Yen Investment and Travel Currency Exchange Guide: The 4 Most Cost-Effective Methods in 2025

Why is the Japanese Yen Worth Paying Attention To?

When the TWD/JPY exchange rate reaches 4.85, many people start to reassess the value of the yen. The demand for the yen actually extends far beyond travel expenses—it is a global safe-haven currency and an asset allocation option.

Travel and Living Needs

Traveling to Japan, shopping, studying abroad, or purchasing Japanese goods via purchasing agents or online auctions all require cash or transfers in yen. Although credit card usage is widespread in Japan, cash acceptance still accounts for about 40%, and many small shops and convenience stores mainly give change in cash.

Financial Hedging Properties

The yen is one of the world’s three major safe-haven currencies alongside the USD and Swiss Franc. During market turbulence, funds flow heavily into the yen. For example, during the Russia-Ukraine conflict in 2022, the yen appreciated 8% in a single week, effectively hedging a 10% stock market decline. For Taiwanese investors, holding yen can reduce the risk of overexposure to the Taiwan stock market.

Additionally, Japan’s central bank has maintained ultra-low interest rates (around 0.5%), making the yen a “funding currency.” Investors often borrow yen at low interest rates to buy higher-yielding USD, exploiting the roughly 4.0% interest rate differential. When risks rise, they unwind positions and buy back yen for profit.

Four Ways to Exchange for Yen in Taiwan and Cost Comparisons

Many think exchanging yen is just a matter of going to the bank, but the exchange rate differences can cost you several cups of bubble tea. Here are the latest four methods as of December 2025:

Method 1: Bank Counter Cash Exchange — The Most Traditional but Costly

Bring cash in TWD to a bank or airport counter and exchange for yen on the spot. This is the safest and most straightforward method, but it uses the “cash selling rate,” which is about 1-2% worse than the spot rate.

Cost Analysis

For example, Taiwan Bank’s rate on December 10, 2025, is 0.2060 TWD/JPY (1 TWD = 4.85 JPY). Exchanging 50,000 TWD:

• Yen received: approximately 242,500 JPY
• Additional costs: 1,500-2,000 TWD (due to exchange margin + possible fees)

Some banks charge fixed handling fees (e.g., E.SUN Bank 100 TWD per transaction, Cathay United Bank 200 TWD), so watch out.

Pros & Cons

Advantages: Simple, safe, full denominations, staff assistance
Disadvantages: Exchange margin, limited operating hours (weekday 9:00-15:30), additional handling fees

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

Method 2: Online Currency Conversion & Transfer — Suitable for Long-term Holders

Use bank apps or online banking to convert TWD to yen and deposit into a foreign currency account. This uses the “spot selling rate” (about 1% better than cash selling rate), then withdraw cash in installments or keep funds in the account.

Cost Analysis

After online currency conversion via E.SUN Bank app, if you withdraw cash, you pay a margin fee (minimum 100 TWD). If you just deposit without withdrawal, costs are minimal.

Exchanging 50,000 TWD:

• Yen received: about 243,500 JPY (better than cash rate)
• Additional costs: 500-1,000 TWD (if withdrawing cash)

Pros & Cons

Advantages: 24/7 operation, ability to average costs over multiple entries, better rates, easy to monitor trends
Disadvantages: Need to open a foreign currency account first, withdrawal fees apply, interbank transfer fee 5-100 TWD

Suitable for: Those experienced with forex, using foreign currency accounts regularly, planning to buy yen deposits (current annual interest 1.5-1.8%)

Method 3: Online Currency Settlement & In-Person Pickup — Airport Travelers’ Favorite

No need for a foreign currency account. Fill in currency, amount, pickup branch, and date on the bank’s website. After transfer, bring ID and transaction notice to pick up in person. Taiwan Bank’s “Easy Purchase” and Mega Bank offer this service.

Features

Taiwan Bank’s online settlement is fee-free (pay 10 TWD via Taiwan Pay), with about 0.5% better exchange rate. The biggest advantage is reservation for pickup at Taoyuan Airport branches—14 Taiwan Bank locations, 2 open 24 hours. Very convenient for travelers.

