Yen exchange guide: 4 most cost-effective ways to convert 50,000 to 200,000 TWD

December 10, 2025, the Taiwanese dollar (TWD) against the Japanese yen (JPY) reaches a critical level of 4.85. As the Bank of Japan prepares to raise interest rates, market risk aversion increases, coupled with the rising pressure of TWD depreciation, the topic of JPY exchange rates has once again become hot.

However, many people still stick to the old method of “running to the bank counter for currency exchange,” unaware that just the exchange rate difference can cost you the price of an extra bubble tea. Today, we will explain the four latest exchange channels in detail, so whether for travel or investment, you can find the most economical solution.

Why is the Japanese yen worth paying attention to?

The JPY is definitely the most commonly encountered foreign currency among Taiwanese people, but its uses go far beyond your imagination.

From daily life, in consumption scenes in Tokyo, Osaka, and Hokkaido, cash remains the main payment method (credit card penetration is only 60%), which means travelers must prepare cash JPY. Additionally, for purchasing via proxy, shopping on Japanese websites, or even considering working holiday plans, currency exchange issues are unavoidable.

From a financial perspective, the JPY is one of the world’s three major safe-haven currencies (alongside the USD and Swiss Franc). Japan’s economy is stable, with a relatively healthy debt structure. Whenever geopolitical conflicts escalate (such as the Russia-Ukraine war in 2022), capital flows into the yen as a safe haven, with the yen appreciating 8% within a week, enough to buffer a 10% stock market decline. For Taiwanese investors, holding JPY is like adding an insurance layer to their Taiwan stocks.

Another angle is arbitrage opportunities. The Bank of Japan has maintained ultra-low interest rates (currently 0.5%) for a long time, making the yen a favorite borrowing currency—many international investors borrow low-interest yen, switch to USD investments (the USD/JPY interest rate differential is about 4.0%), and when risks rise, close positions to buy back yen. This is a traditional arbitrage trading pattern.

Practical comparison of 4 JPY exchange methods

Rather than asking which method is the best, it’s more about choosing based on your timing, budget, and expertise. Here’s an analysis of each:

Method 1: Bank counter cash exchange

Bring cash in TWD directly to a bank branch or airport counter, and you can get cash JPY immediately. The operation is simple but the cost is the highest.

Banks use the “cash selling exchange rate,” which is usually 1-2% worse than the market spot rate. As of Taiwan Bank’s rates on December 10, 2025, the cash selling rate is about 0.2060 TWD/JPY (i.e., 1 TWD = 4.85 JPY). Plus, some banks charge an additional handling fee of 100-200 TWD. Exchanging 50,000 TWD results in a cost loss of about 1,500-2,000 TWD.

However, this method has advantages: denominations are complete, staff assistance on-site, and no need to think. Suitable for elderly unfamiliar with online operations or urgent needs at the airport.

Different banks have slight variations in cash rates—Taiwan Bank 0.2060, Mega Bank 0.2062, E.SUN Bank 0.2058—up to 4 basis points difference (~10 TWD). If you have time, it pays to check multiple banks for the best rate.

Method 2: Online currency exchange account, withdrawal at counter or ATM

Using a mobile app or online banking, transfer money from your TWD account to a foreign currency account in JPY, using the “spot selling rate,” which is about 1% better than cash exchange rates. If you want cash, you can withdraw at counters or foreign currency ATMs, but this incurs additional exchange fee (usually starting at 100 TWD).

The advantage of this method is 24-hour operation, allowing you to buy in installments to average costs. If you observe TWD/JPY falling below 4.80, you can split into three times, exchanging 10,000-20,000 TWD each time, instead of all at once. The total cost for 50,000 TWD is about 500-1,000 TWD, nearly 50% cheaper than counter exchange.

The downside is you need to open a foreign currency account first, which can be somewhat cumbersome at some banks. Also, if you decide to withdraw cash later, you’ll pay an additional fee. Suitable for those with forex experience, planning to hold JPY long-term, or considering investing in JPY fixed deposits (current annual interest rate 1.5-1.8%).

Method 3: Online currency settlement, airport pickup

This is a recent bank-promoted “lazy exchange method.” No need for a foreign currency account—just fill in the currency, amount, preferred branch, and date on Taiwan Bank or Mega Bank’s official website. After the bank completes the remittance, you go to the counter with your ID and transaction notice to pick up cash.

Taiwan Bank’s “Easy Purchase” online settlement even waives handling fees (using Taiwan Pay costs only 10 TWD), with about 0.5% better exchange rate. The key is that Taoyuan Airport has 14 Taiwan Bank branches, two of which are open 24 hours. You can make an appointment a day or two before departure and pick up at the airport before your flight.

For 50,000 TWD, this method costs about 300-800 TWD, between online exchange and counter exchange, with added convenience. Suitable for travelers with plans before departure who don’t want to queue at the airport. The drawback is you must make a reservation (usually 1-3 days in advance), and pickup times are limited to bank hours, with no last-minute changes allowed.

Method 4: Foreign currency ATM withdrawal

Use a chip-enabled bank card at foreign currency ATMs to withdraw cash in JPY directly, supporting 24-hour operation. E.SUN Bank’s foreign currency ATMs allow withdrawal of up to 150,000 TWD equivalent per day from a TWD account, with a cross-bank fee of only 5 TWD, and no additional exchange fee.

