The Three Participating Creators

Three creators from the “dot Label” collective—NERDOG, Mominin, and Yamada Yum—will participate in this pop-up. Their distinct styles and creative worlds will come together in a single space.

NERDOG

An illustrator whose work centers on character illustrations, particularly his original character “NERDOG.” His style is characterized by a relaxed, hand-drawn feel and a simple aesthetic based on white backgrounds; he gained attention through the LINE sticker “NERDOG’s Relaxed Daily Life” brought her into the spotlight.

She has expanded her reach beyond exhibiting at events like COMITIA and Design Festa to include group exhibitions and commissioned original artwork sessions. For this joint pop-up event, she has significantly expanded her lineup to include not only original artwork and merchandise but also fabric goods. In addition to cushions, the first-ever “NERDOG” plush toys—a first for the series!

Mominin-sensei

An illustrator who creates manga centered on her original character “Momi-Ham,” as well as other illustration works. Her signature style features a loose, relaxed touch and humor born from facial expressions, mannerisms, and interactions between characters; she also creates standalone illustrations with a style quite different from her comics.

A crowdfunding campaign featuring “Momi Ham” exceeded its target amount by over 240%. This time, in addition to exhibiting original artwork and the ceramic “Merikomi Ham Cup”—which generated a huge response on social media— —which garnered a huge response on social media—will be on display, and original merchandise that allows fans to experience the “Momi Ham” universe firsthand will be available for purchase.
