The Japanese verbal noun '両替 (りょうがえ)' refers to the act of exchanging one form of currency for another, such as converting yen to dollars or vice versa. It is commonly used in contexts involving money exchange, such as at banks, airports, or currency exchange offices. For example: I exchanged yen for dollars「円をドルに両替しました」(えんをドルにりょうがえしました). Where can I exchange money?「どこでお金を両替できますか?」(どこでおかねをりょうがえできますか?). This term is specific to currency exchange and does not apply to other types of exchanges.