It sounds very convenient, but in reality, there are only about 200 foreign currency ATMs nationwide in Taiwan, which is far less common than regular ATMs. The supported currencies are limited, usually only major ones, with fixed denominations of 1,000, 5,000, or 10,000 JPY bills. During peak times at busy airports or stations, cash may run out.

Therefore, this method is more suitable for residents near foreign currency ATM branches who want to avoid the hassle of counter exchange. Cost is about 800-1,200 TWD (for 50,000 TWD), slightly cheaper than counter exchange but not particularly advantageous.

Which method should you choose?

Based on past experience, the most cost-effective combination for a budget of 50,000 to 200,000 TWD is “online settlement + airport pickup” or “online exchange + foreign currency ATM.” The former saves on fees, the latter saves time.

Is it worthwhile to exchange JPY now?

From 4.46 at the start of the year to 4.85 now, TWD/JPY has appreciated by 8.7%. In the second half of the year, Taiwan’s currency exchange demand increased by 25%, mainly driven by the revival of travel to Japan and investors’ risk hedging needs.

However, exchange rate fluctuations remain. According to the recent hawkish comments from Bank of Japan Governor Ueda Kazuo, the market expects a 0.25 basis point rate hike at the December 19 meeting to 0.75% (a 30-year high). Japanese government bond yields have broken through 1.93% (17-year high). These signals support a short-term upward trend for the yen, but USD/JPY has fallen from 160 at the start of the year to 154.58 now, likely to fluctuate around 155 in the near term, with a medium- to long-term trend below 150.

Conclusion: It’s a good time to exchange, but don’t convert all at once.

Gradual entry is the right approach. You can buy 10,000-20,000 JPY in three installments within the 4.80-4.90 range, avoiding high points and diversifying exchange rate risk. As a safe-haven currency, short-term arbitrage positions may cause 2-5% volatility, but long-term holding still has value.

What to do after getting JPY?

Don’t let your exchanged JPY just sit idle without earning returns. Depending on your purpose and risk tolerance, consider these options:

JPY fixed deposit: The most stable choice. E.SUN Bank and Taiwan Bank offer foreign currency accounts with a minimum deposit of 10,000 JPY, annual interest rates of 1.5-1.8%. It’s like treating JPY as a low-risk financial product.

JPY insurance policies: Cathay and Fubon Life offer JPY savings insurance with guaranteed interest rates of 2-3%, suitable for medium-term holding of 3-5 years.

JPY ETFs: Want higher growth? Yuanta 00675U tracks the JPY index, or linked JPY assets like 00703, which can be bought as fractional shares via securities apps, suitable for dollar-cost averaging. Management fee is about 0.4% annually.

JPY forex trading: For experienced traders. USD/JPY or EUR/JPY rate movements often contain opportunities. You can trade intra-day or swing on forex platforms, with advantages like 24-hour trading, long/short positions, and flexible leverage.

The BOJ’s rate hikes are positive signals, but global arbitrage unwinding or geopolitical conflicts (Taiwan Strait, Middle East) may temporarily weaken the yen. For investment purposes, ETFs are recommended for diversification, while swing trading requires sufficient market knowledge.

Common questions about JPY exchange

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

Cash rate (Cash Rate) is the buy/sell rate banks offer for physical cash, payable immediately, but usually 1-2% worse than the spot rate. Spot rate (Spot Rate) is the foreign exchange market’s T+2 settlement rate, mainly used for electronic transfers, closer to international market levels, but takes two business days to settle. In short: cash is more expensive, spot is cheaper, but cash is convenient and spot requires waiting.

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

Based on Taiwan Bank’s rate on December 10, 2025, the cash selling rate is 4.85, so 10,000 TWD can buy about 48,500 JPY. Using the spot selling rate of 4.87, it’s about 48,700 JPY, a difference of roughly 200 JPY (about 40 TWD). Actual transaction depends on the bank’s quote at the time.

Q: What ID do I need to bring for counter exchange?

Taiwanese nationals: ID card + passport; foreigners: passport + residence permit. For corporate exchange, bring business registration documents. For online pre-booking, also bring transaction notice. Minors under 20 need a parent present. Large amounts (over 100,000 TWD) may require source of funds declaration.

Q: Are there limits on foreign currency ATM withdrawals?

As of October 2025, banks have adjusted limits. E.SUN Bank’s card: single transaction limit equivalent to 50,000 TWD, daily limit 150,000 TWD; Taishin Bank: single 120,000, daily 150,000. Digital accounts affected by anti-fraud regulations may have lower limits, around 100,000 TWD/day. Cross-bank withdrawals usually capped at 20,000 TWD per transaction; check with your bank for specifics. It’s recommended to diversify withdrawals or use your own bank card to avoid cross-bank fees.

Summary: Treat JPY as an asset, not just pocket money

JPY is no longer just a “travel currency” but a liquid, hedging, and investment asset class. Especially amid the TWD depreciation pressure and ongoing global geopolitical risks, holding some JPY has strategic significance.

Whether your goal is to travel to Kyoto or Hokkaido next year, or to add a layer of protection during Taiwan stock market volatility, following the principles of “gradual exchange + not leaving the position idle” can minimize costs and maximize returns.

Beginners should start with the simplest “online settlement + airport pickup,” then gradually move to online exchange accounts or forex trading as experience grows. This not only makes traveling more cost-effective but also adds a defensive layer to your assets during market turbulence. Compared to exchanging TWD for MYR or other Asian currencies, JPY’s liquidity and financial tools remain the top choice.
