JPY Exchange Strategy: Comparing the Costs of 4 Major Channels, How Do I Save the Most?

Why Exchange Yen Now? Dual Benefits of Investment + Travel

When it comes to exchanging yen, many people only think of traveling to Japan, but in fact, the value of the yen goes far beyond that.

Travel Expenses: Shopping in Tokyo, skiing in Hokkaido, vacationing in Okinawa—these places mainly use cash, with only about 60% credit card penetration. When buying cosmetics, clothing, or anime merchandise, you need to pay directly in yen. Even for those planning to study or work abroad, they usually exchange currency in advance to avoid exchange rate fluctuations.

Financial Market Perspective: Yen is no simple currency. It has long been one of the world’s three major safe-haven currencies (alongside USD and Swiss Franc). During market turbulence, funds flow into safe assets—during the 2022 Russia-Ukraine conflict, the yen appreciated 8% in a week, buffering stock market declines. For Taiwanese investors, exchanging yen can hedge against Taiwan stock risks. Plus, Japan’s long-term ultra-low interest rate (just 0.5%) has led many to borrow low-interest yen to invest in higher-yield USD (USD/JPY interest rate differential of 4.0%), creating arbitrage opportunities.

As of December 10, 2025, the TWD/JPY exchange rate is about 4.85, meaning 1 TWD exchanges for 4.85 yen. Compared to the start of the year at 4.46, this is an approximately 8.7% appreciation, making investment gains quite substantial.

4 Ways to Exchange Yen, Cost Differences Are Surprising

Many think that exchanging at the bank counter is the cheapest, but just the exchange rate difference can buy several drinks’ worth of savings. Let’s look at real market prices.

Option A: Cash Exchange at Bank Counter — Most Traditional but Most Expensive

Bring cash TWD directly to a bank or airport counter to exchange for yen cash on the spot. The operation is simple, but it uses the “cash selling rate,” which is about 1-2% worse than the spot rate.

Using Taiwan Bank’s December 10, 2025, rate as an example, the cash selling rate is approximately 0.2060 TWD/JPY (1 TWD = 4.85 JPY). Some banks also charge additional handling fees.

Suitable for: Inexperienced online users, small urgent exchanges (e.g., at the airport).
Estimated Cost: Exchanging 50,000 TWD results in a loss of about 1,500–2,000 TWD.

Option B: Online Transfer & Exchange — Preferred by Investors

Use bank app or online banking to convert TWD to yen at the “spot sell rate” (about 1% discount), then deposit into a foreign currency account. If you want cash, withdraw via foreign currency ATM, paying only withdrawal fees.

Advantages include 24-hour operation and the ability to average costs through multiple entries. E.SUN Bank offers this service, with a minimum deposit of 10,000 yen and an annual interest rate of 1.5–1.8%.

Suitable for: Those experienced with forex, wanting to invest in yen deposits or ETFs.
Estimated Cost: Exchanging 50,000 TWD results in a loss of about 500–1,000 TWD.

Option C: Online Pre-Order & Currency Exchange — Best Planning Before Travel

No need for a foreign currency account. Fill in amount, pick-up branch, and date on the bank’s website. After completing the transfer online, bring ID and transaction notice to pick up in person. Taiwan Bank’s “Easy Purchase” and Mega Bank offer this, with options to pre-arrange airport branch pickup.

Taiwan Bank even waives handling fees (pay only 10 TWD via TaiwanPay), with about 0.5% favorable exchange rate. Taoyuan Airport has 14 Taiwan Bank counters, including 2 open 24 hours.

Suitable for: Planned travelers who want to pick up cash directly at the airport.
Estimated Cost: Exchanging 50,000 TWD results in a loss of about 300–800 TWD.

Option D: Foreign Currency ATM Withdrawal — Emergency Savior

Use a chip-enabled bank card to withdraw yen at foreign currency ATMs, available 24/7. Only 5 TWD cross-bank fee from your TWD account. E.SUN Bank’s foreign currency ATMs have a daily withdrawal limit of 150,000 TWD, with no currency exchange fee.

Key advantage: Many nearby ATMs for instant cash. Especially around airports and train stations, where ATMs are densely located. No need to wait for bank hours. There are about 200 foreign currency ATMs nationwide, with fixed denominations of 1,000/5,000/10,000 yen.

Note: Japan ATM withdrawal services will be adjusted by end of 2025, requiring international cards (Mastercard/Cirrus). During peak times, cash may run out at ATMs, so plan ahead.

Suitable for: Those who don’t have time to visit banks or need urgent cash.
Estimated Cost: Exchanging 50,000 TWD results in a loss of about 800–1,200 TWD.

Is It Worth Exchanging Yen Now? Staggered Strategy Is Most Stable

As of December 2025, TWD/JPY is about 4.85. In the second half of the year, Taiwan’s forex demand grew by 25%, mainly driven by travel recovery and hedging needs.

The yen remains volatile. The US entering a rate cut cycle favors the yen, but the Bank of Japan is on the verge of raising rates—Governor Ueda’s hawkish comments have pushed market expectations of hikes to 80%, with a December 19 meeting expected to raise rates to 0.75% (a 30-year high). USD/JPY has fallen from a high of 160 at the start of the year to 154.58 now; short-term may rebound to 155, but medium to long-term forecasts are below 150.

Conclusion: It’s advantageous to exchange now, but do so in stages. Yen as a safe-haven currency is suitable for hedging Taiwan stocks, but short-term risks include arbitrage unwinding, which could cause 2-5% fluctuations. Stagger your entries to minimize costs.

After Exchanging Yen — Capital Appreciation Strategies

If you just hold the yen without interest, it’s a waste. Here are four options suitable for small-scale beginners:

Yen Fixed Deposit (Conservative): E.SUN/Taiwan Bank foreign currency accounts, online deposit, minimum 10,000 yen, annual interest 1.5–1.8%.

Yen Insurance Policy (Mid-term Hold): Cathay/Fubon life savings insurance, with guaranteed 2–3% interest.

Yen ETFs (Growth): For example, Yuanta 00675U tracking yen index, can buy fractional shares via broker apps, suitable for dollar-cost averaging.

Yen Forex Trading (Swing Trading): Directly trade USD/JPY or EUR/JPY, 24/7 trading, both long and short, low capital threshold, suitable for capturing exchange rate swings.

While yen is a safe haven, it also fluctuates bidirectionally. BOJ rate hikes are positive, but global arbitrage unwinding or geopolitical conflicts may suppress the yen. For investment purposes, yen ETFs with 0.4% annual management fee can diversify risk.

Summary

Yen is no longer just travel “pocket money”—it’s an asset with hedging and investment value. Whether traveling abroad or managing funds, follow the principles of “staggered exchange + don’t just hold after exchanging” to minimize costs and maximize returns.

Beginners are advised to start with “Taiwan Bank online exchange + airport pickup” or “foreign currency ATM,” then transfer yen into deposits, ETFs, or forex swing trades based on needs. This way, you can enjoy cost-effective travel and add a layer of protection during global market turbulence.
