Japanese Yen Exchange Practical Guide: 4 Major Methods Cost Comparison + Best Entry Timing

Is it worth exchanging for Japanese Yen? Here are 3 reasons to consider first

Many people are accustomed to exchanging TWD for AUD or USD, but JPY is actually more worth including in your personal asset allocation. There are three reasons:

Travel and Consumption Needs
Japan remains Taiwan’s favorite travel destination. Most physical stores in Tokyo, Osaka, and Hokkaido only accept cash or JPY cards, with credit card penetration at only 60%. Purchasing agents, Japanese online shopping, and cosmetics procurement often require direct payment in JPY.

Global Safe-Haven Currency Status
The Japanese Yen is considered one of the three major safe-haven assets alongside USD and Swiss Franc. Japan’s economic fundamentals are stable, and debt levels are low, leading to automatic capital inflows during global market turbulence. For example, during the Russia-Ukraine conflict in 2022, the Yen appreciated 8% in one week, successfully offsetting a 10% stock market decline. For Taiwanese investors, exchanging for Yen is not just for leisure budgets but also a tool for hedging Taiwan stock market risks.

Low-Interest Rate Arbitrage Space
Japan’s long-term ultra-low interest rate policy (only 0.5%) makes the Yen a “funding currency.” Savvy traders often borrow in Yen and convert to higher-yield USD investments (the USD-JPY interest rate differential reaches 4.0%), then close positions when risks rise to profit from Yen appreciation.

4 Practical Exchange Methods Compared

Option 1: Bank Counter Cash Exchange (Most Traditional)

Bring cash TWD to a bank or airport counter to exchange for Yen cash.

Why the exchange rate is worse: Uses “cash selling rate,” which is 1-2% worse than the spot rate. For example, Taiwan Bank’s rate on 2025/12/10 is about 0.2060 TWD/JPY (roughly 4.85 JPY/TWD), plus some banks charge 100-200 TWD handling fee, making the overall cost higher.

Bank cash rates (as of 2025/12/10):

Suitable for: Users unfamiliar with online operations, need small amounts urgently (e.g., upon arrival at the airport), or elderly users.

Option 2: Online Currency Exchange + Counter Pickup (Advanced)

Use bank app or online banking to convert TWD into JPY in a foreign currency account, using “spot selling rate” (about 1% better than cash rate). If cash is needed, withdraw at counters or foreign currency ATMs, paying an additional exchange fee starting from 100 TWD.

Process: Open a foreign currency account → Convert via app → Choose low points for phased entry → Withdraw cash

Suitable for: Those experienced in forex operations, want to average costs over time, or plan to invest in JPY fixed deposits (annual interest 1.5-1.8%).

Option 3: Online Currency Conversion + Airport Pickup (Best Value)

No need to open a foreign currency account beforehand. Fill in amount, branch, and date on the bank’s website. Taiwan Bank’s “Easy Purchase” online currency exchange is fee-free (TaiwanPay payment costs only 10 TWD), with about 0.5% better exchange rate. After completion, bring ID and transaction notification to pick up at the counter, with 24-hour airport locations.

Key advantage: Complete the entire process online before departure, then pick up cash directly at Taoyuan Airport. Taiwan Bank has 14 counters and 2 24-hour branches at Taoyuan Airport.

Suitable for: Planned travelers, those exchanging 1-3 days before departure, or wanting to pick up cash at the airport.

Option 4: Foreign Currency ATM Self-Service Withdrawal (Most Flexible)

Use a chip-enabled debit card at foreign currency ATMs to withdraw Yen, supporting 24/7 cross-bank operations. E.SUN Bank’s foreign currency ATMs allow direct withdrawal from TWD accounts, with a daily limit of 150,000 TWD and no exchange fee, cross-bank fee only 5 TWD.

Note: There are about 200 foreign currency ATMs nationwide; during peak times (e.g., airport rush hours), cash may run out. It’s recommended not to wait until the last minute to withdraw.

Suitable for: Those without time for counter visits, need emergency cash, or are accustomed to self-service.

Is it a good time to exchange for Yen now? Timing guide

Current rate: As of 2025/12/10, TWD/JPY is about 4.85, up 8.7% from early this year’s 4.46. Compared to exchanging for AUD, Yen offers better safe-haven properties and volatility opportunities.

Short to medium-term outlook:

• Bullish factors: The Bank of Japan is on the verge of raising interest rates. Governor Ueda’s hawkish comments have pushed market expectations to 80%, with a December 19 meeting expected to raise rates by 0.25 basis points to 0.75% (30-year high). Japanese bond yields have hit a 17-year high of 1.93%.
• Volatility risks: The US entering a rate cut cycle might support the Yen, but global arbitrage unwinding could cause turbulence of 2-5%. USD/JPY has fallen from a high of 160 early this year to 154.58, with a short-term test of 155 possible, and a long-term forecast below 150.

Exchange advice:
✓ Yes, now is a good time to exchange, but do it in phases
✓ Enter in three installments, spaced 1-2 weeks apart, to average costs
✓ Avoid exchanging all at once to prevent buying at short-term highs

Next steps after exchanging Yen: Avoid “lying flat”

After exchanging Yen, keep your funds growing:

1. Yen Fixed Deposit (Conservative): Annual interest 1.5-1.8%, via E.SUN/Bank of Taiwan foreign currency accounts, starting from 10,000 Yen.

2. Yen Insurance Policy (Mid-term): Cathay or Fubon savings insurance, guaranteed interest rate 2-3%.

3. Yen ETFs (Growth): Yuanta 00675U tracking Yen index, annual management fee 0.4%, suitable for dollar-cost averaging.

4. Forex Trading (Swing): Directly trade USD/JPY or EUR/JPY, long and short, 24-hour trading, suitable for capturing exchange rate fluctuations.

Summary

The Yen has long surpassed the role of “travel pocket money” and has become an asset allocation tool with hedging functions and small investment value. Whether preparing for next year’s Japan trip or capitalizing on TWD depreciation to hedge with Yen, following the “phased exchange + immediate investment” dual approach can minimize costs and maximize returns. Beginners are advised to start with “Taiwan Bank online exchange + airport pickup” or “foreign currency ATM,” then transition into fixed deposits, ETFs, or swing trading based on needs. This not only makes traveling more cost-effective but also adds a layer of asset protection during global market turbulence.
