Koku

The koku was the standard unit of monetary measure in Rokugan. Its value was equal to the amount of rice that would feed a man for one year, roughly five bushels of rice. Legend of the Five Rings; Third Edition, p. 38
== Worth of a Koku ==
During the Dawn of the Empire heimin piled sacks of rice in a square at Otosan Uchi, and it was agreed about how many represented a koku. This arch, called Daikoku's Arch was built over the sacks, so that the measurement within would never be lost. Otosan Uchi:Book 1, p. 52
=== Variable Worth ===
The koku was based upon a year's harvest, so the value of items could fluctuate wildly from year to year, making it difficult to anticipate the cost of goods and services (other than rice) from year to year. Secrets of the Crane, p. 35
== Invention ==
The coin used for the koku was invented and designed by Yasuki Tanaka in 243. The design of his coin featured the kanji of the Fortunes on one side and the Kami on the other. A hole ran through the center of the coin, which allowed for the coins to be strung for easy carrying and counting. The original design was still used to this date. Made of gold, it was simple and recognizable, but confounded most attempts at forgery. Legend of the Five Rings; Third Edition, pp. 11, 181
== Implementation ==
At first, the coin was used exclusively by the Crane Clan, but eventually the Emperor asked about the little copper coins. In response, Tanaka gave the Emperor the minting plates for the coins as a gift. 
== Smaller Denominations ==
One koku could be broken into five smaller silver coins known as ichibukin, or more commonly known as bu. A bu could be further broken down into ten copper coins known as zeni. 
== Minting ==
Each clan minted their own coinage, and used distinctive marks on them so the value of a Lion farm would not be confused with that of a Crane farm. The theory was that the coins could be redeemed for an amount of rice equal to their value at any time, although this practice was rarely enforced. The coins remained in circulation, and would be more commonly used as a medium of exchange.
