The 'Custom-kun Plushie Book' featuring the customs service's official mascot Custom-kun will be released on July 2, 2026 (Thu). This limited-edition item included exclusively with the book is a generously sized, luxuriously soft plush toy of Custom-kun that's irresistibly huggable. Its delightfully squishy texture makes it perfect for relaxation time, and its one-body-style round silhouette is another charming highlight. The book's pages feature content explaining customs jobs you might think you know but don't, as well as articles where Custom-kun takes on the role of guest editor for a day. Faithfully capturing his round eyes and chubby body—the design pays special attention to his one-body proportions A voluminous body perfectly sized for hugging [Who is Custom-kun?] Custom-kun is the official mascot character of Japan's customs service, modeled after narcotics detection dogs. He actively contributes to customs outreach and public awareness campaigns across various platforms! His name comes from the English word "CUSTOMS." Despite his cute appearance, he communicates the serious realities of customs work—smuggling, couriers, seizures, and more. His "Smuggling Hotline Song," posted on May 28 this year, received over 22,000 likes on Instagram. The irregularly posted "Customs Quizzes" on X frequently become talking points for their surprisingly intense and dramatic content. The striking contrast between his laid-back, adorable look and the serious nature of customs work is what makes Custom-kun a truly one-of-a-kind character. Nine Public Relations Offices Across Japan and Their Local Custom-kun Custom-kun figures stationed at nine different customs offices across Japan each have unique colors and designs, adding individual charm. This "variation among individuals" is one of the reasons fans love them.
