As of December 10, 2025, the Taiwanese dollar has reached 4.85 against the Japanese yen, hitting a new high this year. Starting from 4.46 at the beginning of the year, the yen has appreciated by over 8% within the year. For investors looking to exchange currency, this is an unmissable opportunity. But what's the most cost-effective way to exchange? We will explain the latest four currency exchange channels once and for all, helping you save unnecessary expenses.
Why exchange yen now?
The yen is no longer just pocket money for travel; it has three layers of value.
Travel and daily consumption
Shopping in Tokyo and Osaka, skiing in Hokkaido, vacationing in Okinawa—most Japanese merchants still prefer cash (credit card penetration is only 60%). Purchasing agents, online shopping, studying abroad, and part-time work all require direct settlement in yen.
Hedging asset status
The yen ranks among the world's three major safe-haven currencies (along with the US dollar and Swiss franc). During the Russia-Ukraine conflict in 2022, the yen appreciated by 8% in a week, effectively buffering stock market declines. For Taiwanese investors, exchanging for yen is equivalent to adding to the Taiwanese stock market.
