Commerce (TCG)

Commerce in Rokugan was based on the land tilled by farmers and protected by the samurai. A yearly stipend of rice formed the basis for currency in Rokugan: koku. Legend of the Five Rings - Roleplaying, p. 10
== Coinage ==
At the beginning of the Thousand Years of Peace innovations in agriculture allowed the population of the Empire to grow, and so did trade. Merchants found the system of barter limiting, however. In many areas, small plates or bars of gold or jade were used in place of actual goods, but they were subject to problems of size variation and falsification. Coins facilitated trade between merchants, and the Emperor declared that the koku would represent the amount of rice needed to feed a person for one year. Coinage allowed merchants to easily buy and sell their goods. Emerald Empire: The Essential Guide to Rokugan, p. 13
== Patronage ==
Trade and commerce were considered dishonorable for samurai to involve themselves in such mercantile pursuits. They left monetary matters to non-samurai, who in turn sought the patronage of a powerful lord. 
== Roads ==
To travel the on its few roads, samurai must obtain special papers and pay a tax toward their upkeep. Merchants' carts and horses were banned from the Imperial highways altogether, forcing them to rely on special trade routes to carry goods between cities.
