JPY to KRW Converter (Japanese Yen to Korean Won)
1 JPY = 8.51004 KRW at the saved rate of 2026-11-10. Convert Japanese yen into Korean won, including the per-100-yen figure Korean banks quote.
Both currencies are written without decimals: the yen (JPY, ¥) is issued by the Bank of Japan and the won (KRW, ₩) by the Bank of Korea. In Korea the yen is quoted per 100 yen rather than per single yen, so the number on a bank rate board or in a news report is the won value of a 100-yen coin.
Yen-to-won conversions are made by Japanese visitors arriving in Seoul or Busan, by fans in Japan pricing concert tickets and albums sold in won, and by Koreans home from a trip to Japan with yen left over. Companies that bill in yen and pay staff in won, and Korean residents receiving wages or pensions from Japan, need the same figure.
How to use this tool
- Type an amount in JPY to see it in KRW, or type in the KRW box to convert the other way.
- Read the rate line under the boxes: it shows the saved rate and its date.
- Use the tables below for common amounts, or open the currency converter for any other currency.
Formula
KRW amount = JPY amount × rate
JPY amount = KRW amount ÷ rate
The rate is the value of 1 JPY in KRW from the snapshot of 2026-11-10. Both currencies are priced in US dollars in the same table, so the rate is the KRW per USD figure divided by the JPY per USD figure. A bank's buying and selling rates sit on either side of this mid-market figure.
Example
Two conversions at the saved rate:
100 JPY × 8.51004 = 851 KRW
100,000 KRW ÷ 8.51004 = 11,751 JPY

Reading the 100-yen quote
To use a Korean bank's board, take the won figure shown next to JPY (100) and divide it by 100 for one yen, or multiply it by the number of hundreds in your yen amount. The first tables on this page include a 100-yen row so you can compare directly.
A bank board usually lists several yen figures: a base rate, a rate for buying cash, a rate for selling cash and rates for transfers. When you hand over yen banknotes, the bank pays its cash buying rate, which is the lowest of these.
Quick mental estimate
Multiply JPY by 8.5 for a rough KRW figure: 1,000 JPY → about 8,500 KRW. That factor is 0.12% below the saved rate.
Rates move every day, so recheck the rate line before you rely on a shortcut.
Frequently asked questions
Can I exchange yen coins in Korea?
Many banks in Korea exchange foreign banknotes only, and where coins are accepted they are usually bought at a steep discount. Spending your 1, 5, 10, 50, 100 and 500 yen coins in Japan, for example at an airport shop, avoids that loss.
Do I have to declare yen when I enter Korea?
Only if the yen, won and other currencies or checks you carry exceed US$10,000 in total. Above that amount Korea Customs Service requires a declaration on arrival.
Where can I find an official yen-won reference rate?
The Bank of Korea's Economic Statistics System (ECOS) publishes daily won rates against the yen, quoted per 100 yen. Bank quotes for cash and transfers are set around the market rate and include a spread.
Is this the live exchange rate?
No. The page uses a snapshot of mid-market rates saved when the site was last updated, and the rate line shows its date. Your bank, card issuer or transfer service quotes its own rate, usually with a margin or fee, so the amount you actually receive will differ.
