Korean frozen yogurt brand YOAJUNG is opening at the Silver Week Festival held at Nishi-Okubo Park from Saturday, September 19 to Wednesday, September 23 (a national holiday), 2026.
During the event, a YOAJUNG kitchen car will sell frozen yogurt, offering two special combos created exclusively for the festival alongside the brand's four signature regular combos.
The festival is held to spread out the flow of visitors who would otherwise concentrate around Okubo-dori during Silver Week, easing congestion and helping generate liveliness in the area. Nishi-Okubo Park, which is used as a dining and rest space, will let visitors enjoy YOAJUNG's frozen yogurt on-site.
Two Festival-Exclusive Combos
For this pop-up, YOAJUNG developed two special combos to mark the event.
Nishi-Okubo Combo — ¥1,180 (tax included)
A festival-exclusive combo topped with walnut confectionery. It pairs the refreshing taste of the frozen yogurt with the toasty aroma and texture of the walnut confectionery.
Mini Tomato Combo — ¥1,800 (tax included)
A limited combo that pairs frozen yogurt with mini tomatoes, bringing out the frozen yogurt's refreshing tartness alongside the fresh flavor of the tomatoes.
Four Regular Combos
In addition to the limited combos, YOAJUNG's four signature regular combos will also be on sale.
Choco Cube Cheese Combo — ¥1,250 (tax included)
Sweets Grapefruit Combo — ¥1,350 (tax included)
Blueberry Combo — ¥1,350 (tax included)
Yoajung Signature Combo — ¥1,250 (tax included)
A large visual of TOMORROW X TOGETHER, YOAJUNG's official model, is displayed on the back of the kitchen car, creating a photo spot visitors can freely use.
A single kitchen car featuring YOAJUNG's original design will be set up at the venue, serving items for takeout. Next to the kitchen car, Korean sweets brand OKUDANG will also sell its Dubai Mochi Cookie (ドゥチョンク).
A DERMAGENCY promotional booth will also be on-site, with product displays and a free prize-draw lottery. Prizes from DERMAGENCY are given on the spot based on the draw results. The booth operates from 12:00 PM to 6:00 PM.
