To convert KRW to JPY, divide the won amount by the number of won it takes to buy one yen. At an indicative rate of about 9.497 won per Japanese yen (22 June 2026), 1,000,000 KRW is roughly 105,296 JPY. Enter any won amount below for a live indicative conversion that pulls the latest mid-market rate from fxkrw.com.
The formula is JPY = KRW ÷ rate, where the rate is the number of won it takes to buy one yen. Because a single Japanese yen is worth only a small fraction of a Korean won, the two currencies sit fairly close in value: roughly 9 to 10 won equals one yen, so dividing your won amount by about 9.5 gives a fast estimate. The converter above does the exact math and refreshes the indicative rate automatically.
If you have ever glanced at a Korean bank board or a news ticker, you may have seen the won-yen cross written as something like "950" rather than "9.5". That is because banks conventionally quote the Japanese yen per 100 yen for readability, since the per-single-yen number is awkwardly small. The two statements mean exactly the same thing: 100 JPY ≈ 950 KRW is identical to 1 JPY ≈ 9.497 KRW. Our converter works in single yen so the arithmetic stays transparent, but if you compare against a Korean bank screen, remember to read its figure as a price for 100 yen, not one.
Using the indicative rate of 9.497 KRW per JPY (22 June 2026):
| Korean won (KRW) | Japanese yen (JPY) |
|---|---|
| 10,000 KRW | ¥1,052.96 |
| 50,000 KRW | ¥5,264.82 |
| 100,000 KRW | ¥10,529.64 |
| 500,000 KRW | ¥52,648.20 |
| 1,000,000 KRW | ¥105,296.41 |
Japan is one of the most popular short-haul destinations for Korean travellers, and Korea is just as popular with Japanese visitors, so the won-yen cross is the rate millions of people actually live with on holiday. A weaker yen makes Tokyo, Osaka and Fukuoka noticeably cheaper for Korean tourists — hotels, ramen and shinkansen tickets all cost fewer won — while a stronger yen does the reverse. Because flights between Seoul and Japan are short and frequent, even a few percent of movement in the cross changes how far a travel budget stretches, which is why frequent flyers watch this pair more closely than the headline won-dollar rate.
The converter shows the mid-market rate — the midpoint between buy and sell prices that banks trade at. When you actually exchange money, providers add a margin: airport kiosks and traditional banks can be 2–4% worse, while specialist apps (Wise, Revolut and Korean services from banks like Hana or Woori) usually sit much closer to the mid-market figure. Cash yen exchanged at a Japanese airport on arrival tends to carry one of the widest spreads, so it pays to compare the effective rate, not just a "0 commission" sign — a poor exchange rate is itself a hidden fee.
Neither the won nor the yen is traded directly against the other in large volume; instead both are priced against the US dollar, and the KRW/JPY cross is derived from those two dollar rates. That means the pair reacts to anything that pushes USD/KRW and USD/JPY apart. The biggest drivers are monetary policy divergence between the Bank of Japan and the Bank of Korea — when the BoJ keeps rates ultra-low while the BoK holds higher, the yen tends to weaken against the won. The yen's role as a global safe-haven currency adds another layer: in times of market stress, money flows into the yen, lifting it against the won even when nothing has changed in Korea. Watch BoJ and BoK rate decisions, Japanese inflation, and global risk sentiment to anticipate where the cross is heading. The pair can move 1–2% in a day around major announcements, so the figure here is a snapshot, not a fixed promise.
Divide the Korean won amount by the number of won it takes to buy one yen. For example, at about 9.497 won per yen, 1,000,000 KRW divided by 9.497 is roughly 105,296 Japanese yen. Enter your won amount in the converter above to get the live indicative figure.
At an indicative rate of about 9.497 KRW per JPY, 1,000,000 Korean won is roughly 105,296 Japanese yen. The exact amount changes constantly with the market and the spread your bank or app applies.
Because a single yen is worth only a small fraction of a won, banks and news tickers usually quote the won-yen cross per 100 yen for readability. So 100 JPY is about 950 KRW, which is the same thing as 1 JPY being about 9.497 KRW. Our converter works in single yen so the math is exact.
No. The converter shows the mid-market (interbank) indicative rate. Banks, airport kiosks and apps add a margin, so the rate you receive is usually 0.5 to 4 percent worse depending on the provider. Use this as a benchmark, not the final price.
Both the won and the yen are priced against the US dollar, so the cross moves with US interest rates, Bank of Japan and Bank of Korea policy, and safe-haven flows into the yen. It can move 1 to 2 percent in a single day, which is why the converter pulls a fresh indicative rate.
