Interpretation guide
JPY100/KRW: how strong is the won against the yen?
This rate shows how many Korean won it takes to buy 100 Japanese yen. As a cross rate derived from USD/KRW and USD/JPY, it condenses the relative strength of the two currencies into one number. It matters for travel budgets and yen deposits, but also for the price competitiveness of Korean exporters that compete head-to-head with Japanese firms.
What drives the number
Direct yen-won trading is thin, so the rate effectively equals dollar-won divided by dollar-yen. Any move should therefore be decomposed into a won leg and a yen leg before drawing conclusions.
- A falling rate means the yen is getting cheaper in won terms — favorable for Japan travel and yen-asset purchases.
- A jump in USD/JPY (yen weakness) drags this rate down even when the won itself is stable.
- Bank of Japan policy shifts and the US-Japan rate gap are the dominant drivers.
The link to Korean exporters
Autos, machinery, and steel compete directly with Japanese rivals in global markets, so their margins are sensitive to this cross rate. A persistently cheap yen improves Japanese price competitiveness at Korean exporters' expense.
- When the rate sits at multi-year lows, be conservative on earnings for Japan-competing export sectors.
- A reversal from extreme yen weakness can restore the relative appeal of those pressured sectors.
- Yen-carry unwinds tend to pair a spiking JPY/KRW with global risk-off, so it doubles as a stress signal.
Personal finance uses and misreads
Buying yen only because the rate looks historically low ignores why it is low. The gap usually closes only when the US-Japan rate differential or BOJ stance changes, and the timing is hard to call.
- Historic lows can persist for years; size yen positions so you can wait.
- The usual trigger for a rebound is a BOJ policy turn, so track its meeting schedule alongside this chart.
- On TapeFlow, compare with USD/JPY and USD/KRW to tell yen-driven moves from won-driven ones.
