Snackgirls react

Kirari: That fluffy belly patch makes me want to reach out and touch it! The blue-and-white striped tote is the one I’d plan an outfit around, though.

Nea: The “SIDE by SIDE” portrait makes me curious about Booska and Chamegon’s relationship. For the 60th anniversary, I’d like to look back at where their story began.

A little belly patch to carry around

The belly-and-back series puts cream-colored boa-fabric belly patches on a yellow tote, drawstring pouch and carabiner mini pouch. Prices include tax: the tote is ¥2,500 and the drawstring pouch is ¥1,500.

The stationery turns those character details into printed designs. An A4 clear file and B6 ring notebook feature the belly, while an A5 clear file uses the red-purple spots from Booska’s back.

Striped bags and a side-by-side portrait

Another range borrows the blue-and-white stripes from the pants Booska wears in the show, applying the pattern to bags and a hand towel. Orange accents and “BARASA! BARASA!” patches complete the bag designs.

The Booska & Chamegon series offers both a “SIDE by SIDE” portrait of the pair and a retro design with English text about Booska’s origins. The lineup includes bandanas, two tote designs and a ¥3,500 T-shirt available in S, M, L and XL.

Nine badge designs, plus one secret

The blind-pack can badges cost ¥330 each, with nine regular designs and one secret design—ten in total. The blind acrylic keyholders are ¥800 each and come in ten designs. In both cases, the design inside is a surprise.

Find it outside the Central East ticket gates

The pop-up runs October 28–November 10, 2026, on B1 of LUMINE EST Shinjuku, outside the Central East ticket gates in front of Aoyama Flower Market.

The event marks 60 years since Kaiju Booska began airing in 1966. Booska’s November 9 birthday also falls during the run.

Online sales are not currently planned, so anyone hoping to shop the range will need to visit the Shinjuku pop-up during its run.
