What moves the JPY/KRW rate
The yen's value leans heavily on the Bank of Japan's policy and the interest-rate gap between Japan, Korea, and the US. When Japan holds rates low, the yen tends to soften — the "weak yen" that makes trips and imports cheaper for Korean shoppers; when global markets turn jittery, the yen can strengthen as a safe haven. On the won side, Korea's exports, the dollar's level, and foreign capital flows all pull at the number. Add peak-season travel demand and the won value of 100 yen can shift several times a day, so it pays to check the latest figure right before you exchange or buy.
Reading the number — 1 yen vs 100 yen
A single yen is a tiny amount, so people usually gauge yen prices "per 100 yen." This converter shows the per-1-yen value (say, 1 JPY ≈ 9 KRW), but since real price tags come in hundreds and thousands of yen, you just multiply straight through. If one yen is 9 won, a ¥100 convenience-store coffee is about 900 won and a ¥500 souvenir is roughly 4,500 won. A quick trick: multiply the number after the ¥ sign by about 9 for an instant won estimate, then use the converter below for the exact figure.
Live mid-market rate vs what you'll actually pay
This tool uses the mid rate published by the Export-Import Bank of Korea (Korea Eximbank). The mid-market rate is the reference price banks trade at with each other — the same "exchange rate" you see quoted in the news. Real transactions differ: bank exchanges, card payments abroad, and remittances add a spread plus fees, so you pay a little more than the mid-market figure. A ¥30,000 hotel bill is about 270,000 won at mid-market, but a card charge with fees will run slightly higher. Treat this number as a solid budgeting benchmark, and confirm the final amount with your bank's or card issuer's posted rate.
Frequently asked questions
Why is my bank's exchange amount different from this figure?
This converter shows the mid-market rate — the bank-to-bank benchmark. Exchange counters and banks add a spread over that base (often around 1.5–1.75% when you buy yen cash) plus any handling fee, so you hand over a bit more won for the same yen; when you sell yen back, you get a bit less. Use this value to plan your budget, then check the bank's posted rate just before you actually exchange.
How do I quickly see the value of 100 yen?
Type 100 into the converter and it shows the won value of 100 yen right away. For mental math, take the per-1-yen value (say 9 won) and multiply by 100; for a ¥3,500 item, 3,500 × 9 ≈ 31,500 won. Since yen price tags usually come in 100- and 1,000-yen steps, this is the handiest way to think while traveling or shopping.
How often does the rate update — is it accurate on weekends?
Rates come from the Export-Import Bank of Korea's base rate, published once per business day at around 11 a.m. Korea time (weekends and holidays keep the previous business day's value). That means weekends and holidays keep the previous business day's value, and intraday tick-by-tick moves aren't captured. For large exchanges or transfers, cross-check your bank's live rate at the moment you trade.
