Entering the end of 2025, the NT dollar to Japanese yen exchange rate reaches 4.85, prompting a rebound in travel demand to Japan and renewed interest in foreign currency allocations.

This article summarizes the latest four major currency exchange options to help you find the most suitable exchange pathway.

Why is it worth exchanging for Japanese yen? A comprehensive analysis from daily life to investment

Daily Consumption: Travel, Shopping, and Learning

Japan remains the top destination for Taiwanese travelers, with high cash demand. Retail stores in Tokyo and Osaka accept cash over 60% of the time. Coupled with purchasing agents, online shopping in Japan, studying abroad, and part-time work scenes, the demand for yen persists. Many people exchange cash before departure to avoid fluctuations at the last minute.

Financial Allocation Perspective: One of the three major safe-haven currencies

Clear Safe-Haven Properties

The Japanese yen has long been ranked among the top three global safe-haven currencies alongside the USD and Swiss franc. During the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a single week, successfully hedging against a 10% decline in global stock markets. For Taiwanese investors, holding yen is not only convenient for travel but also a tool for hedging against Taiwan stock market volatility.

Arbitrage Trading Mechanism

The Bank of Japan maintains ultra-low interest rates (~0.5%), making the yen a preferred currency for global financing. Investors often borrow low-interest yen to buy higher-yield USD assets, with a USD-JPY interest rate differential of about 4.0%. When risks rise, the chain reaction of closing positions and buying back yen further boosts yen demand.

Four Major Ways to Exchange NT Dollars for Yen in Taiwan

Option 1: Bank Counter Direct Exchange

The traditional method: bring NT cash to a bank or airport counter for on-the-spot yen cash exchange. Simple to operate but uses the “cash selling rate,” which is usually 1-2% worse than the spot rate, plus possible handling fees, making it the most costly option. Recommended only for emergencies.

For example, Taiwan Bank’s cash selling rate on December 10, 2025, is 0.2060 (meaning 1 NT dollar = 4.85 yen). Some banks charge fixed handling fees separately.

Bank Cash Selling Rates and Fees (as of 2025/12/10)

Advantages: Safe, full denominations, on-site assistance
Disadvantages: Worse exchange rate, limited operating hours, handling fees apply
Suitable for: Users uncomfortable with online operations or needing small urgent amounts

Option 2: Online Currency Exchange + In-Person Pickup

Use bank app or online banking to convert NT to yen at the “spot sell rate” (about 1% better than cash rate). If cash withdrawal is needed, go to a counter or foreign currency ATM, which incurs additional withdrawal fees (starting from NT$100).

Ideal for investors monitoring exchange trends and entering in installments, e.g., when NT to yen drops below 4.80, to average costs over multiple transactions.

Advantages: 24/7 operation, installment entry, relatively favorable rates
Disadvantages: Need to open a foreign currency account beforehand, withdrawal fees apply
Suitable for: FX experienced investors holding yen long-term, possibly transferring to fixed deposits (interest rate ~1.6%)

Option 3: Online Currency Settlement + Airport Pickup

No foreign currency account needed. Fill in the amount, pick a branch and date online; then pick up with ID at the counter. Taiwan Bank’s “Easy Purchase” offers fee-free service (NT$10 with TaiwanPay), with a 0.5% better exchange rate. Taoyuan Airport has 14 service points, including 2 open 24 hours.

Best for pre-trip planning, allowing direct cash pickup at the airport, saving time from bank visits in the city.

Advantages: Better rates, often fee-free, convenient airport pickup
Disadvantages: Need to book 1-3 days in advance, pickup only during operating hours, branch changes not allowed
Suitable for: Travelers with confirmed itineraries wanting to pick up cash at the airport

Option 4: Foreign Currency ATM Immediate Withdrawal

Use a chip-enabled financial card to withdraw yen at foreign currency ATMs, supporting 24-hour, cross-bank withdrawals (NT$ only NT$5 fee). Yongfeng Bank’s foreign ATM allows withdrawing yen from NT dollar accounts, with a daily limit of NT$150,000 and no currency conversion fee.

Approximately 200 units nationwide, but Japanese ATM services will be adjusted by end of 2025, requiring international cards (Mastercard/Cirrus). During peak times, cash may run out; plan ahead.

Advantages: 24/7 instant withdrawal, low cross-bank fee, high flexibility
Disadvantages: Limited locations, fixed denominations (1,000/5,000/10,000 yen), possible stockouts during peak hours
Suitable for: Urgent needs, last-minute cash requirements

Cost and Situation Comparison of the Four Options

When is the right time to exchange for yen in 2025?

In December 2025, the NT dollar to yen rate is at 4.85, appreciating 8.7% from the start of the year at 4.46. Exchange gains are considerable, especially given NT’s depreciation pressure. The second half of the year saw a 25% growth in foreign exchange demand, mainly from travel recovery and hedging needs.

Short-term Trend Analysis

BOJ Governor Ueda Kazuo recently made hawkish remarks, raising rate hike expectations to 80%. The December 19 meeting is expected to raise rates by 0.25 bps to 0.75% (a 30-year high), with Japanese bond yields hitting 1.93%, the highest in 17 years. The USD/JPY has fallen from a high of 160 at the start of the year to 154.58; short-term fluctuations may touch 155, but long-term forecasts suggest below 150.

Investment Advice

The yen’s safe-haven character is clear, suitable for hedging Taiwan stock market fluctuations. Short-term risks involve arbitrage closing, potentially causing 2-5% volatility. Use phased entry strategies to avoid putting all funds in at once.

Future options for yen allocation

After exchanging yen, don’t idle — consider further allocation to income or growth tools:

Yen Fixed Deposit: Steady choice, E.SUN and Taiwan Bank offer FX accounts with a minimum of 10,000 yen, annual interest around 1.5-1.8%.

Yen Insurance Policies: Medium-term holding, Cathay and Fubon life offer savings insurance with guaranteed rates of 2-3%.

Yen ETFs: Growth-oriented, e.g., Yuanta 00675U tracking yen index, can be bought in broker apps in fractional shares, suitable for dollar-cost averaging.

FX Swing Trading: Advanced option, trade USD/JPY or EUR/JPY directly on FX platforms, supporting long/short positions, 24-hour trading, with modest capital. Offers complete tools, tight spreads, instant signals. Yen’s dual fluctuation, BOJ rate hikes, and global arbitrage or geopolitical risks may affect the trend. Yen ETFs (e.g., 00675U with 0.4% annual management fee) can diversify risk.

FAQ

Q: What’s the difference between cash rate and spot rate?

Q: What do I need to bring for counter exchange?

Taiwanese nationals: ID + passport; foreigners: passport + resident certificate; company: business license. For online booking: transaction notice. Under 20 requires parental accompaniment; amounts over NT$100,000 may require source declaration.

Summary Recommendations

Yen has shifted from a “travel pocket money” role to also serve as a hedge and small investment asset. Whether for overseas spending or asset allocation, applying the principles of “Phased exchange + Activation after full exchange” minimizes costs and maximizes returns.

Newcomers should start with “Taiwan Bank online exchange + airport pickup” or “foreign currency ATM,” then, as needed, move into fixed deposits, ETFs, or experiment with swing trading. This approach not only makes travel more economical but also adds protection amid global market fluctuations.
