"1円" (one yen) is the smallest denomination of currency in Japan, represented by the symbol "¥" and the code "JPY." It is a coin made of aluminum and has a simple design featuring a paulownia tree on one side. The value of 1 yen is very low, making it primarily used for small transactions or as a rounding figure in pricing. In the context of the Japanese economy, 1円 plays a role in everyday purchases, although it is often considered less significant due to inflation. Coins of 1円 are commonly found in wallets and are sometimes used in vending machines or for small items in stores.
