Japanese Yen Exchange Guide | 4 Methods Full Comparison, The Most Cost-Effective Way to Exchange 50,000 TWD

Taiwan dollar to Japanese yen has already risen above 4.85, and Japan travel will be hot again next year. But do you know? Relying solely on exchange rate differences can cause you to spend thousands of unnecessary dollars. We will compare four ways to exchange for Japanese yen in the market, using real rates to tell you exactly how to exchange wisely.

Why exchange for Japanese yen? Not just for traveling

When it comes to currency exchange, Taiwanese people’s first reaction is JPY. But the用途 of the yen has long exceeded “travel pocket money.”

Travel, shopping, purchasing needs
Many places in Japan still mainly accept cash (credit card penetration is only 60%), especially shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa. People who like buying Japanese cosmetics, clothing, or anime merchandise often need to pay directly in yen to agents or Japanese websites.

Financial market perspective: JPY as a safe-haven currency
The yen has long been one of the three major safe-haven currencies (alongside USD, Swiss Franc, and JPY) because Japan’s economy is stable and debt is well-managed. Whenever global markets shake, funds flow into the yen for safety—during the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a week, buffering a 10% stock market decline. For Taiwanese investors, exchanging for yen is like buying “insurance” for Taiwan stocks.

Plus, Japan maintains ultra-low interest rates (only 0.5%), creating arbitrage opportunities. Many investors borrow low-interest yen to switch into higher-yield USD investments (the USD/JPY interest rate gap is 4.0%). When market risks rise, they close the position and buy back yen for arbitrage. So, yen is not only essential for travel but also an investment option.

Four methods to exchange for yen: a head-to-head comparison

Many think exchanging yen just involves going to the bank, but choosing different methods can lead to cost differences of over 1500 yuan. Here are the latest data as of December 2025:

Method 1: Bank counter cash exchange｜Most traditional but most loss

Bring cash NT dollars to a bank branch or airport counter and exchange for yen cash on the spot. It sounds safest, but the cost is highest—using the “cash selling rate,” which is about 1-2% worse than the spot rate.

For example, Taiwan Bank’s rate on December 10, 2025, is 0.2060 TWD/JPY (equivalent to 1 TWD = 4.85 JPY). Exchanging 50,000 TWD results in a loss of about 1500-2000 yuan. Some banks also charge handling fees, making it worse.

Pros: Safe, denominations available, staff assistance
Cons: Worst exchange rate, limited business hours (9:00-15:30), possible extra fees
Suitable for: Urgent small amounts, those unfamiliar with online operations

Method 2: Online currency exchange + in-person withdrawal｜Suitable for those with foreign currency accounts

Use bank app or online banking to convert TWD into yen and deposit into a foreign currency account, using the “spot selling rate” (about 1% better than cash selling rate). If cash is needed, go to the counter or foreign currency ATM to withdraw, but withdrawal incurs exchange fee (starting at NT$100).

The advantage is you can buy in installments, waiting for favorable rates (e.g., TWD/JPY below 4.80) to average the cost.

Pros: 24/7 operation, installment buying, better rates
Cons: Need to open a foreign currency account first, withdrawal fees (interbank NT$5-100)
Suitable for: Those experienced with forex, regular foreign currency account users, also for investing in yen deposits (current annual interest 1.5-1.8%)

Method 3: Online currency settlement + airport pickup｜Best pre-departure plan

No need for a foreign currency account, just 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 and Mega International Bank offer this service, with airport pickup reservations available.

Taiwan Bank’s “Easy Purchase” online settlement is fee-free (pay NT$10 via TaiwanPay), with about 0.5% better rate. Taoyuan Airport has 14 Taiwan Bank counters, 2 of which operate 24 hours, making it super convenient to pick up cash before departure.

