2025 Yen Exchange Guide: Cost Comparison of 4 Methods, Is Online Currency Exchange Actually the Cheapest?

December 10, 2025, the exchange rate of New Taiwan Dollar to Japanese Yen reaches 4.85, an 8.7% appreciation since the beginning of the year. Want to exchange for Yen but overwhelmed by various fees? We tested the four most common exchange channels in Taiwan and used real data to tell you which combination is the most cost-effective.

Is now really a good time to exchange for Yen?

Brief answer: Yes, but with conditions.

The Yen has appreciated 8.7% this year. Market expectations suggest the Bank of Japan will raise interest rates to a 30-year high of 0.75% on December 19. Japanese government bond yields have hit a 17-year high of 1.93%. Meanwhile, the US is entering a rate-cut cycle, and arbitrage trades may face unwinding pressure, with short-term volatility estimated at 2-5%. USD/JPY has fallen from 160 at the start of the year to 154.58; medium-term outlook is below 150.

For Taiwanese investors, the Yen serves both travel needs and hedging properties. But don’t exchange all at once; staggered entry is the best strategy.

Four Yen exchange methods with significant cost differences

Taking NT$50,000 as an example, actual expenses can differ by over NT$1,000 depending on the channel. Here’s a breakdown:

Method 1: Bank Counter (most traditional and most expensive)

Walk into a bank branch or airport counter and exchange NT$ cash for Yen notes on-site. The simplest operation, but uses the “cash selling rate,” usually 1-2% worse than the spot rate, plus possible fees, making it the most costly.

Real data (December 10, 2025):

• Taiwan Bank: cash selling rate 0.2060 (no fee)
• E.SUN Bank: cash selling rate 0.2058 (NT$100 per transaction)
• Taipei Fubon: cash selling rate 0.2069 (NT$100 per transaction)

Exchanging NT$50,000 results in a loss of NT$1,500-2,000.

Suitable for: Urgent needs (e.g., airport cash shortage), unfamiliar with online methods.

Method 2: Foreign Currency ATM Withdrawal (24/7 convenience, limited)

Use a chip-enabled bank card at foreign currency ATMs to withdraw Yen, supporting interbank transactions with only NT$5 fee, about 200 locations nationwide. Flexible withdrawal limits (E.SUN up to NT$150,000 daily), instant cash.

Disadvantages: limited locations, fixed denominations (1,000/5,000/10,000 Yen), often out of stock during peak times. Japan ATM services will be adjusted by end of 2025, requiring international cards.

Estimated cost: NT$800-1,200 loss (including interbank fees and exchange margin)

Suitable for: No time to visit bank, need immediate cash, 24/7 emergency.

Method 3: Online FX + Counter Pickup (better rates, transparent fees)

Use bank app or website to convert NT$ to Yen at “spot selling rate,” deposit into foreign currency account, then choose counter or ATM pickup. Online exchange fees are usually lower (e.g., E.SUN charges NT$100+), with about 1% better rates.

Requires opening a foreign currency account, which is also the foundation for long-term Yen investments. Can stagger purchases at low points (e.g., when NT$ to Yen drops below 4.80) to average costs.

Estimated cost: NT$500-1,000 loss

Suitable for: Experienced forex investors, long-term Yen holdings, planning Yen deposits (annual interest 1.5-1.8%).

Method 4: Online FX + Airport Pickup (most recommended for travel)

No need for a foreign currency account. Select currency, amount, designated airport branch, and pickup date on the bank’s website. After completion, bring ID and transaction notification to pick up in person. Taiwan Bank’s “Easy Purchase” online FX has no fee (pay NT$10 via TaiwanPay), with a 0.5% rate advantage.

Ideal for pre-trip planning, especially Taoyuan Airport has 14 Taiwan Bank branches (2 open 24 hours). Must book 1-3 days in advance; pickup during bank hours.

Estimated cost: NT$300-800 loss

Suitable for: Planned travelers, pre-departure arrangements, direct airport cash pickup.

Comparison table of the 4 methods

Conclusion: For travel, online FX + airport pickup is the most cost-effective; for investment, online FX + deposit is second; for urgent needs, consider counters or ATMs.

After getting Yen, don’t let it sit idle

Exchanging Yen is not the end. Depending on your purpose, you can shift to steady income or growth assets:

1. Yen Fixed Deposit (stable, annual interest 1.5-1.8%)
E.SUN, Taiwan Bank foreign currency accounts, starting from 10,000 Yen, using interest to buffer exchange losses.

2. Yen Insurance Policies (medium-term holding, guaranteed interest 2-3%)
Cathay, Fubon life savings insurance, locking in longer-term returns.

3. Yen ETFs (growth-oriented, management fee 0.4% annually)
Like Yuanta 00675U tracking Yen index, fractional share dollar-cost averaging to diversify volatility.

4. Forex Swing Trading (two-way opportunities)
Trade USD/JPY, EUR/JPY on forex platforms to capture short- to medium-term fluctuations, suitable for experienced investors.

Though Yen is a hedge currency, it exhibits two-way volatility. Global arbitrage unwinding or geopolitical risks may temporarily depress it. Long-term outlook is positive but requires diversification.

Final advice for exchanging Yen

Yen has evolved from a travel “pocket money” to an asset with hedging and investment value. With an 8.7% appreciation in 2025, the gains can be significant, especially as the NT$ faces depreciation pressure.

Two core principles: Staggered exchange + don’t leave funds idle after exchange.

Beginners are advised to start with “Taiwan Bank online FX + airport pickup” or “foreign currency ATM” to acquire cash at minimal cost. After obtaining Yen, adjust your strategy based on risk appetite—deposit, ETFs, or swing trading—to keep your capital working.

This approach reduces exchange costs and adds a layer of protection against global market shocks, making your travel more economical and your investments smarter.
