Smart Currency Exchange in Seoul: JPY to KRW Tips 2026

Understanding the JPY/KRW Rate in August 2026

If you are traveling from Japan to South Korea — or sending money between the two countries — the exchange rate between the Japanese yen (JPY) and the South Korean won (KRW) is something worth watching closely. Over the 22-day window from July 8 to August 7, 2026, the JPY/KRW rate started at 9.2874, climbed to a high of 9.3124, and then fell to a low of 8.7989 before closing at 9.0195. That is a swing of roughly -2.88% across the period, with an average rate of 9.08169 KRW per JPY.

In practical terms, this volatility means that the timing of your exchange genuinely matters. Someone who exchanged 100,000 JPY at the period high would have received approximately 931,240 KRW, while the same amount exchanged near the low would have yielded only around 879,890 KRW — a difference of over 51,000 KRW, or roughly the cost of a decent Seoul restaurant meal for two.

Where to Exchange Money in Seoul

Seoul offers several options for currency exchange, each with different costs and convenience trade-offs.

Airport kiosks (at Incheon or Gimpo) are the most convenient but typically offer the least favorable rates. The spread — the gap between the buy and sell price — tends to be wider here because operators factor in higher overhead and captive foot traffic.

Myeongdong money changers are a well-known alternative. The dense cluster of independent exchange booths in central Seoul competes aggressively for business, and rates here are often very close to the mid-market rate (the midpoint between buy and sell prices, with no markup added). Bring cash JPY and compare a few windows before committing.

ATMs are convenient for withdrawing KRW directly, but not all ATMs are equal. Global ATM networks like Cirrus or Plus work well, and machines labeled "Global ATM" in convenience stores such as GS25 or CU are generally reliable. Watch out for two fees:

1. Your home bank's international withdrawal fee (often a flat fee plus a percentage)
2. Dynamic currency conversion (DCC) — when the ATM offers to charge you in JPY instead of KRW, always decline. DCC rates can cost you 3–5% more than simply letting your bank handle the conversion.

Wise and Revolut: Are They Worth It?

Financial apps like Wise and Revolut have become popular tools for travelers and small businesses managing multi-currency expenses. Both are worth understanding objectively.

Wise (formerly TransferWise) converts at the mid-market rate and charges a transparent, low percentage fee — typically around 0.4–1.5% depending on the currency pair, though you should verify current fees on their website before travel. For JPY-to-KRW conversions, this can meaningfully beat high-street bank rates.

Revolut offers a multi-currency account where you can hold KRW, JPY, and other currencies simultaneously. On standard plans, there is a fair usage limit for fee-free currency exchange; exceeding it, or exchanging on weekends when interbank markets are closed, may trigger a markup of around 0.5–1%.

Neither app is a guaranteed "best" option in every scenario — the right choice depends on your transaction size, frequency, and whether you are converting in advance or at the point of sale. Both work well alongside a mid-market rate tracker so you can judge the rate you are actually being offered.

Tracking Costs for Business Travelers and Expense Reports

For business travelers and small businesses, currency exchange is not just a matter of convenience — it feeds directly into expense reporting and accounting. The average rate of 9.08169 KRW per JPY (or equivalently, 0.110112 JPY per KRW on average, with the latest rate at 0.110871 JPY per KRW) during this period is the kind of reference figure that finance teams need to reconcile receipts.

Best practices for expense reporting in multi-currency contexts include:

• Record the rate at the time of transaction, not the end-of-month rate. Many accounting standards require this.
• Keep receipts that show both the local KRW amount and the foreign-currency equivalent.
• Use a single consistent rate source across your team to avoid discrepancies — central bank reference rates are commonly accepted benchmarks.
