Yen Exchange Rate Showdown: 4 Tips to Save the Most, 2025 Latest Cost Analysis

As of December 10, 2025, the TWD to JPY exchange rate has surged to 4.85. Should you exchange now? Instead of blindly following the trend, it’s better to understand the differences among the four currency exchange channels. We use actual rates to compare the real costs of over-the-counter, online currency exchange, and foreign currency ATM options—using the same NT$50,000, choosing the wrong method could cost you an extra NT$2,000.

Why is it worth exchanging for JPY? It’s not just about traveling abroad

When it comes to exchanging foreign currency, Taiwanese people’s first instinct is JPY. But behind this trend are two main drivers.

Travel and daily consumption needs

Shopping in Tokyo, skiing in Hokkaido, vacation in Okinawa—Japan still relies heavily on cash transactions (credit card penetration is only 60%), purchasing Japanese cosmetics and clothing requires JPY payments, and students planning to study or work abroad often lock in exchange rates in advance. These are stable sources of JPY demand.

A new role in financial hedging

The Japanese yen has long been one of the world’s three major safe-haven currencies (alongside USD and Swiss Francs), due to Japan’s stable economy and low debt. During the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a week, successfully buffering the 10% decline in the stock market. For Taiwanese investors, exchanging for JPY is not just for consumption but also a hedging tool against Taiwan stock market volatility. Plus, the Bank of Japan is on the verge of raising interest rates—Governor Ueda and hawkish comments have pushed market expectations to 80%, with a rate hike of 0.25 basis points to 0.75% expected at the December 19 meeting (a 30-year high). Japanese government bond yields have hit a 17-year high 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 may rebound to 155, but medium to long-term forecasts are below 150.

The true costs of 4 currency exchange methods

Choosing the right channel alone can save you a lot of handling fees. Here’s the real situation for each option.

Option 1: Bank over-the-counter cash exchange—most traditional, highest cost

Carrying NT$ cash to a bank or airport counter to get JPY cash on the spot. It sounds simple, but banks use the “cash selling rate” (1-2% worse than the spot rate), plus some banks charge additional handling fees, making the overall cost noticeably higher.

For example, Taiwan Bank’s rate on December 10, 2025, is about 0.2060 NT$/JPY (roughly 4.85 JPY per NT$). With NT$50,000, you get about 48,500 JPY. Using the spot rate (about 4.87), you should get around 48,700 JPY—about 200 JPY less. Although seemingly small, this means you paid more. Some banks also charge handling fees up to NT$200.

Bank cash selling rates and in-person handling fees (2025/12/10):

Suitable for: People unfamiliar with online operations or needing small, urgent exchanges (e.g., at the airport).

Option 2: Online currency exchange + in-person withdrawal—flexible in batches, moderate cost

Use online banking app to convert NT$ into JPY and deposit into a foreign currency account, using the “spot selling rate” (about 1% better than cash selling). If you need cash, withdraw in person or via foreign currency ATM, but this incurs a spread handling fee (from NT$100).

This method allows you to observe exchange rate trends and buy in batches at low points. For example, waiting until NT$ to JPY drops below 4.80 before exchanging could save a lot. After exchanging via E.SUN Bank app, the fee for withdrawing JPY cash is just the difference between spot and cash rates, starting at NT$100.

Suitable for: Those experienced with forex, frequent foreign currency account users, or planning to invest in JPY deposits (current annual interest rate around 1.5-1.8%).

Option 3: Online currency exchange + airport pickup—most cost-effective pre-arranged plan

Favored by many experienced users. No need to open a foreign currency account in advance. Just fill in currency, amount, pickup branch, and date on the bank’s website. After completing online exchange, bring ID and transaction notice to pick up.

Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (pay NT$10 via TaiwanPay), with about 0.5% better rates. You can reserve pickup at Taoyuan Airport branches, which have 14 Taiwan Bank locations, including 2 open 24 hours—very convenient before departure. Mega Bank offers similar service.

Using this method for NT$50,000, the minimum cost loss is NT$300-800.

Suitable for: Planning travelers who want to pick up cash directly at the airport.

Option 4: Foreign currency ATM—instant 24/7 access, but limited locations

Use chip-enabled debit/credit cards to withdraw JPY cash at foreign currency ATMs, supporting 24-hour operation and interbank withdrawals. Deduct NT$5 per transaction from your NT$ account, no forex handling fee. Sinopac’s foreign currency ATM allows NT$150,000 daily withdrawal limit.

The downside is that there are only about 200 foreign currency ATMs nationwide, with limited denominations (fixed 1,000/5,000/10,000 JPY), and cash may run out during peak times (especially at airports). Still, for urgent needs, the 24/7 flexibility is unbeatable.

Bank foreign currency ATM withdrawal limits (new rules after October 2025):

Suitable for: People who don’t have time to visit banks or need quick cash.

Is it worthwhile to exchange for JPY now? Latest rate analysis

Current exchange rate situation

On December 10, 2025, NT$ to JPY is about 4.85, up from 4.46 at the start of the year, an appreciation of approximately 8.7%. This indicates significant forex gains for Taiwanese investors, especially amid NT$ depreciation pressures. Observations show that in the second half of the year, forex demand in Taiwan increased by 25%, mainly driven by travel recovery and hedging needs.

Short-term and medium-long-term outlook

In the short term, USD/JPY remains volatile. The US entering a rate cut cycle may support the yen, but the Bank of Japan is on the verge of rate hikes—recent hawkish comments by Governor Ueda have raised market expectations to 80%. USD/JPY has fallen from a high of 160 to around 154.58; a short-term rebound to 155 is possible, but the medium-long-term forecast is below 150.

For investment purposes, JPY as a major safe-haven currency is suitable for hedging Taiwan stock market fluctuations. However, short-term risks include a 2-5% volatility from arbitrage unwinding. It’s recommended to buy in batches and avoid all-in exchanges.

Summary

The JPY is no longer just for travel “pocket money” but also a hedging asset with small investment value. The NT$ to JPY rate has risen from 4.46 to 4.85 this year, an 8.7% increase, clearly indicating the trend.

This way, you can enjoy more cost-effective trips and add a layer of protection amid global market fluctuations.
