In 1990, Japan ushered in a new emperor's era with the start of the Heisei period.

Learning from this, the government limited the Heisei coin's issuance to 2,000,000 units, intending to preserve its value. This strategic choice was highly acclaimed for maintaining the coin's value while commemorating an important historical event for the nation.
