Some of the coolest 30th-anniversary merchandise won’t be found in retail stores at all. SEGA Plaza is introducing a legendary lineup of limited-edition amusement prize items across Japanese arcades. These high-demand items include a 2026 version of Conan’s iconic Wristwatch Stun Gun, an oversized Bowtie Voice Changer cushion, and giant APTX-4869 capsule plushies.

Because these are arcade exclusives, they are strictly “not for sale” through traditional retail or international storefronts.

Fortunately, there is an expert insider secret to securing them: Japan’s thriving secondary and secondhand markets! Many Japanese players list these mint-condition crane game prizes directly onto Mercari, Japan’s largest peer-to-peer marketplace. By using Buyee’s integrated search bar, you can search Mercari directly in English, browse listings for these rare SEGA Plaza prizes, and safely buy Detective Conan arcade merch from Japan. It is the ultimate shortcut for overseas collectors looking to find rare, unreleased items without leaving home!
