Comprehensive Guide to Japanese Yen Exchange: Comparing the Costs of 4 Methods to Help You Find the Most Cost-Effective Way to Exchange

The NT$ to JPY exchange rate has risen to 4.85 (as of December 10, 2025), reigniting travel to Japan and investment in yen. But the key question is: do you know how to exchange yen to save the most? Different channels have cost differences that could cost you several thousand dollars more. We compare four mainstream currency exchange methods in the market to help you find the most cost-effective way.

Yen is not just for travel, but also an investment tool

When it comes to exchanging foreign currency, many people first think of the yen, but the reason is not just because they like traveling to Japan. From daily life to financial markets, the yen has multi-layered practical value.

Everyday consumption: Japan’s commercial environment still relies heavily on cash (credit card penetration only 60%). Whether shopping in Tokyo, skiing in Hokkaido, or vacationing in Okinawa, you need to prepare yen cash. Consumers purchasing Japanese cosmetics, clothing, gaming peripherals, or planning to study or work in Japan also need to exchange yen in advance to hedge against exchange rate fluctuations.

Financial markets: The yen is one of the world’s three major safe-haven currencies (alongside USD and Swiss Franc), due to Japan’s stable economy and manageable debt levels. During the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a single week, successfully buffering the 10% decline in the stock market. For Taiwanese investors, holding yen is equivalent to adding a protective layer against Taiwan stock market volatility.

Additionally, Japan’s long-term ultra-low interest rate policy (currently 0.5%) makes the yen a “funding currency.” Investors often borrow low-interest yen to arbitrage into higher-yield USD (with a USD/JPY interest rate differential of 4.0%), then close positions when risks rise, buying back yen to lock in profits.

Cost comparison of 4 currency exchange methods

Many think exchanging yen just involves queuing at the bank, but even the exchange rate difference alone can cause costs over a few hundred dollars. Based on the latest rates as of December 10, 2025, we analyze the pros, cons, and real costs of each channel.

Method 1: In-person cash exchange — the most traditional but most expensive

Bring cash NT$ to a bank branch or airport counter to receive yen cash on the spot. This method is simple but uses the “cash selling rate” (lagging about 1-2% behind the spot rate), making it the most costly overall.

For example, Taiwan Bank’s cash selling rate is about 0.2060 NT$/JPY (1 NT$ = 4.85 yen). Some banks charge fixed handling fees. Exchanging NT$50,000 could result in a loss of NT$1,500–2,000.

Suitable for: Small urgent needs, no online operation habit, emergency at the airport.
Limitations: Limited operating hours (weekday 9:00-15:30), additional handling fees, denomination restrictions (1,000, 5,000, 10,000 yen).

Bank cash selling rates (2025/12/10):

• Taiwan Bank: 0.2060 NT$/JPY, no fee
• E.SUN Bank: 0.2067 NT$/JPY, NT$100 per transaction
• E.SUN Bank: 0.2067 NT$/JPY, NT$100 per transaction
• Cathay United Bank: 0.2063 NT$/JPY, NT$200 per transaction

Method 2: Online currency exchange + cash pickup — a balanced approach

Use bank app or online banking to convert NT$ to foreign currency accounts, using “spot selling rate” (about 1% better than cash selling rate). If you need cash, you can withdraw at counters or ATMs, with additional withdrawal fees (around NT$100+).

Many banks like E.SUN, Taishin offer this service. It allows investors to observe exchange rate trends, and during dips (e.g., NT$ to yen below 4.80), to stagger purchases, lowering average costs.

For NT$50,000, estimated loss NT$500–1,000. Suitable for experienced forex traders wanting to diversify entry points.

Advantages: 24/7 self-service, better rates, staggered entry, can transfer to fixed deposits (annual interest 1.5-1.8%).
Disadvantages: Need to open foreign currency accounts in advance, withdrawal fees apply, interbank withdrawal fees NT$5–100.

