The Wadōkaichin Loyalty Programm

Welcome to Yumei's Wadōkaichin Loyalty Programm

What does  Wadōkaichin means ? 
Wadōkaichin (和同開珎) are Japan's first government-issued coinage, minted during the Nara period (708-715 AD) under the reign of Empress Genmei. The name "Wadōkaichin" translates to "currency of Wadō," referring to the Wadō era (708-715) during which they were introduced.
So in Short Term Yumei will use "Wado" as Loyalty Coins !
