Japan Gold Price Calculator
Value by weight, karat, premium & discount
There is no separate "Japan gold price" set locally — gold trades on a single global market, quoted in US dollars per troy ounce (XAU/USD). The JPY prices on this site are that international benchmark converted at the live USD/JPY exchange rate, then broken down per gram and per purity. Two forces therefore move the local price: the world gold price and the Japanese Yen exchange rate.
Prices refresh automatically throughout the trading day from live market data — the page updates itself roughly every minute while open. The rates shown are spot-derived metal values: what the gold content itself is worth. Retail shops in Japan quote around this benchmark, adding a margin and workmanship when selling and deducting a spread when buying back.
24 karat gold is pure gold — 999 fineness, or at least 99.9% gold content. It is the benchmark purity for bullion bars, investment coins and gold savings accounts, and the price from which every lower karat is calculated.
22 karat gold contains 22 parts gold and 2 parts alloy metals, making it about 91.6% pure. The alloy makes it harder than 24K, which is why 22K is the standard for traditional gold jewellery in many countries.
916 is the fineness marking for 22K gold — 916 parts of gold per 1,000 parts of metal. A 916 hallmark and a 22K label describe exactly the same purity; only the notation differs.
The international spot price in US dollars per troy ounce is converted to Japanese Yen at the live USD/JPY exchange rate. Dividing by 31.1034768 gives the pure-gold price per gram, and multiplying by the purity fraction (karat ÷ 24) gives each karat's rate.
This site shows the metal value of gold based on the live spot price. Jewellers add workmanship or making charges, brand premiums, retail margins and taxes when selling, and deduct a spread when buying back — so shop prices sit above the spot-derived rate.
Gold trades continuously on global markets, reacting to interest rates, inflation expectations, central bank activity, currency moves and geopolitical events. On top of that, the JPY price also moves whenever the USD/JPY exchange rate changes — even if gold itself is flat.
Prices refresh automatically about once a minute while the page is open, using live spot market and foreign exchange data. The last update time is shown at the top of every page.
The rates track the international interbank spot price and live exchange rates closely, making them a reliable benchmark. Actual dealer quotes will differ slightly because every dealer applies its own buy/sell spread.
