Yen investment is booming! NT$ to JPY exchange rate reaches 4.85. Four ways to exchange currency revealed

December 2025, the Taiwan dollar has surged to 4.85 against the Japanese Yen, an overall appreciation of 8.7% since the beginning of the year at 4.46. With the resurgence of travel to Japan and the Yen’s appeal as one of the world’s three major safe-haven currencies, more and more Taiwanese are planning to exchange for Yen. But the question is: what’s the most cost-effective way to exchange? Can it be done in 5 minutes, or does it require an hour?

Why Exchange Yen Now

Travel and Living Needs

Japan still relies heavily on cash, with only 60% credit card penetration. Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, cash remains king. Online shoppers and purchasing agents often need to pay directly in Yen, and students plan their currency exchange in advance to avoid sudden fluctuations.

Financial Hedging Value

The Yen has long been one of the top three global safe-haven currencies (alongside USD and Swiss Franc). During market turbulence, funds flow into Yen—during the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a week, effectively buffering stock market declines. For Taiwanese investors, exchanging Yen is not just for leisure but also a strategic tool to hedge against Taiwan stock market risks.

Interest Rate Differential Trading Opportunities

Japan maintains ultra-low interest rates (0.5%), making Yen a “funding currency.” Investors can borrow Yen at low interest, convert to higher-yield USD investments, with a USD/JPY interest rate spread of 4.0%. When market risks increase, they can close positions by buying back Yen, cycling for arbitrage.

Is it worthwhile to exchange Yen now? The answer is “gradual entry”

Recently, the Bank of Japan’s hawkish comments have pushed expectations of rate hikes up to 80%. Governor Ueda Kazuo indicated that the December 19 meeting is expected to raise rates by 0.25 basis points to 0.75% (a 30-year high), with Japanese bond yields reaching a 17-year high of 1.93%. USD/JPY has fallen from the high of 160 at the start of the year to 154.58 now, with short-term rebounds possibly to 155, but medium to long-term forecasts suggest it will stay below 150.

For investment purposes, the short-term risk for the Yen is in arbitrage position unwinding, with potential fluctuations of 2-5%. It is recommended to enter gradually, avoiding a full exchange at once. In the second half of the year, Taiwan’s currency exchange demand increased by 25%, mainly driven by travel recovery and hedging needs, reflecting strong market demand for Yen.

Comparison of 4 Exchange Methods

Option 1: Airport or bank counter exchange (fastest but most expensive)

Bring cash in TWD to a bank or airport counter to exchange for Yen cash. Time cost: 10-15 minutes.

The obvious downside—using “cash selling rate,” which is 1-2% worse than the spot rate. For example, Taiwan Bank’s rate on December 10, 2025, is about 0.2060 TWD/Yen (1 TWD = 4.85 Yen). Some banks also charge handling fees (e.g., E.Sun, E.Sun Bank, each 100 TWD; Cathay United Bank 200 TWD).

Exchanging 50,000 TWD could result in a loss of about 1,500-2,000 TWD. Suitable only for urgent or small amounts.

Option 2: Online exchange + in-person withdrawal (balanced approach)

Use bank app or online banking to convert TWD to Yen and deposit into a foreign currency account, enjoying “spot sell rate” (about 1% discount). When cash is needed, withdraw in person or via foreign currency ATM, incurring cross-bank fees of 5-100 TWD. Total time: 2-3 hours with batching (including waiting).

E.Sun Bank app allows exchange and withdrawal of Yen cash with a minimum fee of 100 TWD. Suitable for monitoring exchange rates and entering gradually at low points for an average cost. Exchanging 50,000 TWD could lose 500-1,000 TWD, cheaper than in-person exchange.

Option 3: Online currency settlement + airport pickup (most recommended before travel)

No need for a foreign currency account. Simply fill in currency, amount, pickup branch, and date on the bank’s website, then bring ID and transaction notice to pick up in person. Taiwan Bank’s “Easy Purchase” online settlement is fee-free (pay via TaiwanPay for only 10 TWD), with about 0.5% better rate. Booking can be completed within 1-3 days before departure, and pickup takes about 10 minutes.

Taoyuan Airport has 14 Taiwan Bank counters and 2 24-hour branches, allowing direct pickup before departure without hassle. Exchanging 50,000 TWD results in a loss of 300-800 TWD, ideal for planned travelers.

Option 4: Foreign currency ATM 24/7 cash withdrawal (best for emergencies)

Use a chip-enabled bank card to withdraw Yen cash from foreign currency ATMs, available 24/7 and supporting interbank transactions (only 5 TWD cross-bank fee from TWD account). E.Sun Bank’s foreign currency ATMs allow withdrawal of Yen from TWD accounts, with a daily limit of 150,000 TWD and no exchange fee. Only 5-10 minutes needed.

Disadvantages include limited locations (about 200 nationwide), fixed denominations (1,000/5,000/10,000 Yen), and possible cash shortages during peak times. Exchanging 50,000 TWD could lose 800-1,200 TWD, suitable for urgent needs or those unable to visit a counter.

Note: ATM withdrawals in Japan will be adjusted by the end of 2025, requiring international cards (Mastercard/Cirrus).
