Adidas Forum 84 High in Japan’s Pepsi Bottle Cap Series, Explained

Adidas Forum 84 High Sneaker Bottle Cap Figure No.15

What Is a Bottle Cap Figure?

Japan has a long tradition of small collectible toys bundled with food and drink products — a category broadly known as shokugan (food toys). One popular variation of this format is the bottle cap figure: a miniature sculpt designed to clip onto the neck of a Pepsi plastic bottle or can. Rather than a single generic prize, each piece in a series carries a number, encouraging buyers to hunt down every entry until the set is complete. This figure is No.15 in its series, which means there are more out there — and collectors know it.

The item is the product of a licensed collaboration between Pepsi Japan and Adidas. A blue ribbed plastic base — the part that actually snaps onto a bottle cap — holds a small but detailed miniature of an Adidas sneaker. These Pepsi bottle cap campaigns were especially prominent in Japan from the late 1990s through the early-to-mid 2000s, when brands ranging from anime studios to sportswear companies partnered with Pepsi on numbered promotional collectible runs. The exact campaign name and the full number of pieces in this particular series have not been confirmed from available sources, but the numbered structure is consistent with how these campaigns were typically designed.

The Shoe Behind the Miniature: Adidas Forum 84 High

The sneaker recreated here is the Adidas Forum 84 High, one of the most recognizable silhouettes in the brand’s basketball lineage. Adidas developed the Forum in 1984 — the same year as the Los Angeles Olympics, which informed its design ambitions — and it became an instantly identifiable shape thanks to its bold ankle strap, voluminous high-top profile, and three stripes running cleanly along the side panel. The trefoil logo rounds out the classic look.

Through the late 1980s and into the 1990s, the Forum found a second life beyond the basketball court, becoming a fixture in hip-hop and street culture across the United States and Europe. That cultural weight helped the silhouette endure, and Adidas has reissued it multiple times over the decades. The “Forum 84 High” name refers to one of those revival variants, preserving the original’s proportions and design language. The colorway on this miniature — red body with white three-stripe detailing, white trefoil logo, white laces, and a white sole — is consistent with colorways produced in the Forum’s real-world lineup.

Two Collector Worlds Meeting in One Small Object

Part of what makes this figure compelling to collectors outside Japan is the overlap of audiences it speaks to. For sneaker enthusiasts, the Forum 84 High is a well-established classic, and a piece of officially licensed Adidas merchandise connected to it carries its own significance. For collectors of Japanese promotional toys and shokugan, the bottle cap figure format — with its numbered series structure, distinctive ribbed base, and campaign-exclusive nature — fits squarely into a tradition they already know well.

Because these figures were distributed as promotional goods within Japan’s domestic market, they were never sold through normal retail channels abroad, making them largely unavailable to international buyers through ordinary means. The manufacturer of the figures has not been confirmed from currently available sources, though comparable Pepsi Japan bottle cap campaigns of the same era involved well-known Japanese toy companies. What is clear is that this piece carries three overlapping attributes — Japan-exclusive distribution, official Adidas licensing, and the numbered-series format that invites completion — that collectively define a particular kind of Japanese collectible with crossover appeal.
