2025 Yen Exchange Complete Guide: Cost Comparison of 4 Major Channels and the Best Timing

Yen Becomes Taiwan’s New Favorite in Forex Investment

Recently, the TWD/JPY exchange rate broke through 4.85, reigniting travel interest to Japan. However, many may not realize that exchanging yen has long surpassed the simple level of “travel pocket money.”

Unlike other Asian currencies (such as VND, which are mainly used for short- to medium-term hedging), the yen is one of the world’s three major safe-haven currencies, combining both risk-avoidance properties and investment value. Whether planning a trip to Japan, making purchases on behalf of others, or seeking to hedge Taiwan stock market risks through forex allocation, timing and channel choices can significantly reduce costs.

Is it Worth Exchanging Yen? Investment Perspective Analysis

Core Value of Safe-Haven Currencies

The yen, along with the US dollar and Swiss franc, ranks among the top three global safe-haven assets. During the Russia-Ukraine conflict in 2022, the yen appreciated by up to 8% in a single week, effectively buffering stock market declines. For Taiwanese investors, holding yen can serve as a hedge within stock portfolios, especially under ongoing TWD depreciation pressures.

Interest Rate Arbitrage Opportunities

Japan maintains ultra-low interest rates (0.5%), yet creates arbitrage trading space. The US-Japan interest rate differential reaches 4.0%, attracting substantial capital borrowing low-interest yen to invest in higher-yield USD assets. When risk environments shift and these arbitrage trades are closed, the yen often receives support.

Current Exchange Rate Evaluation

As of December 2025, the TWD/JPY rate is about 4.85, up approximately 8.7% from 4.46 at the start of the year. The Bank of Japan (BOJ) Governor Ueda Kazuo recently expressed hawkish views, with market expectations that the December 19 meeting will raise rates to 0.75% (a 30-year high). Japanese government bond yields have hit a 17-year high of 1.93%. USD/JPY has fallen from 160 to around 154.58; medium- to long-term forecasts suggest it will stay below 150, but short-term fluctuations of 2-5% are possible.

Conclusion: Exchanging Yen Now Is Cost-Effective, But Should Be Done in Batches

The exchange rate has reached a relatively favorable level, but short-term volatility exists. It is recommended to exchange in batches based on travel schedules or investment plans to average costs and avoid risks associated with a single large exchange point.

Four Practical Channels for Taiwan Yen Exchange Comparison

Channel 1: Bank Counter Cash Exchange — The Traditional but Most Expensive

Carry TWD cash to a bank or airport counter to exchange for yen cash.

Cost Components: Using cash selling rate (about 98-99% of spot rate), plus bank handling fees (100-200 TWD).

For example, Taiwan Bank as of December 10, 2025, offers a cash selling rate of about 0.2060 TWD/JPY (i.e., 1 TWD = 4.85 JPY). Exchanging 50,000 TWD results in a loss of about 1,500-2,000 TWD.

Advantages: Simple operation, on-site assistance, full denominations (1,000/5,000/10,000 JPY options).

Disadvantages: Larger exchange rate spread, limited by bank hours (9:00-15:30 on weekdays), possible additional fees.

Suitable for: Urgent, small amounts, unfamiliar with online procedures, or travelers with immediate needs.

Channel 2: Online Forex Conversion into Foreign Currency Account — Flexible and Batchable

Use bank app or online banking to convert TWD into JPY and deposit into a foreign currency account (using spot sell rate). If cash is needed, go to counter or foreign currency ATM for withdrawal.

Disadvantages: Need to open a foreign currency account first, withdrawal fees apply.

Investment Extension: After conversion, funds can be placed into fixed deposits (annual interest 1.5-1.8%) or invested in JPY ETFs (e.g., Yuanta 00675U).

Suitable for: Experienced forex traders, long-term holders of yen, seeking interest income.

Channel 3: Online Reservation for Currency Exchange, Pick Up at Airport — The Best Pre-Travel Option

No need for a foreign currency account. Fill in exchange amount, branch, and date on bank website. After online transfer, bring ID and transaction notice to designated branch for pickup.

Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (pay only 10 TWD via TaiwanPay), with a rate advantage of 0.5%. Taoyuan Airport has 14 Taiwan Bank outlets, 2 of which operate 24 hours, offering great convenience.

Cost Components: Favorable rates, often no or very low handling fees. For 50,000 TWD, estimated loss is only 300-800 TWD.

Channel 4: Foreign Currency ATM — 24/7 Instant Withdrawal

Services provided by banks like E.SUN Bank, with daily withdrawal limit around 150,000 TWD (equivalent). Note that Japanese ATMs will be adjusted by end of 2025; for Japanese withdrawals, international cards (Mastercard/Cirrus) are required.

Cost Components: Very low interbank withdrawal fee (5 TWD), no forex exchange fee, but subject to ATM exchange rate margins. For 50,000 TWD, estimated loss is 800-1,200 TWD.

Advantages: Instant 24/7 withdrawal, high flexibility, low interbank fees, no prior reservation needed.

Disadvantages: Limited to about 200 ATMs nationwide, fixed denominations (1,000/5,000/10,000 JPY), cash may run out during peak times (e.g., airports).

Suitable for: Urgent, last-minute travelers needing cash, but not recommended to wait until the last minute.