Exchanging 50,000 TWD:

• Yen received: about 244,000 JPY
• Additional costs: 300-800 TWD (lowest cost)

Pros & Cons

Advantages: Better rates, often no handling fee, can specify airport pickup, easy reservation
Disadvantages: Need to book 1-3 days in advance, pickup limited to operating hours, branch location cannot be changed

Suitable for: Planned travelers, those going abroad, wanting to withdraw directly at the airport

Method 4: Foreign Currency ATM Withdrawal — 24/7 Emergency Solution

Use a chip-enabled debit card at foreign currency ATMs to withdraw yen cash. Supports 24-hour operation and interbank transactions. Deducts only 5 TWD per transaction, lowest cost.

Usage Notes

SinoPac’s foreign currency ATMs allow withdrawal from TWD account with a limit of 150,000 TWD per day, no exchange fee. China Trust’s ATMs limit at 120,000 TWD. About 200 foreign currency ATMs nationwide, far fewer than regular ATMs.

Exchanging 50,000 TWD:

• Yen received: about 242,000-243,000 JPY (depending on ATM rate)
• Additional costs: 800-1,200 TWD (including interbank fee)

Important Tips

Note the fixed denominations (1,000/5,000/10,000 JPY). During peak times (e.g., airports), cash may run out. Don’t wait until the last minute to withdraw, especially in crowded locations.

Pros & Cons

Advantages: Instant withdrawal, high flexibility, 24/7 operation, low interbank fee
Disadvantages: Limited locations (~200), fixed denominations, possible cash shortages at peak times

Suitable for: Those with no time to visit banks or needing urgent cash

Cost Comparison Table of the Four Methods

Based on December 2025 data, for exchanging 50,000 TWD:

Beginner Tips: For budgets of 50,000–200,000 TWD, the most cost-effective combo is “Online settlement + airport pickup” or “Foreign currency ATM + online currency conversion,” saving 500-1,200 TWD.

Is Now a Good Time to Exchange for Yen?

Exchange Rate Status

As of December 10, 2025, TWD/JPY is about 4.85. Compared to 4.46 at the start of the year, it has appreciated roughly 8.7%, providing significant forex gains for Taiwanese investors, especially amid TWD depreciation pressures. Market data shows a 25% increase in forex demand in Taiwan in the second half of the year, driven by travel recovery and hedging needs.

Bank of Japan Rate Hike Expectations

BOJ Governor Ueda Kazuo recently made hawkish comments, boosting market expectations of rate hikes to 0.75% at the December 19 meeting (a 30-year high). The 10-year Japanese government bond yield has hit a 17-year high of 1.93%. This will further support the yen.

USD/JPY has fallen from a high of 160 at the start of the year to around 154.58 now. Short-term fluctuations may return to 155, but medium to long-term forecasts suggest below 150.

Investment Advice

Yes, now is a good time to buy yen, but it’s best to do so in installments. Yen volatility remains high; short-term risks include profit-taking from arbitrage trades, with fluctuations of 2-5%. It’s recommended to stagger purchases to average costs and avoid all-in exposure.

Using December 10, 2025, cash selling rate of 4.85, 10,000 TWD ≈ 48,500 JPY. Using the spot rate (~4.87), about 48,700 JPY. Difference roughly 200 JPY (~40 TWD).

Q: What ID do I need for counter exchange?

Taiwanese: ID card + passport; foreigners: passport + residence permit. For online booking, bring transaction notice. Under 20 need parental consent; large exchanges over 100,000 TWD may require source declaration.

Q: What’s the limit for foreign currency ATM withdrawals?

Varies by bank. China Trust: 120,000 TWD per transaction/day; Taishin Bank: 150,000 TWD per transaction/day; E.SUN Bank: 50,000 TWD per withdrawal (about 50 bills), 150,000 TWD daily. Consider spreading withdrawals or using your own bank card to avoid fees.

Q: How does RMB exchange compare?

Similar to yen, RMB exchange involves counter, online, online settlement, and ATM options. Compare rates and fees; online settlement usually cheapest. Check each bank’s official rates for specifics.

Summary

The yen is no longer just “pocket money” for travel but a safe-haven asset with investment value. Whether preparing for a trip to Japan next year or capitalizing on TWD depreciation, follow the principles of “phased exchange + don’t leave funds idle” to minimize costs and maximize returns.

Beginners should start with the simplest options like “Taiwan Bank online settlement + airport pickup” or “foreign currency ATM,” then diversify into deposits, ETFs, or forex trading as needed. This way, you can enjoy more cost-effective travel and add a layer of protection during global market fluctuations.
