When Maserati Indy Appeared on a Japanese Bottle Cap

A Vintage Japanese Crown Cap Featuring the Maserati Indy

A Bottle Cap with an Italian Pedigree

This is a metal crown cap — the standard-size steel bottle cap once used to seal glass beverage bottles — produced in Japan, most likely during the late 1970s. Its printed face carries a colorful illustration of the Maserati Indy, with katakana text identifying the car and its country of origin: “Italia.” The reverse is a faded gold, consistent with the liner coating typical of bottled drink caps from the period.

The cap is listed in the Coca-Cola / Bottle Caps category on eBay, though no Coca-Cola branding is visible on the item itself. The issuing beverage company — whether a Coca-Cola bottler, a Pepsi bottler, or a domestic Japanese drink maker — has not been confirmed from available evidence. Likewise, the specific themed series this cap belongs to cannot be pinned down with certainty, though several parallel series featuring European sports cars are known to have circulated in Japan during this era.

The Maserati Indy: Italy’s Understated Grand Tourer

The Maserati Indy was a grand touring car produced by the Italian manufacturer between 1969 and 1975. Its body was designed by Vignale and styled by Giovanni Michelotti, and it came with either a 4.2-liter or 4.7-liter V8 engine. Across all variants, only around 1,136 units were ever built — a modest figure even among the exotic Italian cars of its generation.

The name “Indy” connects the car to one of Maserati’s proudest chapters: victories at the Indianapolis 500 in 1939 and 1940. By the time this cap was likely produced, the Indy had been out of production for a few years, but its place in the Italian GT canon was secure. The “Italia” label printed alongside the car’s name reflects something real about how these vehicles were perceived in Japan — national origin was part of the appeal, a signal of authenticity and prestige in a market that had developed a genuine passion for European exotics.

Japan’s Supercar Boom and the Crown Cap Collecting Tradition

Two interwoven phenomena help explain why a Maserati ended up on a Japanese bottle cap.

The first is the Supercar Boom, which swept Japan from roughly 1975 to 1979. Sparked largely by the manga “Circuit no Okami” (Wolf of the Circuit), which began serialization in 1975, European exotic cars captured the imagination of Japanese children and teenagers with surprising intensity. Ferrari, Lamborghini, and Maserati merchandise — model kits, erasers, sticker cards, and more — flooded the market to meet that enthusiasm.

The second is Japan’s crown cap collecting culture. Bottle cap collecting had existed as a children’s pastime since at least the mid-Showa era, but beverage companies eventually formalized it into a marketing tool: themed series featuring sports cars, trains, or baseball players were designed so that kids would chase a complete set, trading duplicates with friends and returning to find missing designs. As a format, it sits alongside Glico candy prizes and Bikkuri Man stickers as a distinctly Japanese way of bundling a collectible into an everyday purchase — distinct from gashapon in that it was tied to buying a bottled drink rather than dropping a coin in a machine.

A Maserati Indy cap lands at the crossroads of both phenomena. For collectors today, it draws interest from multiple directions: Italian automobile enthusiasts, students of Showa-era Japanese popular culture, and those drawn to the Supercar Boom as a specific cultural episode each find something to engage with here.
