Japanese Yen exchange cost revealed: At the critical moment of NT$ to JPY 4.85, choosing the right method saves thousands of dollars

As the Taiwanese dollar to Japanese yen has reached 4.85 today (December 10, 2025), more and more people are starting to seriously consider the timing of exchanging for yen. But did you know? Exchanging the same 50,000 TWD into yen using different methods can result in a difference of over 1,500 TWD. This is not just a simple choice; it directly affects your wallet’s depth.

Why is it worth exchanging for yen? Not just for traveling abroad

When it comes to currency exchange, many automatically think of yen, but there are deeper reasons behind it.

Essential in daily life scenarios

Traveling in Japan still relies heavily on cash (credit card penetration only 60%), whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, currency exchange is a must. Buyers, anime fans, beauty enthusiasts all need yen for transactions and settlements over the long term. For students planning to study or work in Japan, early planning of currency exchange can effectively avoid additional costs caused by sudden exchange rate fluctuations.

Hedging value of financial assets

The yen is one of the world’s three major safe-haven currencies, alongside the US dollar and Swiss franc, supported by Japan’s stable economy and low government debt. During the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a week, effectively buffering a 10% decline in the stock market—an excellent case for Taiwanese investors using yen to hedge Taiwan stocks.

Additionally, Japan maintains an ultra-low interest rate (only 0.5%), giving it a special status as an “arbitrage currency.” Many institutional investors borrow low-interest yen, convert to higher-yield USD investments (the USD/JPY interest rate gap reaching 4.0%), and when risks increase, close positions to buy back yen—this bidirectional volatility is attractive even for small investors.

Breaking down Taiwan’s 4 major yen exchange channels: balancing cost and convenience

Many think exchanging yen only involves walking into a bank, but in reality, just the exchange rate difference can cost more than a cup of bubble tea. Based on the latest data, we analyze the costs and suitable scenarios for four channels.

Method 1: Online currency exchange, pick-up at designated branch

No need to open an account. Fill in currency, amount, pick-up branch, and date on the bank’s website. After remittance, bring ID and transaction notification to pick up at the counter. Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (pay only 10 TWD via TaiwanPay), with about 0.5% better exchange rate. Mega International Bank offers similar service, with appointment options at airport branches.

Why is this ranked first? It’s the most economical pre-departure reservation method. Taoyuan Airport has 14 Taiwan Bank outlets (2 open 24 hours), allowing you to withdraw directly before boarding. For an estimated 50,000 TWD exchange, this method costs only 300-800 TWD, much lower than other options.

Advantages: Better exchange rates, often no handling fee, airport pick-up available, no need for foreign currency accounts
Disadvantages: Requires prior reservation (at least 1-3 days ahead), pick-up limited to bank hours, branch cannot be changed
Suitable for: Planned travelers who want to withdraw at the airport

Method 2: Foreign currency ATM cash withdrawal, 24/7 flexibility

Use a chip-enabled bank card to withdraw yen cash from foreign currency ATMs, supporting 24-hour operation and interbank use. E.SUN Bank’s foreign currency ATMs allow withdrawal of yen from TWD accounts, with a daily limit of 150,000 TWD and no currency exchange fee. Other banks like CTBC set a single transaction limit of equivalent TWD 120,000.

The cost of immediacy: No reservation needed, but limited locations (about 200 nationwide), and only major currencies available. During peak times (e.g., before holidays), cash may sell out. It’s recommended to plan 1-2 days ahead rather than last-minute before departure. For an estimated 50,000 TWD, costs are about 800-1,200 TWD.

Advantages: Instant withdrawal, high flexibility, deduct from TWD account with low fee (only 5 TWD interbank fee), 24/7 operation
Disadvantages: Limited locations and denominations (fixed 1,000/5,000/10,000 yen), cash may run out during peak times, currency restrictions
Suitable for: Those without time to visit banks or needing urgent cash

Method 3: Online currency exchange, holding foreign currency accounts

Use online banking or apps to convert TWD into yen and deposit into a foreign currency account, using “spot selling rate” (about 1% better than cash selling rate). If cash is needed later, withdraw at counters or ATMs, but with a currency conversion fee (starting around 100 TWD).

E.SUN Bank’s online exchange feature combined with their foreign currency ATM offers a balanced cost. Suitable for monitoring exchange rates and gradually entering at low points (e.g., when TWD/JPY drops below 4.80).

Advantages: 24-hour operation, ability to buy in installments to average costs, better exchange rates, convenient for future transfers to fixed deposits
Disadvantages: Need to open a foreign currency account first, withdrawal fees (about 5-100 TWD), requires financial literacy
Suitable for: Experienced forex users, those with foreign currency accounts, investors interested in yen deposits

Method 4: In-person cash exchange, the most traditional but highest cost

Bring cash to a bank branch or airport counter to exchange for yen cash. Although simple and with full denominations, it uses “cash selling rate” (about 1-2% worse than spot rate), making it the most expensive overall. Not recommended as the main method.

As of 2025-12-10 09:18, Taiwan Bank’s cash selling rate is about 0.2060 TWD per yen (roughly 4.85). Some banks like E.SUN and Taipei Fubon charge an additional fixed fee of 100-200 TWD. For 50,000 TWD, expected loss is 1,500-2,000 TWD.

