2025 NT Dollar to Japanese Yen Exchange Strategy: End-of-Year Appreciation of 8.7%, Which of These 4 Methods Is the Most Cost-Effective?

The NT$ to JPY exchange rate has surged to 4.85, with an appreciation of 8.7% just this year. As the winter travel season approaches and expectations of the Bank of Japan raising interest rates heat up, more people are looking to exchange for yen. But the real secret to getting a good deal isn’t about “whether to exchange” but “how to exchange.”

We tested the latest rates from five major banks and compiled a comprehensive comparison of four currency exchange methods—helping you spend less and earn more from exchange gains.

Why is it worth exchanging for yen? The dual role of hedging + investment

When it comes to foreign currencies, many people only think of travel. But the yen has long surpassed the “pocket money” role.

Travel and practical use in daily life:
Japanese stores still have a cash usage rate of about 40% (credit card penetration is only 60%), especially in popular tourist spots like Tokyo, Osaka, and Okinawa, where many small shops, restaurants, and convenience stores still rely on cash transactions. Purchasing agents, Japanese online shopping, students working abroad—all need yen payments. This makes yen the most commonly encountered foreign currency among Taiwanese.

Financial market role—one of the world’s three major safe-haven currencies:
The yen, along with the US dollar and Swiss franc, is considered a global safe-haven asset. When the Russia-Ukraine conflict erupted in 2022, the yen appreciated by 8% in a week, while global stock markets fell 10%—demonstrating the power of safe-haven assets. For investors sensitive to Taiwan stock market volatility, holding yen is akin to buying insurance.

Plus, Japan’s economic fundamentals are stable, with relatively healthy debt structure. When global markets are turbulent and capital seeks safety, the yen naturally becomes a target for influx of hot money.

Is now a good time to exchange yen by the end of 2025? Timing analysis

Data review:
At the start of 2025, the NT$ to JPY rate was 4.46. Now it’s 4.85, an appreciation of 8.7%. For Taiwanese investors, this appreciation is quite significant, especially under the continuous depreciation pressure on the NT$.

Recent catalysts:
The Governor of the Bank of Japan, Ueda Kazuo, recently signaled a hawkish stance. The market expects a 0.25 basis point rate hike at the December 19 meeting to 0.75% (a 30-year high). The 10-year Japanese government bond yield has risen to 1.93% (a 17-year high). In contrast, the US Federal Reserve is entering a rate cut cycle, which may gradually narrow the interest rate differential—providing support for the yen.

Short- and medium-term forecasts:

• Short-term (1-3 months): USD/JPY may fluctuate between 154-155
• Medium-term (3-12 months): expected below 150
• Risks: unwinding arbitrage trades (shorting low-interest yen to buy high-interest USD and closing the position) could cause short-term volatility of 2-5%

Investment advice:
It’s worthwhile, but not recommended to exchange all at once. Staggered entry and risk diversification are the right approaches.

Complete comparison of 4 yen exchange methods

Exchanging NT$50,000 via different channels can cost between NT$500 and NT$2000. Below are the tested data and usage suggestions for each method.

Method 1: Bank counter cash exchange—most traditional but highest cost

Operation logic:
Bring cash to a bank branch or airport counter and exchange for yen cash on the spot. This uses the “cash selling rate,” which is about 1-2% worse than the international spot rate.

Latest bank rates (2025/12/10 morning):

(Note: Exchanging NT$50,000 cash at the counter incurs an estimated loss of NT$1500-2000)

Pros: Safe, reliable, denominations available (1000/5000/10000 yen), staff on-site confirmation.

Cons: Exchange rate spread, bank hours (9:00-15:30), some banks charge additional fees.

Suitable for: Those unfamiliar with online operations, urgent airport needs, small amounts (like NT$20,000-30,000).

Method 2: Online currency exchange + foreign currency ATM withdrawal—balance of flexibility and speed

Operation logic:
Use bank app or online banking to convert NT$ to yen and deposit into a foreign currency account. If cash is needed, withdraw via foreign currency ATM or counter. Uses the “spot selling rate,” which is about 1% better than cash selling rate.

Timing tips:
Online exchange can be done 24/7, no banking hours restriction. For cash withdrawal, foreign currency ATMs support 24 hours, but peak times (airports, stations) may run out of cash. It’s recommended to do this 1-3 days in advance to avoid last-minute issues.

Fee breakdown (e.g., E.SUN Bank):

• Online exchange fee: usually free or NT$10-50
• ATM withdrawal fee: NT$5-100 per transaction
• Spread cost (cash rate vs spot rate): NT$100-300

(Note: Exchanging NT$50,000 online + ATM withdrawal costs roughly NT$500-1000)

Pros: Instant withdrawal, 24/7 access, can split into multiple transactions, better exchange rates, low cross-bank fees.

Cons: Need to open a foreign currency account in advance, cash withdrawal limit (~NT$150,000/day), possible cash shortages during peak times.

Suitable for: Those experienced with forex, regularly using foreign currency accounts, wanting to buy yen in installments.

Method 3: Online exchange + airport or branch pickup—best pre-trip reservation plan

Operation logic:
No need to pre-open a foreign currency account. Fill out remittance form online (currency, amount, pickup branch, date). After remitting, bring ID and transaction notice to the designated branch to pick up cash. Taiwan Bank’s “Easy Purchase” and Mega Bank offer this service.

Taiwan Bank “Easy Purchase” highlights:

• About 0.5% better than counter cash selling rate
• NT$10 handling fee (via Taiwan Pay)
• Book at Taoyuan Airport’s 14 locations, 2 of which are 24-hour
• 1-3 days from booking to pickup

(Note: NT$50,000 online exchange + airport pickup costs estimated NT$300-800)

Pros: Better rates, low or no fees, choose airport pickup (most convenient on departure day), no need to open a foreign currency account.

Cons: Must pre-book (no last-minute), pickup only at booked branch, wait during banking hours.

Suitable for: Planned travelers, early arrangements, business travelers or free travelers wanting to pick up yen at the airport.

Method 4: Foreign currency ATM—24-hour emergency rescue

Operation logic:
Use chip-enabled bank card at foreign currency ATMs to withdraw yen cash. Deducts directly from NT$ account, cross-bank fee NT$5, no remittance fee. Limited ATM locations (~200 nationwide), fixed denominations (1000/5000/10000 yen), withdrawal limits apply.

2025 updates:
From October, many banks have strengthened anti-fraud measures. Tier 3 digital accounts now have a daily withdrawal limit of NT$100,000. Traditional accounts remain at NT$120,000-150,000 per day.

Latest limits (2025/12/10):

(Note: Withdrawing NT$50,000 via ATM costs about NT$800-1200 in loss)

Pros: 24/7 instant withdrawal, low cross-bank fee (NT$5), no remittance fee, good for urgent needs.

Cons: Limited locations, fixed denominations, often out of cash during peak times, withdrawal limits require multiple trips.

Suitable for: Time-sensitive, no time to visit bank, last-minute need for yen.
