(Headquarters: Koto-ku, Tokyo), until Tuesday, April 21, 2026, as part of the spring promotion "BLOOM your own."

During the event period, there are plans to distribute Lost Flowers® to customers making purchases, allowing them to experience new value and enjoyment along with the underlying story.

## Spring Promotion "BLOOM your own"
Flowers each have their own individuality.
Short stems, bent stems, slightly misshapen flowers.
No two are exactly alike.
Each is different, yet all are beautiful.
This spring 2026, bloom. Be yourself.

## Visualizing the Story from Flower Production to Spatial Decoration in a 30-Second Video
At the 1st-floor concourse of Daimaru Tokyo Store, video content utilizing digital signage will be broadcast. The video introduces the process from when flowers arrive at RIN's atelier, undergo initial treatment, and are reborn as dried flowers. Furthermore, it condenses the process of the finished dried flowers being transported to Daimaru Tokyo Store and displayed as in-store decorations into approximately 30 seconds. By visualizing the story from flower production to spatial decoration, the aim is to deepen visitors' understanding of the flowers' background and sustainable initiatives.

## Spring Decorations Adorned with Lost Flowers®
Spatial presentations utilizing Lost Flowers® will be developed at the 1st-floor show window, the main entrance to Daimaru Tokyo Store, and various other locations within the store. The decorations use Lost Flowers® dried from flowers from three flower farms. By arranging each flower individually on the walls, the display highlights the unique character and beauty of each flower. The color scheme is based on warm tones such as mandarin orange and flamingo, creating a gorgeous space throughout the store that evokes the arrival of spring.
Furthermore, a portion of the Lost Flowers® used in the spatial decorations will be distributed to visitors on the last two days of the event, April 18 (Saturday) and 19 (Sunday), with a limit of 100 people per day ※2. By not discarding the flowers used in the spatial decorations but passing them on to visitors, RIN aims to promote the circulation of Lost Flowers® and provide an opportunity for people to experience their value firsthand.
※2 Limited to Daimaru/Matsuzakaya app members. Customers who spend ¥11,000 (tax included) or more in a single receipt at eligible departments between April 1st (Wednesday) and April 19th (Sunday) are eligible.
