How the gold price in Japan is calculated
We take the live spot price of 4,120.40 USD per troy ounce, divide it by 31.1035 to get 132.47 USD per gram of pure gold, and multiply by today’s exchange rate of 158.3779 JPY per dollar. That gives 20,980.94 JPY per gram for 24K. Lower karats are priced by their gold content.
Japanese retailers such as Tanaka publish daily retail gold prices in yen per gram that include consumption tax.
Before you sell, weigh your pieces on a jeweler’s scale, check the hallmark and compare at least two quotes. Read our guide to selling gold.
