JPY Exchange Rate Comparison: The Top 4 Most Cost-Effective Ways to Buy Currency in 2025

Taiwan Dollar to Japanese Yen Reaches 4.85! Is Now a Good Time to Invest?

As we approach the end of 2025, the Japanese Yen once again becomes a focal point for Taiwanese investors and travelers. From an early-year rate of 4.46 to the current 4.85, an accumulated increase of 8.7%, this wave of Yen exchange rate movements reflects a global economic restructuring. Are you ready to hop on this train?

Three Major Reasons Why the Yen Is Worth Investing In

1. Strong demand for travel and consumption

Tokyo, Osaka, Hokkaido, Okinawa—Japan remains Taiwan’s top travel destination. Cash transactions at local stores account for up to 40%, especially drugstores, convenience stores, and small merchants that mostly accept cash only. Purchasing agents, Japanese online shopping, studying abroad, working holidays—all drive continuous Yen purchases by individuals.

2. One of the three major safe-haven currencies

Yen, USD, and Swiss Franc are listed as global safe assets. Japan’s economy is stable, with low debt ratios, and during market turbulence, funds flow into Yen as a safe harbor. During the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in a single week, while the stock market fell 10%. For Taiwanese investors, holding Yen is equivalent to insuring against risks in Taiwan stocks.

3. Arbitrage trading interest rate differential

The Bank of Japan maintains ultra-low interest rates (0.5%) for the long term, while the US Federal Funds Rate reaches 5.25-5.5%, creating an almost 4% US-Japan interest rate gap. This makes Yen a “borrowed currency,” where investors profit from low-interest Yen loans and converting to higher-yield USD. When risks rise, they close positions by buying back Yen, creating cyclical volatility opportunities.

Four Currency Purchase Options with Cost Comparison for 50,000 TWD

Different Yen exchange methods can vary costs by over 30%. For example, purchasing 50,000 TWD worth of Yen:

Option 1: In-person cash exchange (Cost: 1,500-2,000 TWD loss)

Bring TWD directly to a bank or airport counter to exchange for Yen cash. This traditional method is also the most expensive, as it uses the “cash selling rate” (about 1-2% worse than the spot rate).

Example from Taiwan Bank on December 10, 2025:

• Cash selling rate: 1 Yen ≈ 0.2060 TWD (i.e., 1 TWD = 4.85 Yen)
• 50,000 TWD ≈ 242,500 Yen

Some banks charge an additional 100-200 TWD per transaction, increasing total costs.

Suitable for: Urgent airport needs, unfamiliar with online methods

Pros & Cons: Safe and reliable, full denominations; but worse exchange rate, limited operating hours, additional fees

Option 2: Online currency exchange with in-person withdrawal (Cost: 500-1,000 TWD loss)

Use bank apps or online banking to transfer TWD into foreign currency accounts and exchange for Yen (using the spot sell rate, about 1% better than cash). When cash is needed, withdraw in person or at foreign currency ATMs, incurring additional withdrawal fees (from 100 TWD).

E.SUN Bank, CTBC Bank, and others offer this service, allowing phased entry to average costs, especially suitable when TWD/JPY is below 4.80 for gradual accumulation.

Suitable for: Those with FX experience, planning long-term Yen deposits or ETFs

Pros & Cons: 24/7 operation, favorable rates, dollar-cost averaging; requires opening FX accounts, withdrawal fees apply

Option 3: Online currency settlement with airport pickup (Cost: 300-800 TWD loss)

Services like Taiwan Bank’s “Easy Purchase” allow online input of currency, amount, pickup branch, and date. After transfer, you go in person with ID and notification to pick up. Features include reservation at Taoyuan Airport’s 14 branches (including 2 24-hour locations).

Exchange rate advantage of about 0.5%, paying with TaiwanPay costs only 10 TWD, often fee-free. This is the most efficient pre-departure reservation method.

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

Pros & Cons: Favorable rates, often fee-free, airport convenience; requires 1-3 days advance booking, pickup during operating hours

Option 4: Foreign currency ATM instant withdrawal (Cost: 800-1,200 TWD loss)

Use chip-enabled bank cards at foreign currency ATMs to withdraw Yen cash 24/7. Only 5 TWD cross-bank fee from TWD accounts, no currency exchange fee. Some banks like E.SUN have daily withdrawal limits around 150,000 TWD equivalent.

