Frequently asked questions
How much is 1 gram of gold in Japanese yen today?
The computed price of one gram of gold (999.9 fine) is ¥20,983 at the official JPY rate. Real-world bank or jeweller prices are higher by the dealer premium, VAT and fees.
How is this price calculated?
We take the global indicative gold price (XAU/USD) and multiply it by the official JPY rate from central-bank data (Frankfurter). It is a computed value: local dealer premiums, taxes and delivery are not included.
Why is the price at a shop or bank different?
Banks and jewellers add a premium over the market price for fabrication, logistics, VAT and their own margin, and apply a discount when buying back. The gap typically runs from 2–3% on investment bars to tens of percent on jewellery.