Advantages: Safe and reliable, full denominations, staff assistance available
Disadvantages: Worst exchange rate, limited to bank hours (weekday 9:00-15:30), extra handling fees increase costs
Suitable for: Those unfamiliar with online methods or needing small urgent amounts (e.g., at the airport)

Is it worthwhile to exchange yen now? Market outlook

Exchange rate current status and annual performance

As of December 10, 2025, TWD/JPY is about 4.85, up approximately 8.7% from the start of the year’s 4.46. In other words, 100,000 TWD could buy 4.6 million yen early this year, now it can buy 4.85 million yen—an 8.7% gain, quite significant, especially under TWD depreciation pressure.

Short-term fluctuations and medium-long-term forecast

The Bank of Japan (BOJ) Governor Ueda Kazuo recently made hawkish comments, raising interest hike expectations to 80%. The December 19 meeting is expected to raise rates by 0.25 basis points to 0.75% (a 30-year high), with Japanese bond yields reaching 17-year highs of 1.93%. USD/JPY has fallen from a high of 160 early this year to around 154.58 now, with short-term oscillations possibly returning to 155, but medium-long-term forecasts suggest below 150.

Investment advice

Yes, exchanging yen now is advantageous, but consider doing it in stages. Yen, as one of the three major safe-haven currencies, is suitable for hedging against Taiwan stocks’ volatility. However, short-term risks include global arbitrage unwinding, which may cause oscillations of 2-5%. It’s recommended to buy in parts to avoid all-in, capturing favorable rates while reducing risk.

Taiwan’s forex demand increased by 25% in the second half of the year, mainly driven by travel recovery and increased hedging needs—market activity itself affirms the value of yen.

Post-exchange options for value appreciation

After exchanging yen, don’t let your money sit idle with no interest. Based on risk preferences, here are four common options suitable for small investors:

1. Yen fixed deposit (conservative)
E.SUN Bank and Taiwan Bank offer foreign currency accounts, with online transfer into fixed deposits. Minimum 10,000 yen, annual interest 1.5-1.8%, 3-month deposits up to 2%. Suitable for capital preservation and stable cash flow.

2. Yen insurance (medium-term holding)
Cathay and Fubon Life offer yen savings insurance, with guaranteed interest rates of 2-3%, combining protection and growth. Suitable for 5-10 year plans.

3. Yen ETFs (growth-oriented)
Yuanta 00675U, 00703 tracking yen indices, can be bought as fractional shares via securities apps. Management fee 0.4% annually, suitable for periodic investment and risk diversification.

4. Forex trading (swing trading)
Trade USD/JPY, EUR/JPY directly. Platforms like Mitrade offer zero commission, low spreads, 24-hour trading, with stop-loss and take-profit tools. Suitable for those with financial literacy and active management.

While yen is a safe-haven, it also fluctuates bidirectionally. BOJ rate hikes are positive, but global arbitrage unwinding or geopolitical conflicts may suppress it. For investment, yen ETFs can diversify risk; for intraday or swing trading, forex trading is a classic way to capture exchange rate movements.

Common questions about currency exchange

Q: What’s the difference between cash exchange rate and spot rate?
Cash rate is the buy/sell rate banks offer for physical banknotes/coins, convenient for immediate use but usually 1-2% worse than spot rate. Spot rate is the foreign exchange market’s rate for settlement within two business days (T+2), used for electronic transfers and non-cash transactions, closer to international market prices.

Q: How much yen can I get with 10,000 TWD?
Based on Taiwan Bank’s December 10, 2025 rate, cash selling rate about 4.85, 10,000 TWD can buy approximately 48,500 yen. Using the spot selling rate (about 4.87), it’s roughly 48,700 yen, a difference of about 200 yen (roughly 40 TWD).

Q: What ID do I need for in-person exchange?
Taiwanese citizens need ID card + passport; foreigners need passport + residence permit. If pre-booked online, also bring transaction notification. Minors under 20 need parental consent and ID; large amounts (over 100,000 TWD) may require source declaration.

Q: Are there limits for foreign currency ATM withdrawals?
From October 2025, many banks have strengthened anti-fraud measures, with third-party digital accounts limited to 100,000 TWD/day. CTBC’s card limit is equivalent to TWD 120,000 per transaction and per day; Taishin Bank’s limit is 150,000 TWD per transaction and day; E.SUN’s limit is 50,000 TWD per withdrawal (50 banknotes), 150,000 TWD daily. Check with your issuing bank before withdrawal.

Summary: Master the rhythm, currency exchange is no longer difficult

Yen is no longer just pocket money for travel but an asset with hedging and small investment value. Today, with TWD/JPY at 4.85, whether you’re preparing for Japan trips next year or want to hedge against TWD depreciation by moving into yen, following the principles of “staged exchange + don’t just sit idle” can minimize costs and maximize gains.

Beginners are advised to start with the simplest options like “Taiwan Bank online exchange + airport pick-up” or “foreign currency ATM,” then transfer yen into fixed deposits, ETFs, or even try forex swing trading based on needs. This way, you not only save on travel costs but also add a layer of protection amid global market fluctuations.
