How to choose currency exchange for Japanese Yen? Key decision guide for TWD to JPY at 4.85

In December 2025, the exchange rate of TWD to JPY reaches 4.85. This timing is crucial for those planning to travel abroad or allocate assets in yen. But before that, you need to clarify one question: what is the best way to exchange yen to minimize costs?

Why is it worth exchanging for yen? It’s not just about travel

Many people think of yen as just pocket money for trips abroad, but in reality, the role of yen goes far beyond that.

Travel and daily consumption—Japan still has many cash-based transactions, such as shopping in Tokyo and Osaka, ski resorts in Hokkaido, or Okinawa resorts. Credit card penetration is only about 60%, so cash remains king. Purchasing agents, Japanese online shopping, and long-term students often need to pay directly in yen.

More importantly, the financial aspect—the yen is one of the three globally recognized safe-haven currencies (the other two are USD and Swiss Franc). Japan’s economy is stable, with low debt levels. Whenever global markets are turbulent, capital flows into yen. During the Russia-Ukraine conflict in 2022, the yen appreciated by 8% in a week, while the stock market fell 10%—for Taiwanese investors, holding yen adds a layer of protection against Taiwan stock market volatility.

Moreover, the Bank of Japan has maintained ultra-low interest rates (currently 0.5%) for a long time, making yen a “funding currency.” Many international investors borrow low-interest yen to buy higher-yielding USD (the USD/JPY interest rate differential is about 4.0%). When market risks increase, these carry trades are unwound, further pushing up the yen’s value.

Four currency exchange channels with significant cost differences

The key point: choosing the wrong exchange method can cost you thousands of TWD in spread and fees. We’ve summarized four main channels, breaking down costs with real market rates.

Method 1: Bank branch or airport counter exchange

Bring cash TWD to a bank branch or airport counter to exchange for yen cash. It seems the simplest, but it’s the most expensive. Banks use “cash selling rates,” which are 1-2% worse than the spot market rate. For example, Taiwan Bank’s rate on December 10, 2025, is about 0.2060 TWD/JPY (1 TWD = 4.85 JPY). Some banks also charge an additional handling fee, up to 200 TWD per transaction.

Advantages: Safe, denominations available, staff assistance on-site
Disadvantages: Worse exchange rate, limited operating hours (weekday 9:00-15:30), higher withdrawal fees
Estimated cost (50,000 TWD): loss of 1,500–2,000 TWD
Suitable for: Urgent small amounts, unfamiliar with online methods

Comparison of bank cash selling rates (2025/12/10):

• Taiwan Bank: 0.2060 TWD/JPY, no fee
• E.SUN Bank: 0.2058 TWD/JPY, 100 TWD per transaction
• E.SUN Bank: 0.2067 TWD/JPY, 100 TWD per transaction
• Taipei Fubon Bank: 0.2069 TWD/JPY, 100 TWD per transaction

Method 2: Online account opening + in-person withdrawal

Use bank app or online banking to convert TWD to JPY and deposit into a foreign currency account, enjoying an “instant spot sell rate” (about 1% better than cash selling rate). Then, go to a branch or ATM to withdraw cash. Withdrawal incurs spread fees, usually starting from 100 TWD.

This method allows you to observe exchange rate trends and buy in batches at lower points, averaging costs. For example, when TWD/JPY drops below 4.80, you can buy gradually.

Advantages: 24/7 operation, batch entry, better rates
Disadvantages: Need to open a foreign currency account first, withdrawal fees (interbank 5-100 TWD)
Estimated cost (50,000 TWD): loss of 500–1,000 TWD
Suitable for: Those experienced in forex investment, with foreign currency accounts

Method 3: Online currency exchange + airport pickup

No need to open 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 the branch for pickup. Taiwan Bank’s “Easy Purchase” service offers this, with payment via Taiwan Pay costing only 10 TWD, and about 0.5% better exchange rate. You can specify airport branches for pickup.

Ideal for planned trips—Taoyuan Airport has 14 Taiwan Bank outlets, two of which operate 24 hours, saving queuing time.

Advantages: Better rates, often no fees, convenient airport pickup
Disadvantages: Need to book 1-3 days in advance, pickup limited to bank hours
Estimated cost (50,000 TWD): loss of 300–800 TWD
Suitable for: Well-planned travelers who want to withdraw at the airport

Method 4: 24-hour foreign currency ATM withdrawal

Use a chip-enabled debit card to withdraw yen cash directly from foreign currency ATMs. Supports 24/7 operation, with only 5 TWD fee for interbank transactions. E.SUN Bank’s foreign currency ATMs allow withdrawal from TWD accounts, with a daily limit of 150,000 TWD and no additional forex fee.