Method 3: Online currency exchange + airport pickup — the top choice for travelers

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 designated branch for pickup. Taiwan Bank and Mega Bank mainly offer this. You can reserve pickup at Taoyuan Airport (Taiwan Bank has 14 airport locations, 2 open 24 hours).

Taiwan Bank’s “Easy Purchase” online exchange service is fee-free (pay NT$10 via TaiwanPay), with about 0.5% better rates. This is the best pre-travel reservation method. Exchanging NT$50,000 could cost NT$300–800 in losses.

Suitable for: Planning to travel, wanting to pick up cash directly at the airport.
Limitations: Need to book 1-3 days in advance, pickup times limited to bank hours, reservation at a branch cannot be changed on short notice.

Method 4: Foreign currency ATM withdrawal — 24-hour instant solution

Use a chip-enabled bank card at foreign currency ATMs to withdraw yen cash directly. Supports 24/7 service, with interbank withdrawal fee NT$5 (deducted from NT$ account). About 200 ATMs nationwide, but denominations and currency options are limited (mainly 1,000, 5,000, 10,000 yen).

SFCU’s foreign currency ATMs have a daily withdrawal limit of NT$150,000 equivalent, no additional exchange fee. For NT$50,000, estimated loss NT$800–1,200.

Suitable for: Urgent needs, no time to visit banks, night departures.
Notes: Limited locations, fixed denominations, cash may run out during peak times (e.g., airports), plan ahead.

Is it worthwhile to exchange yen now? Dual analysis of rates and interest

As of December 10, 2025, NT$ to yen is at 4.85, up 8.7% from 4.46 at the start of the year. The exchange gain from converting to yen is quite significant. In the second half of 2025, demand for forex in Taiwan increased by 25%, mainly driven by travel recovery and asset hedging.

Short-term rate forecast: The Bank of Japan’s governor Ueda Kazuo recently made hawkish comments, raising expectations of rate hikes to 0.75% (a 30-year high) at the December 19 meeting, with Japanese bond yields reaching 17-year highs of 1.93%. Amid the US easing cycle, USD/JPY has fallen from 160 early in the year to 154.58, likely to oscillate around 155 short-term but converge below 150 in the medium to long term.

Investment advice: While yen has safe-haven attributes, short-term risks include arbitrage unwinding, causing 2-5% volatility. It’s recommended to stagger entry, avoid all-in exchange, and utilize yen interest rates for fixed deposits (1.5-1.8%) or ETF investments for appreciation.

Ways to grow your yen after exchange

If you don’t want idle yen to earn no interest, you can choose the following allocations based on risk appetite:

Conservative — Yen fixed deposit: Open foreign currency accounts at E.SUN, Taiwan Bank, with a minimum of 10,000 yen, annual interest 1.5-1.8%. Suitable for small, capital-preserving investors.

Mid-term — Yen insurance policy: Cathay, Fubon offer yen savings insurance with guaranteed interest rates of 2-3%, combining protection and returns.

Growth — Yen ETFs: Yuanta 00675U, 00703 tracking yen indices, can be bought as fractional shares via broker apps, diversifying currency risk and participating in Japan’s market growth.

Swing trading — Forex trading: Trade USD/JPY or EUR/JPY directly on platforms like Mitrade, with zero commissions, low spreads, long/short options, 24-hour trading, suitable for advanced traders capturing forex fluctuations.

Final thoughts: Yen has become an asset, not just travel money

Yen has long surpassed the role of “pocket money for trips” and evolved into an asset with hedging and appreciation potential. Whether reserving for a trip to Japan next year or hedging against NT$ depreciation, mastering “staggered exchange + not lying flat after exchanging” can minimize costs and maximize gains.

Beginners are recommended to start with “Taiwan Bank online exchange + airport pickup” or “foreign currency ATM,” then transfer yen into fixed deposits, ETFs, or forex swing trading based on goals. This way, you not only enjoy more cost-effective travel but also add a layer of protection amid global market fluctuations.
