Yen Exchange Strategy: Cost Comparison of 4 Major Channels, Is Now the Right Time to Enter?

Recent pressures on the TWD depreciation have intensified, and the Japanese Yen, as one of the three major safe-haven currencies, has attracted increasing investor attention. As of December 2025, the TWD/JPY exchange rate has risen above 4.85, up 8.7% from 4.46 at the beginning of the year, offering considerable exchange gains. However, to minimize currency exchange costs, you need to understand the differences behind four channels—since just choosing the exchange rate can cost you several thousand TWD more.

JPY, GBP, USD: Taiwan’s Top Three Favorite Foreign Currencies

When it comes to currency exchange, Taiwanese people usually think of the Yen first. But in reality, GBP and USD are also popular options. Many compare “how many TWD for 1 GBP” and “how many TWD for 1 USD” to decide investment allocations, but the Yen has a unique advantage—it meets travel needs and also has financial attributes.

Why is it worth exchanging to Yen?

Travel Expenses and Daily Life
Japan’s cash culture is deeply ingrained; most merchants only accept cash (credit card penetration is about 60%). Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, you need cash in Yen. Additionally, Japan shopping agents, anime merchandise, and drugstore enthusiasts often pay directly in Yen.

Safe-Haven Asset Attribute
The Yen ranks among the world’s three major safe-haven currencies (alongside USD and Swiss Franc) due to Japan’s stable economy and low government debt. During market turbulence, funds flow into Yen to preserve value. During the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a week, effectively buffering a 10% decline in the stock market. For Taiwanese investors, Yen becomes a tool to hedge against Taiwan stock risks.

Interest Rate Arbitrage Opportunities
Japan maintains ultra-low interest rates (only 0.5%), making Yen a “funding currency.” Many investors borrow Yen at low interest, convert to higher-yield USD, and enjoy a 4.0% interest rate differential. When risks increase, they close arbitrage trades, causing Yen prices to fluctuate.

Exchange Rate Trend Analysis

Currently, Yen is in an upward trend. After the US entered a rate-cut cycle, Yen gained support; the Bank of Japan is on the verge of raising rates—Governor Ueda’s hawkish comments pushed the rate hike expectation to 80%, with a 0.25 basis point increase to 0.75% expected at the December 19 meeting (a 30-year high). The 10-year Japanese government bond yield has hit a 17-year high of 1.93%.

USD/JPY has fallen from a high of 160 at the start of the year to around 154.58 now, with short-term support possibly testing 155, but medium to long-term forecasts are below 150. In other words, now is a good entry point for Yen with both safe-haven value and short-term volatility risk.

Investment Recommendations

• Travel use: Exchanging now is at a relatively high level, but travel timing is critical. Use “online currency exchange + airport withdrawal” to lock in rates.
• Investment allocation: Yen arbitrage risks appear at closing; expect 2-5% volatility. It’s advisable to buy in batches rather than all at once.
• Hedging needs: Gradually purchase foreign currency accounts or Yen fixed deposits for long-term stable returns.

Four Major Channels for Taiwan Yen Exchange Comparison

Many think exchanging Yen only involves going to the bank, but differences in exchange rates and handling fees can cause cost differences of thousands of TWD.

Option 1: Bank Counter Cash Exchange—Most traditional but most expensive

Bring cash TWD to a bank branch or airport counter to exchange for Yen cash. Simple operation, but using “cash selling rate” (1-2% worse than spot rate), results in higher costs.

Actual Example
Using Taiwan Bank’s rate on December 10, 2025, the cash selling rate is 0.2060 TWD/JPY (about 4.85 Yen per TWD). For 50,000 TWD, the loss is about 1,500-2,000 TWD.

Pros & Cons

• Pros: Safe, full denominations, staff assistance
• Cons: Rate spread, limited business hours (Mon-Fri 9:00-15:30)
• Suitable for: Those unfamiliar with online operations or needing small, urgent exchanges

Option 2: Online Currency Exchange + Foreign Currency Account—Moderate cost, suitable for investment

Use online banking or app to convert TWD into Yen and deposit into a foreign currency account, with “spot sell rate” (about 1% better than cash rate). If cash is needed, withdraw at counters or ATMs, but with withdrawal fees (around 100 TWD).

This method suits those monitoring exchange rates, buying in batches at low points (e.g., below 4.80). For 50,000 TWD, loss is about 500-1,000 TWD.

Pros & Cons

• Pros: 24/7 operation, averaging costs, better rates, can switch to Yen fixed deposit (annual interest 1.5-1.8%)
• Cons: Need to open a foreign currency account, withdrawal fees (interbank 5-100 TWD)
• Suitable for: Experienced forex investors, long-term holders

Option 3: Online Currency Exchange + Designated Pickup—Most hassle-free pre-departure plan

No need for a foreign currency account. Fill in currency, amount, pickup branch, and date on the bank’s website. After remittance, bring ID and transaction notice to pick up in person. Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (pay with Taiwan Pay, only 10 TWD), with about 0.5% rate advantage.

Ideal for airport pickup reservations. Taoyuan Airport has 14 Taiwan Bank counters (2 open 24 hours). For 50,000 TWD, loss is about 300-800 TWD.

Pros & Cons

• Pros: Better rates, often no fees, can choose airport branch
• Cons: Need prior reservation (1-3 days), pickup during bank hours
• Suitable for: Planned travelers who arrange ahead

Option 4: Foreign Currency ATM Withdrawal—24/7 flexibility, suitable for urgent needs

Use chip-enabled bank cards at foreign currency ATMs to withdraw Yen cash, supporting 24-hour operation and interbank withdrawals (from TWD account, only 5 TWD fee). For 50,000 TWD, loss is about 800-1,200 TWD.

Different banks have different limits. E.SUN’s foreign currency ATM allows withdrawal of Yen equivalent to TWD 150,000 per day without exchange fee; E.SUN Bank’s own card allows 50,000 TWD (per transaction) or 150,000 TWD (per day).

Note: Japan ATM withdrawal services will be adjusted by end of 2025, requiring international cards (Mastercard/Cirrus).

Pros & Cons

• Pros: Instant withdrawal, high flexibility, low cross-bank fees
• Cons: Limited locations (~200 nationwide), fixed denominations (1,000/5,000/10,000 Yen), cash may run out during peak times
• Suitable for: Those with no time to visit banks or needing immediate cash

Q: What to bring for counter exchange?
Taiwanese: ID + passport; foreigners: passport + residence permit. If pre-booked, also bring transaction notice. Under 20 years old need parent’s consent; large amounts (>100,000 TWD) may require source declaration.