Disadvantages include limited locations (about 200 nationwide), fixed denominations (1,000, 5,000, 10,000 JPY), and cash shortages during peak times.

Advantages: Instant 24/7 withdrawal, flexible, low interbank fees
Disadvantages: Limited locations, fixed denominations, possible cash shortages
Estimated cost (50,000 TWD): loss of 800–1,200 TWD
Suitable for: Urgent needs, no time to visit bank

Comparison table of four methods

Is it worthwhile to exchange yen now? Yes, but in batches

As of December 10, 2025, TWD/JPY is 4.85, meaning 1 TWD = 4.85 JPY. Compared to the start of the year at 4.46, it has appreciated about 8.7%, which is a good forex gain for Taiwanese investors. Especially under the ongoing TWD depreciation pressure, staggered yen purchases are valuable.

Recent data shows a 25% increase in Taiwan’s forex demand in the second half of the year, driven by travel recovery and hedging needs.

But the key is to operate in batches. The yen’s exchange rate fluctuates significantly. The Fed’s easing cycle supports the yen, and the Bank of Japan is about to raise interest rates—recent hawkish comments by Governor Ueda have pushed market 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 at the start of the year to around 154.58 now. Short-term fluctuations may bring it back to 155, but medium to long-term forecasts suggest below 150. For investment purposes, staggered entry can effectively hedge short-term volatility (oscillations of 2-5%).

After exchanging yen, don’t let it sit idle

Getting yen is just the beginning; the key is to generate returns. Here are four options suitable for small-scale beginners:

Yen fixed deposit—a stable option. Open a foreign currency account at E.SUN or Taiwan Bank, deposit online, with a minimum of 10,000 yen, annual interest rate 1.5–1.8%.

Yen savings insurance policy—medium-term holding. Offered by Cathay or Fubon Life, with guaranteed interest rates of 2–3%.

Yen ETFs (such as 00675U, 00703)—growth-oriented. Track yen indices, can be bought in fractional shares via brokerage apps, suitable for dollar-cost averaging.

Yen forex swing trading—directly trade USD/JPY or EUR/JPY on forex platforms, supporting both long and short positions, 24-hour trading.

While yen has hedging attributes, it also has two-way volatility. Rate hikes are positive, but global arbitrage unwinding or geopolitical conflicts (Taiwan Strait, Middle East) may weigh on it. For investment, yen ETFs (like 00675U, with an annual management fee of 0.4%) can diversify risk. For intraday or swing strategies, USD/JPY or EUR/JPY are classic ways to capture exchange rate movements.

Common questions about cash withdrawal

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

Cash rate is the buy/sell rate banks offer for physical cash (banknotes and coins). It’s convenient for immediate delivery and portability but is 1-2% worse than the spot rate, plus withdrawal fees, making it more costly overall.

Spot rate is the exchange rate for transactions settled within two business days in the forex market, used for electronic transfers and non-cash settlements. It’s closer to the international market price but requires T+2 settlement.

Q: How much yen can I get with 10,000 TWD?

Calculation: Yen amount = TWD amount × current rate(TWD/JPY)

Using Taiwan Bank’s cash selling rate of 4.85 on December 10, 2025, 10,000 TWD ≈ 48,500 JPY. Using the spot rate of about 4.87, it’s roughly 48,700 JPY, a difference of about 200 JPY (roughly 40 TWD).

Q: What ID do I need for in-person exchange?

Taiwanese: ID card + passport. Foreigners: passport + residence permit. If pre-booked online, bring transaction notice. Under 20, need parental consent and ID. For large amounts (over 100,000 TWD), may need to declare source of funds.

Q: Are there limits on foreign currency ATM withdrawals?

From October 2025, limits are adjusted as follows:

It’s recommended to split withdrawals or use your own bank card to avoid cross-bank fees. During peak times (like airports), cash may run out quickly—plan ahead.

Summary: Batch exchange + continuous asset growth

Yen is no longer just travel “pocket money,” but an asset with hedging and investment value. Whether for next year’s trip to Japan or asset allocation amid TWD depreciation, applying the principles of “batch exchange” and “don’t let it sit idle” can minimize costs.

Beginners are advised to start with “Taiwan Bank online currency exchange + airport pickup” or “foreign currency ATM,” then transfer yen into fixed deposits, ETFs, or small swing trades based on needs. This way, you can enjoy more cost-effective travel and add a layer of protection during global market turbulence.
