Where is the most cost-effective place to exchange TWD to JPY? The ultimate guide to exchanging 50,000 TWD

Latest Market Update December 2025: The TWD to JPY exchange rate has reached 4.85. If you’re planning to exchange for Japanese yen, now is the time to act.

According to the latest statistics, Taiwan’s foreign exchange demand has increased by 25% in the second half of this year. Many are asking the same question—where is the best place to exchange for yen without losing out?

Actually, exchanging for yen is not just about traveling abroad; it involves multiple factors such as exchange rate fluctuations, transaction fees, withdrawal times, and more. Today, we’ll use real numbers to show you how to choose the most cost-effective among Taiwan’s top five yen exchange channels.

Why Now Is a Good Time to Exchange for Yen

This year’s yen has been on an astonishing rise. From 4.46 at the start of the year to 4.85 now, appreciating by 8.7%. What does this mean for Taiwanese investors?

First, travel costs decrease. With NT$50,000, at the beginning of the year, you could only get about 230,000 yen; now, you can get 242,500 yen. This can save a lot on your Japan trip budget.

Second, hedging value emerges. The yen is one of the three major safe-haven currencies globally (alongside USD and Swiss Franc). When global stock markets shake, the yen often rises inversely. During the Russia-Ukraine conflict in 2022, the yen appreciated by 8% in a week, successfully buffering the Taiwan stock index’s 10% decline.

Third, the Bank of Japan is on the verge of raising interest rates. Governor Ueda Kazuo’s recent hawkish comments have pushed market expectations to 80%, with a rate hike to 0.75% expected in December (a 30-year high). The yield on Japanese government bonds has hit a 17-year high of 1.93%, directly increasing the attractiveness of yen investments.

Therefore, exchanging yen now is not just for travel expenses but also a strategic asset allocation choice.

Top 5 Most Used Yen Exchange Channels in Taiwan—Where Is Cheapest?

Exchanging yen may seem simple, but just the method of exchange can cost you NT$200 to NT$2,000 more. Let’s analyze the five most common channels used by Taiwanese people:

First: Bank Counter Cash Exchange (Most Traditional, Not Always Cheapest)

Bring cash NT$ to a bank branch or airport counter and exchange it for yen cash on the spot. This is the old-school method, visible and tangible, but often costly.

Bank counter rates are based on “cash selling rates,” which are about 1-2% worse than the interbank spot rate. For example, Taiwan Bank’s cash selling rate on December 10, 2025, is approximately NT$0.2060 per yen (meaning NT$1 = 4.85 yen).

Calculating NT$50,000:

• Cash selling rate: NT$50,000 ÷ 0.2060 ≈ 242,718 yen
• Plus possible handling fees (some banks charge NT$100-200 per transaction)

Conclusion: Max loss NT$1,500-2,000. Suitable only for urgent airport needs or those unfamiliar with online methods.

Quick reference for bank cash selling rates (2025/12/10):

• Taiwan Bank: 0.2060 NT$/yen (no fee)
• E.SUN Bank: 0.2058 NT$/yen (NT$100 fee)
• Mega Bank: 0.2062 NT$/yen (no fee)
• CTBC Bank: 0.2065 NT$/yen (no fee)
• E.SUN Bank: 0.2067 NT$/yen (NT$100 fee)
• Taipei Fubon Bank: 0.2069 NT$/yen (NT$100 fee)
• Cathay United Bank: 0.2063 NT$/yen (NT$200 fee)

Second: Digital Bank Online Transfer (Suitable for Investors)

Use banking apps or web platforms to transfer NT$ directly into a foreign currency account holding yen. This uses the “spot selling rate,” which is about 1% better than cash selling rates.

But there’s a catch: Yen in a foreign currency account is just a digital balance, not cash. To withdraw physical yen cash, you’ll need to pay another fee (around NT$100-200), plus incur exchange rate spreads.

For example, E.SUN Bank offers low online transfer fees, but withdrawing cash involves paying the “difference between spot and cash rates,” at least NT$100. So, both entering and exiting incur costs.

Conclusion: Loss NT$500-1,000. But if you don’t plan to withdraw cash and just keep yen in the bank for fixed deposits (annual interest 1.5-1.8%), this method can be the most cost-effective.

