The GREEN×EXPO Association (International Horticultural Exposition 2027 Association) and the 2027 International Horticultural Exposition Master License Office will release collaborative merchandise featuring the official mascot “Tunktunk” and the Osaka-Kansai Expo 2025 official character “Myakumyak” on September 23.
This marks the first collaborative merchandise for Tunktunk, with five items available including A4 files and keychains. The “Myakumyak Tunktunk A4 Clear File” (520 yen) shows Tunktunk facing forward alongside Myakumyak joyfully spreading its arms, as if taking a commemorative photo. The “Myakumyak Tunktunk Acrylic Keychain” (770 yen) and “Myakumyak Tunktunk Sticker” (660 yen) depict them holding hands while walking together. The “Myakumyak Tunktunk Can Magnet” (660 yen) shows them sitting together on a picnic sheet, each with a different design.
Additionally, “Kiyoken Yokohama Pineapple Cake Brown Sugar” will also be released in special collaborative packaging featuring Tunktunk and Myakumyak. The pineapple cake features rich pineapple jam wrapped in a dough blended with butter and Okinawan brown sugar, then baked. It is characterized by the moist texture of the dough, the deep flavor of brown sugar, and the pineapple flavor that spreads throughout the mouth, “embodying the wish to connect the Expo from Osaka to Yokohama.”
The merchandise will be available at EXPO 2027 Official Store “Yokohama Luxis Front Store,” “Maruzen Yokohama Minatomirai Store,” and the “EXPO 2027 Official Online Store,” among others. The cake will also be sold at Kiyoken.
In Osaka, an “EXPO 2027 Official Pop-up Store” will be set up for a limited time on the first floor of MARUZEN&JUNKUDO BOOKSTORE Umeda Store, offering both existing goods and the collaborative items. On September 24, the day after opening, a photo session with “Tunktunk” and “Myakumyak” will be held by prior reservation.
