We sell the adidas Japan at West Coast Deals, so I've had pairs in hand. This review answers the question people ask most: do the adidas Japan run true to size? Then it covers the construction, the history, how it compares to the Samba and Gazelle, and who it's for.
Short version: the Japan runs true to size, but it is a genuinely slim, narrow shoe. If you have wide or high-volume feet, size up half.

The short answer on sizing
The Japan runs true to size, and that's where most people should start. Be clear-eyed about the shape, though: it's built on the slim City Series last and it's narrow through the forefoot, and the nylon-and-leather upper doesn't stretch much. So: true to size, and half a size up if you have wide or high-volume feet.

How they fit
I wear a US 11 with a wider-than-average foot, and the Japan is one where my width is the deciding factor, the slim, track-bred last is narrow through the toe, so I'd lean to a half size up for genuine comfort, where someone with a slim foot would be perfect at true to size. The nylon-and-leather upper doesn't stretch much, so don't count on break-in to add width.
One of the more distinctive versions is the women's tiger-print Japan (KI6545), a leather upper with a pony hair finish in Yellow / Core Black / Crew Yellow, with the same double-stitched T-toe and serrated 3-Stripes as the rest of the line. It's listed in US women's sizing and fits true to size; on adidas, women's to men's is one full size down (a women's 8.5 is a men's 7.5). More from our TikTok:

What the adidas Japan is
The Japan was originally built for the 1964 Tokyo Olympics, part of adidas's elite running shoes of that era, and reached the public in the early 1970s. The original was a high-spec track shoe in kangaroo leather, white with red accents like the Japanese flag, and one of the most advanced running shoes of its time. It was revived in adidas's City Series reissue wave and again in updated versions, and today it's worn as a slim lifestyle sneaker rather than a performance shoe.
Are the adidas Japan narrow?
Yes, this is the key thing to know. The Japan is one of the leaner adidas retro silhouettes, with a slim last and a narrow toe box, true to its track heritage. Slim and standard feet love that snug, locked-in feel; wide feet should go up half a size or look at a roomier model like the Gazelle.
Is the adidas Japan the same as Country Japan?
No, they're related but distinct. The Japan OG is the slim, perforated runner described here. Country Japan is a separate variant in the Japan family built with supple leather and a gum sole. If you're comparing listings, treat them as different shoes.
Specs and construction
- Upper: The OG used kangaroo leather; modern versions use perforated leather or suede uppers, and textured finishes like pony hair on colorways such as the tiger print (varies by drop).
- Toe: Distinctive double-stitched T-toe.
- 3-Stripes: Serrated 3-Stripes.
- Sole: Slim, low-profile sole, gum-colored on several versions.
- Profile: Very slim and streamlined, with a narrow toe.
How it compares to other adidas models
Japan vs Tokyo. Both City Series cousins sharing the T-toe and serrated stripes. The Japan is the more archival track-runner (perforated, and it reads slightly slimmer); the Tokyo is the more casual suede sibling. Both run true to size, with half a size up for wide or high-volume feet.
Japan vs Samba. Two different corners of the archive: the Japan is the slim City Series track runner, the Samba the leather football trainer with an almond toe. Both run narrow through the forefoot, but they size differently: the Samba is the one standard and narrow feet size down half in. See our Samba sizing guide.
Japan vs Gazelle. The Gazelle has a rounder toe and more give; the Japan is slimmer and snugger up front. Wide feet do better in the Gazelle.
Japan vs SL 72. Both '70s runners, but they size differently. The SL 72 runs long and is the narrowest model we rank, so slim feet go half down while average and wide feet stay true to size. The Japan runs true to size, with half a size up for wide or high-volume feet. See our SL 72 sizing guide.
Who the adidas Japan is for
It's a great pick if you want a minimal, archival retro runner, you like a slim, locked-in fit, and you have a standard-to-narrow foot. Look elsewhere if you have wide feet or want a chunkier, more cushioned everyday shoe.
Final verdict
The adidas Japan is one of the cleanest retro runners adidas makes, and the slim profile is the whole appeal, just size with the narrowness in mind. True to size, and half a size up if you have wide or high-volume feet.