Use case scenarios:

• ✅ Investing in yen fixed deposits
• ✅ Buying yen ETFs (e.g., Yuanta 00675U)
• ✅ Forex traders
• ❌ Need cash for Japan travel

Third: Online Currency Exchange + Airport Pickup (Most Popular for Office Workers)

Taiwan Bank and Mega Bank offer this service: fill out an online form (currency, amount, pickup date, branch), and the bank pre-converts to yen. You then pick up cash at the airport branch the day before or on the day of travel.

Main advantage: Taiwan Bank’s “Easy Purchase” online exchange is completely fee-free (using Taiwan Pay costs NT$10), with about 0.5% better rates. Taoyuan Airport has 14 Taiwan Bank counters, 2 of which are open 24 hours.

For NT$50,000, the loss is only NT$300-800, making it the most cost-effective cash method currently.

Disadvantages: Requires advance booking (1-3 days), pickup only during bank hours (usually 9:00-20:00), and the selected branch cannot be changed on short notice.

Conclusion: Cheapest cash method, with a loss of NT$300-800.

Fourth: Foreign Currency ATM Withdrawal (Most Flexible)

Bring a chip-enabled bank card to a foreign currency ATM, and withdraw yen cash 24/7. Interbank withdrawals cost NT$5 per transaction, no exchange fee. Some ATMs (e.g., E.SUN) have a daily limit of NT$150,000 equivalent yen.

Advantages: Instant, flexible, low fees. Ideal for sudden yen needs.

Disadvantages: Only about 200 ATMs nationwide (limited locations), fixed denominations (1,000, 5,000, 10,000 yen), and during peak times (like airports), cash may run out. By the end of 2025, Japanese ATMs will require international cards (Mastercard/Cirrus).

Conclusion: Loss NT$800-1,200 but very convenient.

Fifth: On-site Currency Exchange Booths (Common at Airports, Most Expensive)

Some travelers see dedicated currency exchange counters at airports, but rates are usually worse, with higher fees. Unless in urgent need, this method is not recommended.

How to Decide if Now Is a Good Time to Exchange Yen

Many ask: “Should I exchange in December 2025?”

Answer: Yes, but do it in installments.

Currently, USD/JPY fluctuates around 154.58, with significant volatility. Short-term, it may rebound to 155, but medium to long-term, it is expected to stay below 150. To avoid the risk of exchanging all at once and catching a bad rate, we suggest:

1. First batch (immediately): Exchange 50-70% needed for travel, locking in costs.
2. Second batch (within a week): Observe the rate; add more when NT$ to JPY drops below 4.80.
3. Third batch (for investment): If for hedging assets, gradually exchange over 3-6 months.

This way, you ensure you have yen for use and diversify exchange risk.

After Exchanging Yen, Don’t Just Leave It Idle

Getting yen is just the first step; how you use it matters.

Option 1: Yen Fixed Deposit (Stable)
Open a foreign currency account and deposit yen. E.SUN and Taiwan Bank offer annual interest rates of 1.5-1.8%, starting from 10,000 yen. For 100,000 yen, annual interest is about 1,500-1,800 yen.

Option 2: Yen Insurance Policy (Mid-term)
Cathay and Fubon offer yen savings insurance with guaranteed rates of 2-3%, suitable for 3-10 year allocations.

Option 3: Yen ETFs (Growth)
Yuanta 00675U tracks the yen index, available via brokerage apps. Management fee only 0.4% annually, suitable for regular investment.

Option 4: Forex Swing Trading (Advanced)
Trade USD/JPY or EUR/JPY directly, leveraging rate fluctuations. 24/7 trading, can go long or short, but higher risk—suitable for experienced traders.

Conclusion: Choose based on your timeline and risk appetite. Don’t just exchange and leave it; let yen work for you.

Summary

2. Keep working: After exchange, use fixed deposits, ETFs, or forex trading to let yen continue working for you.

Beginners should start with the simplest options—“Taiwan Bank online exchange + airport pickup” or “foreign currency ATM”—then expand into fixed deposits, ETFs, or swing trading based on needs. This way, you can enjoy more cost-effective trips and better protection during market volatility.
