I have many of the japan peso from 1 peso to 100 peso are they worth anything?

Question

some of the bills are uncirculated, some of the money is written in all japanese and are not pesos, some centavos

Answer 1

Sorry, but in Japan the currency used is the yen, not the peso.  To find out what you have, show it to someone who travels a lot or to a bank where they do foreign exchange.

Once you know what currency you have, you can find out the value.  If it is an older form of currency, it may have additional value to collectors.  In any case, it should still have the original value as money.
