Ryō

The is the currency used in the Naruto world. It's based on an old Japanese gold coin used in Japan before the Meiji period. It was later replaced by the Yen. In the Official Fan Book: Hiden: Hyō no Sho, Masashi Kishimoto gives an exchange rate of 10 yen to a ryō.

Although money is not so much focused on in the story, certain prices and sums of money have been mentioned. For example, Asuma Sarutobi has a price on his head of 35 million ryō, five million ryō more then his fellow former Guardian Ninja, Chiriku.

Another example is missions. Shinobi usually earn their money by doing missions. The rewards for these range from five thousand ryō for a simple D-rank mission to more than a million ryō for an S-class mission.
