene 366 días.A common year has 365 days and a leap year has 366 days.

Un día bisiesto es un día que solo se produce en un año bisiesto.A leap day is a day that occurs only in a leap year. Por ejemplo, el 29 día de Gatsu (febrero) es el único día bisiesto.For example, the 29th day of Nigatsu (February) is the only leap day.
