How to Find SEGA Plaza Detective Conan Prize Merch on Mercari

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.
