Gold has been quoted per troy ounce since the era of the London gold market, and the convention stuck: COMEX futures, the LBMA benchmark, and spot FX-style XAU/USD quotes are all per troy ounce. A troy ounce weighs 31.1034768 grams — about 10% heavier than the common (avoirdupois) ounce of 28.35 grams used for everyday goods. When you see a headline gold price, it is almost always USD per troy ounce.
The XAU/JPY rate on this page is the international USD ounce price converted at the live USD/JPY exchange rate. That means the JPY ounce price can move even when gold itself is flat, purely because the exchange rate moved.
Japan quotes gold in yen per gram — major houses such as Tanaka Kikinzoku publish a daily retail reference price, and gold futures trade on the Osaka Exchange. The yen price follows the USD spot price converted at the USD/JPY rate, so a weaker yen lifts the local price.
The live gold price per troy ounce in JPY is displayed at the top of this page. It is the international XAU/USD spot price converted at the current USD/JPY exchange rate and updates throughout the trading day.
One troy ounce equals exactly 31.1034768 grams. This is heavier than the standard avoirdupois ounce (28.3495 grams) — precious metals always use troy ounces.
Because the JPY ounce price has two inputs: the USD gold price and the USD/JPY exchange rate. If the Japanese Yen weakens against the dollar, the local ounce price rises even with gold unchanged — and vice versa.
Most retail gold in Japan is sold by the gram, while the ounce is mainly a quoting convention for markets and bullion products such as 1 oz coins and bars. Use the per-gram page to see today's gram rates.
