The weak yen has turned Japan into the world's discount luxury store

The dollar bought ¥146.29 in January 2024. By June 2026 it bought ¥160.77, an 11% weaker reading than a year earlier, according to the U.S. Federal Reserve's monthly exchange-rate data. The slide has continued since: the Bank of Japan's own daily quotation put the central rate at ¥163.80 on 28 July. Every extra yen of depreciation is a fresh discount, in dollar or euro terms, on a handbag or a watch priced in yen on a Ginza shelf.

Department-store sales are the clearest place to see that discount being spent. Nationwide department-store sales reached ¥513.7 billion in May 2026, up 7.6% year on year, the fastest monthly gain since June 2024, according to METI's Current Survey of Commerce. The pace has been accelerating steadily, from just 1.6% in February to 2.3% in March, 4.5% in April and 7.6% in May. Duty-free and tax-free counters, the retail floor most directly exposed to foreign wallets, are the obvious place that growth is concentrated.

But the tourist headcount itself has stopped climbing

The chain the numbers are supposed to prove, a weaker yen pulling in ever more visitors, has a hole in it. Japan's foreign arrivals actually fell 6.8% year on year in June 2026, to 3.15 million, according to the Japan National Tourism Organization (JNTO), and the first half of 2026 (21.08 million arrivals) ran slightly behind the same period of 2025. JNTO points to thinner flight schedules and typhoon disruption in some markets; even so, 15 individual source markets, including Taiwan, South Korea, Vietnam, India, Australia and the United States, set their own all-time June highs.

What that split suggests is that headcount is no longer doing the work on its own. The Japan Tourism Agency's own inbound consumption survey put shopping spend at ¥589.5 billion in the first quarter of 2026, a quarter of everything foreign visitors spend in the country and more than double the ¥241.7 billion recorded in the same quarter three years earlier. With arrivals no longer rising in lockstep, that growth increasingly looks like a story of fewer, higher-spending trips rather than simply more of them.

Price, product and place are all pointing the same way

The mechanism is a straightforward pricing arbitrage: a bag or a watch priced in yen gets cheaper every month in dollar, euro or won terms, without a Japanese retailer changing a price tag. Maisons respond on the product side by prioritising allocation to Japan flagships while the market is compounding this fast. The property market is pricing in the same durability rather than treating it as a blip: Ginza's benchmark commercial land value hit ¥67.1 million per square metre at the start of 2026, up 10.9% on the year and the 20th consecutive year atop Japan's national ranking, according to the land ministry's published land-price survey.

The practical read for anyone running a Japan floor is that footfall is no longer the reliable proxy it once was. With the raw number of visitors flat to falling even as the yen keeps sliding, the swing factor becomes what each visitor is persuaded to spend once they are through the door, a dynamic that rewards clienteling, curated allocation and full-price sell-through over simply counting heads at the entrance. A further leg down in the yen would only sharpen it.

The discount runs deeper in euros and yuan

The dollar is only part of the story. The yen has fallen even faster against the euro and the Chinese yuan than against the dollar, so the discount is deeper still for European and Chinese shoppers. On the Federal Reserve's monthly averages, since January 2024 the euro has gone from buying ¥159 to ¥185 and the yuan from ¥20.4 to ¥23.7 — gains of about 16% each — against roughly 10% for the dollar (¥146 to ¥161). In plain terms, the same ¥100,000 handbag that cost a European shopper about €627 in early 2024 now costs roughly €540, about 14% cheaper, with a near-identical saving in yuan — versus a 9% discount for an American paying in dollars.

That is why the nationality on the shop floor now matters as much as the yen on the screen. As the euro and yuan stretch further than the dollar, the visitors carrying them — and the maisons and floors that court them — capture the deepest discount Japan has offered in a generation.
