Sources & Methodology
Exchange rates are mid-market rates sourced from the Exchange Rate API, which aggregates data from central banks and financial institutions. Historical data is provided by the Frankfurter API (ECB reference rates). Rates are cached for 12 hours and are for informational purposes only. Actual transaction rates from banks and services may differ.
Reference notes for JPY/GBP
When you typically see JPY/GBP
Three groups generate most of the JPY-to-GBP lookups: Japan-resident postgraduate students paying UK university tuition (single large transactions in autumn each year), Japanese SMEs subscribed to UK-billed SaaS (a smaller but more frequent flow), and Japanese travelers to London on business or for short leisure trips. The university-tuition case is by far the highest-value: a year of fees at a London-based master's program runs £30,000–£45,000, and the rate on the transfer day moves the JPY cost by tens of thousands of yen for a single percentage-point swing. London-headquartered consulting firms billing Japanese corporate clients are a steady B2B flow, usually invoiced quarterly in GBP.
How JPY/GBP behaves in accounting
Mizuho publishes GBP/JPY TTM, TTS, and TTB directly. Coverage is reliable but liquidity-thin compared to USD/JPY, which sometimes produces slightly wider TTS–TTB spreads. GBP/JPY has historically been one of the more volatile JPY crosses — moves of 1–2% intraday are not unusual around BOE meetings or UK political events. For one-off transactions like tuition payments, transaction-date TTM is the conventional record. If the company's home accounting policy is HMRC monthly average (rare in Japan, but conceivable for a Japanese subsidiary of a UK parent doing dual reporting), that source would apply on the GBP side. Note that HMRC's rate is NOT implemented in the current rate-sources directory — only the registry type ID exists.
Common conversion mistakes for JPY/GBP
Treating the swift fee on a tuition transfer as a translation gain or loss instead of as a fee line. SWIFT correspondents often charge ¥3,000–¥7,000 plus a percentage; that is a fee, not an FX delta. Using the rate at the wire-initiation moment when the bank actually executed several hours later. Mizuho and similar publish one TTM per business day; that is the right rate to record for transaction-date policy, even if the bank's internal cut quoted something slightly different. Calling the UK National Holidays calendar wrong. UK observes May Day, Spring Bank Holiday, Summer Bank Holiday — none of which Japan observes. Mizuho will publish a JPY/GBP rate anyway on those days, since Tokyo is open. Use it.
What Zenrate stores for JPY/GBP
Live conversion via exchangerate-api.com (USD-base cross-rated). Twelve-hour cache. Historical: Mizuho GBP/JPY through dbFetcher/edgeFunction. ECB GBP/JPY via Frankfurter (ECB publishes GBP as a quote against EUR; cross-rated through EUR for JPY direction). HMRC monthly-average rates: documented in the rate-source registry as type ID `hmrc` but not implemented as a fetcher in `packages/core/src/rate-sources/`. Pages requiring an HMRC rate today receive an ECB fallback. All six rate policies work. The prior-month-average policy on this pair is slightly noisier than for USD/JPY because daily moves are wider; the average smooths but does not eliminate the swing.