Pros: Better rates, often no fees, airport pickup option
Cons: Need to book 1-3 days in advance, pickup limited to business hours, branches cannot be changed
Suitable for: Planned travelers wanting to pick up cash at the airport

Method 4: Foreign currency ATM withdrawal｜Fast 24-hour solution

Use a chip-enabled debit card at foreign currency ATMs to withdraw yen cash, supporting 24/7 operation and interbank withdrawals. Deduct NT$5 interbank fee from TWD account, very cost-effective. E.SUN Bank’s foreign currency ATMs allow yen withdrawal with a daily limit of NT$150,000, no exchange fee.

Disadvantages are limited ATM locations (about 200 nationwide) and limited denominations. Avoid waiting until the last minute, as cash may run out during peak times (especially at airports).

Pros: Instant withdrawal, 24/7 flexibility, low interbank fee, deduct from TWD account to save costs
Cons: Limited locations and denominations (fixed 1000/5000/10000 JPY), cash shortages at peak times
Suitable for: People with no time to visit banks, urgent cash needs

Cost comparison table of four methods

Recommended combo: For budgets of NT$50,000-200,000, mixing “online settlement + ATM” is most cost-effective. Reserve part via online settlement, supplement with ATM for urgent needs, minimizing fees and maximizing flexibility.

Is it a good time to exchange yen now? Market timing analysis

As of December 10, 2025, TWD/JPY is about 4.85, up from 4.46 at the start of the year, appreciating 8.7%. For Taiwanese investors, the exchange gain is quite substantial. In the second half of 2025, Taiwan’s forex demand increased by 25%, mainly from travel recovery and hedging needs.

Short-term volatility potential
JPY exchange rate still fluctuates widely. The Bank of Japan’s Governor Ueda has recently signaled a hawkish stance, with market expectations of an 80% chance of rate hikes. 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 160 at the start of the year to around 154.58, with short-term fluctuations possibly returning to 155, but medium to long-term forecasts suggest below 150.

Investment advice
As a safe-haven currency, yen is suitable for hedging Taiwan stock volatility, but short-term risks include 2-5% fluctuations when closing arbitrage positions. Use installment buying, avoid all-in exchange. Consider 3-4 partial exchanges to diversify risk and average costs.

Quick FAQ

Q: What’s the difference between cash rate and spot rate?
Cash rate is the buy/sell rate banks offer for physical cash (bills/coins), with the advantage of immediate delivery; but it’s 1-2% worse than the spot rate. Spot rate is the foreign exchange market rate for settlement within two business days (T+2), mainly used for electronic transfers, closer to international market prices.

Q: How much yen can I get for NT$10,000?
Use the formula【JPY amount = TWD amount × current rate】. For example, Taiwan Bank’s rate on December 10, 2025, is 4.85, so NT$10,000 ≈ 48,500 JPY. Using the spot sell rate of 4.87, it’s about 48,700 JPY, a difference of 200 JPY (roughly NT$40).

Q: What do I need to bring for counter transfer and cash exchange?
For cash exchange: Bring ID + passport (for locals) or passport + residence permit (foreigners). If pre-booked online, also bring transaction notice. For corporate exchange, bring business registration. Under 20 needs parent consent; large amounts over NT$100,000 may require source declaration.

For transfer: Mainly account info verification; if transferring to a foreign currency account, provide account number. After online settlement, bring ID + transaction notice to pick up cash.

Q: Are there limits for foreign currency ATM withdrawals in Taiwan?
From October 2025, several banks have adjusted limits due to anti-fraud measures. CTBC, Taishin Bank limit NT$120,000-150,000/day; E.SUN Bank limit NT$150,000/day. Use your own bank card to avoid NT$5 cross-bank fee. Plan ahead during peak times to prevent cash shortages.

Summary｜Yen is not just for travel, but an asset allocation

Yen is no longer just “travel pocket money,” but an asset with hedging and investment value. Whether preparing for Japan trips next year or capitalizing on TWD depreciation to hedge with yen, following the principles of “gradual exchange + not sitting idle after exchange” can minimize costs and maximize returns.

Beginners are advised to start with “Taiwan Bank online settlement + airport pickup” or “foreign currency ATM,” then move into deposits, ETFs, or forex swing trading based on needs. This way, you can enjoy more cost-effective travel and add a layer of asset protection during global market fluctuations.
