Koban (coin) facts for kids
The Koban was a special oval-shaped gold coin used in Japan a long time ago. It was first made by order of a powerful leader named Tokugawa Ieyasu during the Edo period, specifically in the Keichō era. This coin was an important part of the money system used by the Tokugawa government.

What Was the Koban?
The Start of Japanese Gold Coins
The first koban coins were made in the year 1601. This marked the beginning of a new system of money for the Tokugawa government. Each koban coin was worth one ryō, which was a standard unit of value at the time. Even though there were other gold and silver coins, the government worked hard to make sure the koban kept its value steady. By the end of the 1600s, one koban was reliably worth one ryō.
Today, you can sometimes find cardboard versions of koban covered in gold foil. These are sold as Engimono (縁起物), which are like lucky charms or talismans, often found at Shinto shrines.
Koban in Daily Life and Trade
Before the mid-1800s, Japan's economy mostly relied on rice. The main way to measure wealth was the koku, which was the amount of rice needed to feed one person for a whole year. Farmers paid their taxes in rice, and important officials were also paid in rice.
However, when people from other countries, like the Portuguese, came to Japan in the 1550s, they preferred gold over rice for trade. The koban, which was considered equal to about three koku of rice, quickly became the preferred coin for trading with foreigners.
Challenges to the Koban's Value
Over time, some local lords started making their own koban coins. They often made these coins less valuable by mixing in cheaper metals with the gold. This made the coins "debased." The central government in Edo tried to fix this with many new rules about money. But often, these new rules also ended up making the koban less valuable.
To make things even more confusing, fake koban coins, called "counterfeits," also started to appear after each new rule. These fake coins were sometimes only slightly less valuable than the real ones. By the time Commodore Matthew C. Perry visited Japan in 1853, some merchants even preferred the older, fake koban coins because they had more gold than the newly made official ones!
The End of the Koban Era
A big change happened in Japan in 1868, known as the Meiji Restoration. This event brought many modern changes to the country. One of these changes was a new system for money, similar to what was used in European countries. Because of this, the koban coins were no longer made and were eventually replaced by new currency.
