And the second one is a Panama dime. The Japanese coin is a silver ¥100 dated Showa 31 (1956) - the first year of that design.
No, it's a dime. KM#10a, cu-ni clad copper. Un Decimo is 1/10th of a Balboa, and the fixed exchange rate is 1 Balboa=US$1. In fact, US currency circulates as legal tender in Panama.
