Hello Kitty’s ATEEZ Collab Collection Officially Returns for Limited-Time Pop-Up
Image by James RichardsonThe ATEEZ × Hello Kitty “Black Series” collection is getting a dedicated pop-up shop this October, bringing the previously released collaboration merchandise together with newly added products, exclusive displays and event-only activities.
The limited-time event will be held at MIL GALLERY in Tokyo, following the collection’s online launch in August, giving fans a physical venue dedicated entirely to the collaboration.

ATEEZ is an eight-member South Korean group consisting of Hongjoong, Seonghwa, Yunho, Yeosang, San, Mingi, Wooyoung and Jongho, while Hello Kitty has remained one of Sanrio’s best-known characters since her debut in 1974.

The collaboration marks the first time Hello Kitty’s “Black Series,” which reimagines the character through a predominantly black visual style, has teamed up with a K-pop artist.

Merchandise from the collection first went on sale online on August 24, with further products subsequently added ahead of the physical pop-up opening in October.
The expanded lineup includes three Hello Kitty figures supplied with T-shirts alongside apparel, hoodies, bags, pouches, a tumbler bottle, plush keyrings, light stick accessories and other smaller collectibles.

A separate random-item collection will be exclusive to the physical pop-up, adding merchandise that will not be available through the standard online range.

The venue will also display an approximately 70-centimeter Hello Kitty figure signed by the members of ATEEZ, alongside large group visuals, Black Series displays and a space where visitors can leave messages for the group.

Fans purchasing one of the three collaboration figures will have a chance to receive a randomly inserted card carrying an ATEEZ member’s handwritten signature, with both the member and design selected at random.
Customers spending ¥8,000 or more on eligible merchandise at the venue will receive one randomly selected photo card from eight designs, with another card available for each additional ¥8,000 spent.

Online purchases use a separate eight-design photo-card collection, although customers selecting physical event pickup will receive the same bonus designs distributed through the pop-up.
The collection remains available through the ONETODAY online store, with delivery orders continuing through November 15 while stocks last, although international shipping is not offered.

Admission to the pop-up uses advance 30-minute reservation slots, with general reservations offered on a first-come basis and possible walk-in admission introduced on individual days if capacity allows.
The ATEEZ × Hello Kitty “Black Series” POP-UP STORE will run from October 16 through October 25, 2026 at MIL GALLERY JINGUMAE, 2F, 4-25-28 Jingumae, Shibuya, Tokyo.
The store will open from 10:00 AM until 8:00 PM, with final admission at 7:30 PM each day.
