Date-specific lookupJPY workflow
When the yen moves sharply: use KRW/JPY data by task
A sharp yen move changes the number used in a document, but it does not change the document date. Use the KRW/JPY observation that matches the invoice, payment, month-end, or travel-budget task, then keep the date and source URL with the record.
Month-end close or revaluation
Use the selected month-end or monthly-average KRW/JPY view and save the CSV with the close file.
Open the workflowJPY import cost or payout
Compare the dated KRW/JPY rows before and after the move, then put the source URL in the reconciliation note.
Open the workflowJapan travel budget
Convert the planned amount and compare the 30-day range shown on this page; treat it as a reference estimate, not a guaranteed quote.
Open the workflowExcel, Sheets, or dashboard tracking
Use the KRW/JPY CSV or JSON endpoint so the observation date stays attached to each row.

How to use this KRW/JPY reference
This page combines the latest KRW/JPY reference rate with 255 daily observations so you can check a figure, compare a period, or explain a conversion without turning the page into a forecast. The high, low, and average markers describe the observed window in this dataset, not a prediction of future movement.
For an invoice, receipt, payout, or accounting record, use the exact available rate for the relevant business date and keep the pair, source URL, and retrieval path beside it. FXpeek provides reference data for lookup, reporting, spreadsheets, and lightweight API workflows. It is not a bank, card, broker, remittance, or settlement quote, and nothing here is financial advice.
FXpeek sources KRW/JPY reference rates from public reference-rate data and refreshes the historical table daily, so the page always labels the latest available date. For a precise record, confirm the observation date on the row or graph before quoting the value, and use the date-specific lookup when the exact business day matters.

Which FXpeek rate should you use?
KRW/JPY FAQ
What is the latest available KRW to JPY reference rate?
FXpeek shows 1 KRW = 0.1159 JPY as the latest available reference rate; it is not a transaction or settlement rate.
How do I get historical KRW/JPY rates for accounting records?
Use date-specific lookup or the CSV/API endpoint, then keep the date, pair, and source URL with the record.
Can I export KRW/JPY history as CSV?
Yes. FXpeek provides CSV and JSON API examples for supported currency pairs.
What source does FXpeek use for KRW/JPY?
FXpeek uses public reference-rate sources and data-backed historical tables.
Does FXpeek update the KRW/JPY rate daily?
FXpeek refreshes historical reference data daily and labels the latest available date on the page, so you can tell how current the observation is.
Can I use this KRW/JPY rate for tax or legal records?
The rate is reference data, not advice. For tax, legal, or settlement records, use the rate from the relevant business date and keep the source URL with the record.
How do I convert an amount of KRW to JPY?
Use the converter on this page or the common amount table, which shows how a fixed KRW amount converts at the latest available reference rate. For a dated figure, use the date-specific lookup instead.
Does FXpeek charge for the KRW/JPY CSV or API?

Use the rate for the invoice, payment, report, or other documented date. A recent yen move is not a reason to replace a historical document date with today's reference rate.
