Cogimyun is heading to a colorful lagoon for an adorable new Sanrio merchandise collection filled with summery artwork and a selection of new collectibles.

The new “Cogimyun Lagoon” range will headline a limited-time Cogimyun POP-UP STORE x Munyugurumi Patio event at Tokyo Station, with everything from a plush mascot to holographic accessories available for fans to collect.

Cogimyun is a Sanrio character who was born from wheat flour and dreams of becoming an onigiri despite not actually being made from rice, with her tiny size and tendency to scatter into flour when surprised contributing to her particularly delicate personality.

A selection of new merchandise featuring the lagoon-themed Cogimyun artwork will be available at the event, including:

Mascot – ¥2,310 (approx. $16 USD/ £12 GBP)

Hand Towel – ¥770 (approx. $5 USD/ £4 GBP)

Hologram Pin Badge – ¥550 each (approx. $4 USD/ £3 GBP), with two designs available

Hologram Sticker – ¥330 each (approx. $2 USD/ £2 GBP), with two designs available

Acrylic Keychain – ¥880 (approx. $6 USD/ £5 GBP)

Acrylic Stand – ¥880 (approx. $6 USD/ £5 GBP)

Postcard Set – ¥385 (approx. $3 USD/ £2 GBP)

The collection brings the lagoon artwork to a mixture of display pieces, everyday accessories and smaller collectibles, with the holographic finishes adding an extra colorful touch to the summer theme.

Customers will also be able to receive an exclusive visual card when purchasing eligible Sanrio merchandise during the event, with two different designs available.

One randomly selected visual card will be given away for every ¥3,300 (approx. $22 USD/ £17 GBP) spent on Sanrio products in a single transaction, including items from the Cogimyun Lagoon collection.

The purchase bonus will be available from August 14 while supplies last, with customers unable to choose their card design or combine separate receipts to reach the required spending amount.

The Cogimyun POP-UP STORE x Munyugurumi Patio will be held beneath the G Staircase at Tokyo Character Street inside Tokyo Station First Avenue from August 14 through August 27, 2026.

The pop-up store will operate from 10:00 a.m. until 8:30 p.m. throughout the event, with an earlier closing time of 6:00 p.m. on August 27.

Fans unable to visit Tokyo will also be able to purchase the merchandise through the Tokyo Station Character Street Online Plaza from 10:00 a.m. on August 14 until 11:59 p.m. on August 27, with qualifying online purchases also eligible for the visual card promotion while supplies remain.
