Silver price per grain in JPY today

Definition. The grain (0.0648 g) is the smallest troy unit, one 480th of a troy ounce. One grain equals 0.0648 grams, or 0.00208 troy ounces, which at today's silver spot price works out to — JPY.

Where it is used. Historical coin weights, gold leaf and very small assay samples are still specified in grains. The unit is the trading standard in coin collecting and assaying.

Pricing conventions. No modern bullion product is sold by the grain, but numismatic catalogues use it, so collectors convert grain weights when valuing old coinage. Silver is bulkier per unit of value, so quotes in small traditional units are usually a conversion, while real trade happens in kilogram and 1 000 oz bars.

Good to know. The grain was originally the weight of a single barley seed, making it one of the oldest surviving mass units in use.

At the live price shown above per grain, the price you see here is the international XAG spot price converted into Japanese Yen. Physical buyers in Japan pay that reference plus a premium, and local trading is concentrated around Tokyo, where Tanaka Kikinzoku and Mitsubishi Materials set retail quotes. Buyers there generally watch the domestic per-gram retail price published each morning by the major refiners as the day's reference.

Taxes and duties. Silver, platinum and palladium are also sold with 10% consumption tax; Japan is one of the deepest retail platinum markets in the world. Silver is bulkier and cheaper per unit, so shipping, storage and consumption taxes matter far more to the final price than they do for gold. That is why the shop price of silver in JPY can sit noticeably above the spot value of the same grain of metal.

How people usually buy. The common routes in Japan are Tanaka Kikinzoku shops, department-store precious metal counters, monthly gold accumulation plans (junkin tsumitate) and TOCOM futures. The products most often quoted locally include 500 g and 1 kg Tanaka bars, platinum bars, momme-weight jewellery.

Local conventions. Traditional weights such as the momme (3.75 g) are still used for pearls and some jewellery, while bullion is quoted per gram. Before you buy, compare the dealer's asking price per grain with the live silver price above, and check the buy-back spread the same dealer offers — that round-trip cost matters more than a small difference in the headline JPY quote.
