To find them, you first have to figure out how to read the dates. Dates are expressed as years elapsed from a base date.

In our example below, year 25 is 1936AD, and year 31 is 1942.

Calculating the Gregorian Date Once you know the era name and year, you can calculate the Gregorian year using the era table above.

Take the era's starting year, add the era year, and subtract 1.

For example, 1989 was the first year for the current Heisei era (under Emperor Kinjo, or Akihito), so coins minted that year would contain the symbol for the Heisei era (平成) and the symbol for 1 (一). It begins with the symbols for the era name (see the list above), followed by the era year, and ends with the symbol for year (年).Instead, Japanese uses combinations of numerals which add and/or multiply to the number being written.For example, 11 is not written 一一 (1 1) - it is 十一 (10 1, or 10 1). 20 is 二十 (2 10, or 2 * 10), and 22 is 二十二 (2 10 2, or 2 * 10 2).The position of a symbol doesn't define its value; its effect on or by its neighbors does. Modern Japanese coins, however, use the Japanese era calendar to indicate when a coin was minted.More examples of Japanese numbers: 32: 三十二 44: 四十四 78: 七十八 99: 九十九 Japanese Dates In the late 1800s, Japan adopted the Gregorian calendar, but with a starting date (a "year zero") that corresponded to the Gregorian calendar's year 660 BC, making Japan's year values larger than the year used by other countries (i.e. An era starts counting years at 1 with each new Japanese emperor.
