Department-store jewellery sales are up a fifth, and the gold price explains most of it

Japan's department stores sold ¥57.5bn of art, jewellery and precious metals in July, 16.7% more than a year earlier on a like-for-like store basis, according to the Japan Department Stores Association's monthly report published on 25 August, which floortok covered on the day. It was the seventh consecutive month of growth above 16% for the line: 17.7% in January, 18.0% in February, 20.8% in March, 19.6% in April and again in May, 22.3% in June and 16.7% in July. No other product line in the association's table comes close. Clothing grew 3.9% in July, food 0.2%, and gift vouchers fell 7.2%.

The line matters more than its 11.8% share of July sales suggests, because it is where the growth is. Department-store sales rose 5.1% in July on the association's count, to ¥488.9bn; on our arithmetic from the association's figures, roughly two-fifths of the store's entire year-on-year gain came from jewellery, watches and precious metals, a counter that a year earlier held 10.6% of takings. The association's own commentary names the customers: in July it described high-priced watches selling on scarcity and their standing as assets, led by gaisho (the outside-sales teams that serve wealthy account customers) and affluent domestic buyers, and in June it credited the same buyers' appetite, backed by a rising stock market, with weak-yen inbound demand on top.

The metal did most of the work

Before reading that as a wave of new customers, look at what the goods on the counter cost. The World Bank's monthly average gold price was $4,073 an ounce in July, 21.9% above July 2025, and $4,411 in August, 31.0% higher. In yen the move is larger, because the currency weakened at the same time: at the Federal Reserve's monthly average of ¥162.33 to the dollar, an ounce of gold cost about ¥661,000 in July, 34.5% more than a year earlier, and about ¥701,000 in August, 41% more. Silver was up 56% in dollars in July and platinum 17%. Gold in yen had been rising even faster earlier in the year, by 76% in January and 62% in April, which is when the department-store line was posting its 18% to 20% months.

The association's line bundles finished jewellery and watches with bullion and coins sold over the precious-metals counter, so part of it reprices with the spot market month by month, and the rest reprices when the houses move their lists. Against a metal up a third to three-quarters in yen, a sales line up a fifth is consistent with flat or falling unit volumes. The ticket data the association publishes for its tax-free counters points the same way: in July it reported spend per tax-free purchaser about a fifth higher than a year earlier, while in June the number of tax-free purchasers slipped 0.5%. In May it attributed the rise in spend per visitor to the weak yen and to price increases on high-priced goods, in its own words rather than ours.

Customs data says the same thing from the supply side. Imports of Swiss watches were ¥45.2bn in July, 24.5% more than a year earlier, and reached ¥55.7bn in March, the highest month in the customs series floortok tracks; but the franc bought ¥200.31 in July against ¥184 a year earlier, so in the currency the houses invoice in the rise is nearer 14%. Jewellery imports under the precious-metal heading were ¥384.7bn over January to July, up 15% on the same months of 2025, in a series that swings by tens of billions from one month to the next. The value series floortok tracks do not separate units from price, which is the honest limit of the argument: what can be said is that the value of what arrives, the value of what sells and the price of what it is made of are all rising, and the last is rising fastest.

What the store gives up

This is where the inflation reading matters for the rest of the building. If the jewellery counter's growth is mostly price, the customers paying it are not necessarily more numerous or more active; they are paying more for the same object, and for the domestic buyer that money is coming out of a household budget that did not grow a fifth. The rest of the association's July table reads like the other side of that ledger: food up 0.2%, restaurants up 0.8%, furniture up 0.2%, other sundries down 1.1%, vouchers down 7.2%. The share of sales taken by the priciest counter rose by more than a point in a year, and the share taken by the counters that draw everyday traffic fell. A store can report 5% growth on that mix while its footfall does not move; the association's own July survey of a hundred stores found 52 with more customers, 29 with fewer and 19 flat.

For a maison the lever here is Product and price rather than People: the counter is selling fewer, dearer things to the same account customers, and to visitors whose yen go further. For a department store the question is what the traffic floors get in return, because a jewellery boom that is mostly metal price does not fill the food hall. Two dates will tell. The association's August report on 25 September will show whether the line held above 16% against a base that was itself already rising, and the September gold average, which the World Bank publishes in early October, will say how much of that was the metal again. If gold flattens and the counter keeps growing, there are new buyers; if both slow together, there never were.
