Japanese Yen Exchange Guide: 3 Steps to the Most Cost-Effective Solution

The NT$ to JPY exchange rate has reached 4.85, and many people want to take this opportunity to exchange for yen. But did you know? Exchanging NT$50,000 through different methods can result in a difference of up to NT$2,000—enough to enjoy several meals in Tokyo.

Instead of blindly rushing to the bank, it’s better to understand the differences among four currency exchange channels. This article summarizes the latest rates, fee comparisons, and subsequent investment operations for the Japanese yen.

Why should you pay attention to the yen now?

The yen holds three major roles in the global investment market:

Practical travel currency: Cash consumption in Japan remains high, with only about 60% of transactions via credit card. Traveling in Tokyo, Osaka, or Hokkaido requires cash preparedness.

Hedging asset: The US dollar, Swiss franc, and yen are the three major safe-haven currencies worldwide. During the Russia-Ukraine conflict in 2022, the yen appreciated by 8% in one week, successfully buffering stock market declines. For Taiwanese investors, holding yen can hedge against Taiwan stock risks.

Arbitrage trading target: The Bank of Japan has maintained an ultra-low interest rate (0.5%) for a long time, leading many investors to borrow low-interest yen and invest in higher-yield USD. According to the latest data, the US-Japan interest rate differential is about 4.0%, presenting an arbitrage opportunity—when risks increase, traders close positions by buying back yen, pushing up the yen’s price.

Regarding exchange rates, many only know the NT$ to yen rate, but changes in the USD to NT$ rate (around NT$32) also indirectly influence the yen’s trend, as the yen often gains when the dollar appreciates.

Four practical currency exchange channels compared

1. Bank counter cash exchange (most traditional but most expensive)

Bring NT$ cash directly to the bank or airport counter to exchange for yen. It sounds simple, but it uses the “cash selling rate,” which is 1-2% worse than the international market rate, plus handling fees, making it the most costly option.

For example, Taiwan Bank’s rate as of December 10, 2025, is about NT$0.2060 per yen (i.e., NT$1 exchanges for 4.85 yen). Some banks also charge an additional NT$100-200 handling fee.

Advantages: Safe, full denominations, staff assistance
Disadvantages: Worst exchange rate, limited to business hours (Weekdays 9:00-15:30)
Suitable for: Urgent airport needs, those unfamiliar with online operations

Below are the cash selling rates and handling fees for various banks as of December 10, 2025:

2. Online currency exchange + counter withdrawal (requires foreign exchange account)

Use bank app or online banking to convert NT$ into yen, deposit into a foreign currency account, and get a better “spot sell rate” (about 1% better than cash selling). If you want cash, you can withdraw at counters or via foreign currency ATMs, but additional fees apply.

This method suits those experienced with forex operations who want to buy in batches for average cost. When NT$ to yen drops below 4.80, you can buy gradually.

Advantages: 24-hour operation, dollar-cost averaging, better rates
Disadvantages: Need to open a foreign currency account, withdrawal fees (about NT$5-100)
Suitable for: Regular foreign currency account users, those investing in yen deposits

3. Online currency exchange + airport pickup (most recommended)

The smartest way. Book currency exchange directly on the bank’s website, fill in the amount, pick-up branch and date, then bring ID and transaction notification to pick up in person. Taiwan Bank and Mega Bank offer this service, with the convenience of pre-booking for Taoyuan Airport.

Taiwan Bank’s “Easy Purchase” online exchange has no handling fee (using Taiwan Pay costs only NT$10), with about 0.5% better rates. Taoyuan Airport has 14 pickup points (including 2 24-hour outlets). Book the night before departure, pick up on the day of travel—saving time and money.

Advantages: Better rates, often no handling fee, airport pickup, plan ahead
Disadvantages: Need 1-3 days for booking, pickup during business hours, branch changes not allowed
Suitable for: Well-planned travelers wanting to exchange in advance

4. Foreign currency ATM (24-hour emergency plan)

Use chip-enabled financial cards to withdraw yen cash at foreign currency ATMs. Supports 24-hour operation, with a NT$5 fee for interbank withdrawals. About 200 locations nationwide, mainly in urban areas.

SinoPac’s foreign currency ATMs allow yen withdrawals with a daily limit of NT$150,000, no exchange fee. Note that Japan’s ATM withdrawal services will be adjusted by the end of 2025; international withdrawals require Mastercard/Cirrus cards.

ATM denominations are fixed (1000/5000/10000 yen). During peak times (especially airports), cash may run out, so avoid waiting until the last minute.

Advantages: Instant withdrawal, 24/7 access, deduct from NT$ account to save costs
Disadvantages: Limited locations, fixed denominations, possible out-of-stock during peak times
Suitable for: Urgent needs, those with no time to visit banks

Cost comparison of the four methods

For exchanging NT$50,000:

Conclusion: For budgets of NT$50,000-200,000, the most cost-effective approach is a combination of online currency exchange + airport pickup or foreign currency ATM; large amounts should use online exchange; for last-minute needs, use foreign currency ATM.

Is now a good time to exchange? Market timing analysis

As of December 10, 2025, NT$4.85 to yen, up 8.7% from NT$4.46 at the start of the year, providing a significant exchange gain. In the second half of 2025, Taiwan’s currency exchange demand grew by 25%, mainly driven by travel recovery and hedging needs.

Exchange rate outlook:

The Bank of Japan is on the verge of raising interest rates. Governor Ueda recently signaled a hawkish stance, with market expectations of an 80% chance of a rate hike at the December 19 meeting, raising by 0.25 bps to 0.75% (a 30-year high). Japanese bond yields hit a 17-year high of 1.93%.

The US is entering a rate-cut cycle, with USD/JPY falling from a high of 160 at the start of the year to around 154.58 now. Short-term may test 155, but medium to long-term forecasts suggest below 150.

Investment advice: Although the yen is a safe-haven currency, suitable for hedging Taiwan stock risks, short-term risks involve arbitrage closing—when investors repay yen loans, causing volatility of 2-5%. The safest approach is to gradually enter and avoid all at once.

What to do after exchanging yen? Don’t let your money sit idle

After acquiring yen, instead of leaving it idle and earning no interest, consider small investments:

Yen deposits: Most stable. E.SUN/Taiwan Bank offer foreign currency accounts, with a minimum of NT$10,000 and annual interest rates of 1.5-1.8%.

Yen insurance policies: Medium-term holdings. Cathay Fubon Life offers savings insurance with guaranteed 2-3% interest.

Yen ETFs (e.g., 00675U, 00703): Growth-oriented options. Yuanta 00675U tracks the yen index, available for fractional investing via broker apps. Management fee is 0.4% annually, diversifying risk.

Yen forex trading: Directly trade USD/JPY or EUR/JPY on forex platforms, suitable for capturing swing trends. Advantages include two-way trading, 24-hour access, and small capital requirements—ideal for experienced investors.
