How to exchange Japanese Yen without losing out? A comparison of 4 major exchange channels in practical tests

The NT$ to JPY has appreciated by 8.7% this year. Is now a good time to exchange for Japanese Yen?

By the end of 2025, the NT$ to JPY exchange rate is projected to reach 4.85, prompting many to prepare for currency exchange. But the issue is—exchanging NT$50,000 into JPY through the wrong channel could cost you an extra NT$1,500. We tested the four most common methods in Taiwan to show you which is the most cost-effective.

Is it really worth exchanging for JPY?

When it comes to foreign currency investment, many first think it’s only necessary when traveling abroad. But the uses for JPY go far beyond that.

Daily applications: Japan mainly accepts cash (credit card penetration is only 60%), so purchasing Japanese cosmetics, fashion, or anime merchandise requires paying directly in Yen. Even students planning to study or work in Japan need to exchange money in advance.

Financial investment: The Yen is one of the world’s three major safe-haven currencies (along with USD and CHF). During market turbulence, funds flow into Yen—during the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a week, successfully hedging stock market declines. For Taiwanese investors, this adds a layer of protection when Taiwan stocks are volatile.

Additionally, the Bank of Japan (BOJ) has recently shifted to a more hawkish stance. Governor Ueda hinted at an imminent rate hike, with market expectations of a 0.25 percentage point increase to 0.75% on December 19 (a 30-year high), and Japanese government bond yields have surged to 1.93%. These signals indicate: it’s not too late to pay attention to the Yen now.

Four channels to exchange NT$ for JPY, with vastly different costs

Many think exchanging Yen is just going to the bank counter for cash, but in reality, handling fees and exchange rate spreads can cost you several cups of bubble tea. Based on the latest December 2025 rates, we’ve calculated the costs for each method clearly.

Method 1: Bank counter exchange (most traditional, highest cost)

Bring NT$ cash directly to a bank or airport counter to buy JPY cash. It seems simple but is actually the most costly—because banks use the “cash selling rate,” which is 1-2% worse than the market spot rate, plus handling fees, costing NT$1,500-2,000 (for NT$50,000).

Taiwan Bank’s cash selling rate is about 0.2060 NT$/JPY (1 NT$ ≈ 4.85 JPY), and E.SUN Bank charges an additional NT$100 per transaction. This method is only suitable for urgent airport needs or small amounts.

Method 2: Online currency exchange + in-person pickup (balanced, moderate cost)

Use a bank app to convert NT$ into JPY and deposit into a foreign currency account, using the “spot sell rate” (about 1% better than cash rate). If you want cash, pick it up at the counter or ATM, which incurs extra handling fees (minimum NT$100).

Ideal for those observing exchange rate trends and buying in installments. For example, only exchange when NT$ to JPY drops below 4.80 to average costs. Cost is about NT$500-1,000, saving half compared to the first method.

Method 3: Online currency conversion, then pick up at airport or designated branches (most recommended, lowest cost)

No need to open a foreign currency account. Just fill in currency, amount, and pickup location on the bank’s website, then bring ID and transaction notice to pick up in person. Taiwan Bank’s “Easy Purchase” online currency exchange is fee-free (using Taiwan Pay costs only NT$10), with about 0.5% better rates.

The best part— you can pre-book and pick up at 14 Taiwan Bank locations at Taoyuan Airport, including 2 open 24 hours. No need to rush to the bank before your trip; just book online from home. Cost is NT$300-800, making it the most cost-effective.

Method 4: Foreign currency ATM withdrawal (most flexible, 24/7)

Use a chip-enabled debit card at a foreign currency ATM to withdraw Yen directly, available 24 hours. E.SUN Bank’s foreign currency ATMs allow NT$ withdrawal limits of NT$150,000 per day, with no currency exchange fee, and only NT$5 for interbank transactions.

The downside: limited locations (about 200 nationwide), and currency denominations are restricted (usually only 1,000, 5,000, 10,000 Yen). During peak times, cash may run out, so don’t wait until the last minute. Cost is NT$800-1,200, mid-range.

Cost comparison table (for exchanging NT$50,000):

Is it really advantageous to exchange Yen now? What should you watch out for?

Answer: Yes, it’s advantageous—but operate in installments.

By the end of this year, NT$ to JPY has appreciated to 4.85, up 8.7% from the start of the year’s 4.46, making the investment gains quite substantial. Especially under the backdrop of NT$ depreciation pressure, exchanging for Yen acts as a form of hedging.

But don’t convert everything at once. The Yen exchange rate is still quite volatile—an interest rate cut cycle in the US favors Yen, but global arbitrage unwinding or geopolitical risks in Taiwan and the Middle East could push it down. USD/JPY has fallen from 160 at the start of the year to 154.58, with short-term fluctuations around 155, but medium to long-term forecasts are below 150.

Strategy suggestion: Make 3-4 smaller exchanges instead of all at once. This way, you can catch lows and hedge against highs.

After exchanging for Yen, don’t let your money sit idle

Once you’ve exchanged Yen, the biggest mistake is “leaving it idle.” There are several options now, and beginners can start simple:

1. Yen fixed deposit (safe and steady) Open a foreign currency account at E.SUN or Taiwan Bank, deposit Yen into a fixed deposit. Minimum NT$10,000 equivalent, annual interest rate 1.5-1.8%. It’s like letting Yen sit and earn interest.

2. Yen insurance policy (medium-term growth) Buy Yen-denominated savings insurance from Cathay or Fubon Life, with guaranteed interest rates of 2-3%, plus risk management.

3. Yen ETFs (growth-oriented) For example, Yuanta 00675U tracks Yen index, can be bought as fractional shares via brokerage apps, suitable for dollar-cost averaging. Management fee only 0.4%, suitable for both bullish and bearish strategies.

4. Forex trading (short-term gains) Trade USD/JPY or EUR/JPY directly on platforms like Mitrade. Both long and short positions, 24/7 operation, zero commissions, low spreads—ideal for capturing short-term volatility.

Common Q&A

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

Cash rate is the rate banks offer for physical cash transactions, paid immediately but costly. Spot rate is the foreign exchange market’s T+2 settlement rate, closer to international market prices but requires waiting for settlement. In short: cash is quick but expensive; spot is cheaper but takes time.

Q: How much Yen can NT$10,000 buy?

Using the Taiwan Bank cash rate of 4.85, NT$10,000 ≈ 48,500 Yen. Using the spot rate (~4.87), it’s about 48,700 Yen—difference of 200 Yen (roughly NT$40).

Q: What documents are needed to exchange foreign currency?

For in-person at the counter, bring ID + passport (foreigners bring passport + residence permit). For online booking, also need transaction notice. Under 20 years old requires a parent’s presence. Large amounts over NT$100,000 may require source of funds declaration.

Q: Are there withdrawal limits at foreign currency ATMs?

Yes. CTBC Bank’s card limit is equivalent to NT$120,000 per day; E.SUN and Yuanta are NT$150,000. After 2025, most banks lowered daily limits to NT$100,000-150,000. It’s advisable to split withdrawals to avoid hitting limits.

Final advice on exchanging Yen

Yen is no longer just pocket money for travel; it has hedging and investment value. Whether you’re planning a trip to Japan next year or want to hedge against NT$ depreciation, the key is “staged exchange + shifting into income-generating tools.”

Beginners can simply choose “Taiwan Bank online currency exchange” or “foreign currency ATM,” then transfer Yen into fixed deposits, ETFs, or forex trading based on needs. This way, you can enjoy more cost-effective trips and add a layer of protection amid global market turbulence.
