A new cookie tin inspired by the whimsical world of Kojikōji is set to dazzle fans. The “Kojikōji no Lamp Kan” (Kojikōji Lamp Tin) will debut at Isetan Shinjuku on July 4, 2026, as part of a collaboration with health-conscious sweets brand Aoyama Decarbo.
Design Details
The tin’s lid features Kojikōji and a lamp surrounded by glittering constellations. The lamp motif is embossed in colors that harmonize with Kojikōji’s palette. Among the 12 zodiac signs, a playful detail shows Jiro posing as Sagittarius while watching over Kojikōji.
The side of the tin is equally elaborate, depicting a magic carpet, star-shaped balloons, Kojikōji, and the lamp. Tile-patterned sections hide familiar faces from the series. When the lid is opened, Teruko peeks from the rim, and Perro-chan and a boiling kettle-kun are tucked away.
On the bottom, a special carpet with Kojikōji is printed. Peel off the sticker on the reverse side to reveal an adorable illustration of Kojikōji sleeping on the moon. The design merges Kojikōji’s fairy-tale charm with Aoyama Decarbo’s jewel-like glass art.
Figurines and Cookies
Each tin comes with one of three collectible Kojikōji figurines. Each figurine wears a lamp-appropriate outfit and holds the lamp behind its back, in its right hand, or on its head.
The cookies inside are plant-based lemon butter flavor, made with rice flour for a gluten-free treat. Lemon peel adds a refreshing scent, while soy milk cream butter leaves a gentle aftertaste.
Limited Accessories
To complement the tin, a new “Star Light Tassel Chain” (Hoshi Akari no Tassel Chain) is available exclusively for purchasers of the lamp tin. The chain features a swinging tassel design adorned with 1.3mm stones that evoke a starry night.
A special set limited to 300 units combines the lamp tin, the tassel chain, and a “Glittering Miniature Tea Set” (Kirameku Miniature Ocha-kai Set). The set’s box replaces a ribbon with star-like accessory parts that seem to capture starlight.
The miniature tea set comes in three colors: red, yellow, and blue. Despite its small size, the detailed patterns enhance the fantasy world of the lamp tin. The teacups and pot are magnetically fixed to the tray, allowing rearrangement. The central pot can also serve as a small container for accessories.