Approximately 200 foreign currency ATMs nationwide, with fixed denominations (1,000/5,000/10,000 Yen), may run out during peak times.

Suitable for: Those with no time for in-person exchange, emergency needs

Pros & Cons: 24/7 instant access, flexible, low cross-bank fees; limited locations, fixed denominations, potential shortages at peak times

Suggested Strategy: For budgets of 50,000–200,000 TWD, a mix of “online currency settlement + ATM withdrawal” is most cost-effective; over 200,000 TWD, consider phased online exchange to diversify costs and timing risks.

Market Timing: Three Major Advantages to Enter Now

Bank of Japan Governor Ueda Kazuo recently signaled a hawkish stance, raising market expectations of rate hikes to 80%. If the December 19 meeting raises rates by 0.25 basis points to 0.75% (a 30-year high), it will push long-term Japanese bond yields near 1.93%, supporting Yen appreciation.

USD/JPY has fallen from a high of 160 at the start of the year to 154.58; short-term may rebound to 155, but medium to long-term forecasts lean toward below 150. Meanwhile, the TWD faces depreciation pressure, so converting to Yen is akin to cashing out part of your assets, protecting purchasing power.

Data from the second half shows Taiwan’s FX demand increased by 25% annually, driven by travel recovery and risk hedging.

After Buying Yen: Four Advanced Strategies

Holding Yen after purchase leaves your money idle and interest-free; consider these allocations:

1. Yen Fixed Deposit (Conservative) E.SUN, Taiwan Bank FX accounts, starting from 10,000 Yen, with annual interest rates of 1.5-1.8%. Stable but limited returns.

2. Yen Insurance Policy (Mid-term Hold) Cathay, Fubon life savings insurance, with guaranteed rates of 2-3%, suitable for locking in funds for 3-5 years.

3. Yen ETFs (Growth Allocation) Yuan Tai 00675U, 00703 tracking Yen index, can be bought as fractional shares via broker apps, suitable for regular investment. Management fee only 0.4% annually, diversifying currency risk.

4. FX Trading USD/JPY (Swing Trading) Trade directly on platforms for USD/JPY or EUR/JPY, with long and short options, 24-hour trading. Low capital requirement, with advanced tools like stop-loss, take-profit, trailing stops, suitable for confident traders.

While Yen is a strong hedge, it still experiences two-way volatility. Global arbitrage unwinding or geopolitical conflicts (Taiwan Strait, Middle East) may temporarily depress prices. For investment, pairing with Yen ETFs for risk diversification is recommended; for intraday trading, USD/JPY is a classic opportunity.

Common Q&A on Yen Exchange

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

Cash Rate (Cash Rate) applies to physical banknotes and coins, with the advantage of immediate delivery but usually 1-2% worse than the spot rate. Spot Rate (Spot Rate) is used for electronic transfers, settled T+2, and closer to international market prices. Simply put, cash rate is convenient but costly; spot rate is cheaper but requires waiting.

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

Depends on the daily rate. Using Taiwan Bank’s December 10 rate of 4.85, 10,000 TWD ≈ 48,500 Yen (cash). Using the spot rate of 4.87, about 48,700 Yen, a difference of 200 Yen (~40 TWD).

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

Taiwanese: ID card + passport; foreigners: passport + residence permit; companies: business registration. For online reservations, also need transaction notification. Under 20 requires parental accompaniment.

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

Post-October 2025, most banks set a daily limit of 100,000-150,000 TWD equivalent for their own cards; other banks follow their issuing bank’s rules. RMB has a special limit of no more than 20,000 RMB per transaction/day. Consider splitting withdrawals or using your own bank card to avoid cross-bank fees.

Conclusion

Yen has evolved from a “pocket money” for travel to an asset class with hedging, investment, and consumption functions. Mastering exchange rate comparisons and choosing the right purchase channels can minimize costs.

The key is “phased entry + not sitting idle after buying”—beginners can start with “Taiwan Bank online settlement + airport pickup” or “foreign currency ATM,” then move into fixed deposits, ETFs, or swing trading based on needs. Not only can you travel more cost-effectively, but you also gain an extra layer of asset protection during global market fluctuations.

By the end of 2025, as the Yen continues to strengthen and safe-haven capital flows in, it’s the best time to reassess Yen asset allocation.
