Recently, many people have been asking me how to exchange Japanese Yen at the most cost-effective rate, so I’ve organized my insights to share with everyone. Honestly, many think that exchanging Yen just involves going directly to a bank counter, but they don’t realize that the exchange rate difference alone can cost you the price of several bubble teas.

First, let’s talk about why you should exchange Yen. On the surface, it’s because everyone loves traveling to Japan, but in fact, the Yen is more than just pocket money for tourism. From an investment perspective, the Yen is one of the three major safe-haven currencies globally, alongside the US dollar and Swiss franc. During last year’s Russia-Ukraine conflict, the Yen appreciated by 8% in a week, demonstrating its safe-haven role. For Taiwanese investors, holding some Yen adds an extra layer of protection against fluctuations in the Taiwan stock market.

Is now a good time to exchange Yen? My answer is: yes, but in installments. At the end of last year, the TWD/JPY exchange rate was about 4.85, up 8.7% from 4.46 at the start of the year, which is already a good gain. The Bank of Japan is on the verge of raising interest rates, Japanese government bonds are yielding higher, and USD/JPY has fallen from a high of around 160 at the start of the year to about 154. Short-term fluctuations are possible, but in the medium to long term, it should trend below 150. So instead of exchanging all at once, it’s better to buy in parts to average the cost.

Regarding methods of currency exchange, I’ve summarized four most practical options:

**First** is the traditional over-the-counter exchange, where you bring cash TWD to a bank or airport to buy Yen notes. The advantage is safety, reliability, and full denominations. The downside is that you’re using the “selling cash rate,” which is 1-2% worse than the spot rate, plus possible service fees, making it the most expensive option. I only recommend this as a backup or for urgent needs.

**Second** is online currency exchange with in-person withdrawal, where you use a bank app or online banking to convert TWD into Yen in a foreign currency account. This offers better rates, using the “spot selling rate.” If you want cash, you can withdraw at a counter or foreign currency ATM, but there will be additional fees. This method suits those with forex experience who want to buy in installments, and it’s also a way to invest in Yen deposits, which currently have annual interest rates of about 1.5-1.8%.

**Third** is online currency settlement with in-person pickup, which I highly recommend. You don’t need a foreign currency account—just fill out the info on the bank’s website, complete the transfer, and then bring your ID and transaction notice to pick up the Yen at the counter. Taiwan Bank’s “Easy Purchase” online settlement even waives the handling fee, and the exchange rate is favorable. The key benefit is that you can make an appointment to pick up at the airport branch—Taoyuan Airport has 14 Taiwan Bank locations, including 2 open 24 hours—making it super convenient to withdraw before your trip.

**Fourth** is foreign currency ATM withdrawal, using a chip-enabled debit card to withdraw 24/7, with only NT$5 fee for interbank transactions. The downside is limited locations, fixed denominations (1,000, 5,000, 10k Yen), and cash shortages during peak times. I advise not waiting until the last minute, especially in busy places like airports.

Regarding what to bring when exchanging Yen, many people overlook this. For over-the-counter foreign currency cash transactions, you must bring your ID and passport. If you’ve booked online, also bring the transaction notice. Minors under 20 need a parent’s accompaniment and signed consent. For large exchanges over NT$100k, you may need to declare the source of funds. Foreigners must bring their passport and residence permit.

After exchanging Yen, don’t let your money sit idle without interest. Consider a few options: Yen fixed deposits are the safest, starting from just 10,000 Yen with an annual rate of 1.5-1.8%. If you want more growth potential, look at Yen ETFs, like Yuanta 00675U tracking the Yen index, with only 0.4% annual management fee, which you can buy as fractional shares via brokerage apps for dollar-cost averaging. Another option is to trade forex swings, like USD/JPY or EUR/JPY, which is suitable for those interested in currency fluctuations.

Finally, my two main principles are: “divide your exchange into installments” and “don’t leave your money idle after exchanging.” Beginners can start with Taiwan Bank’s online settlement plus airport pickup, or use foreign currency ATMs, then transfer Yen into fixed deposits or ETFs based on their needs. This way, you not only save money on travel but also add a layer of protection during global market volatility.
