About the Wearable Memo "wemo®" Series
"wemo" is a wearable memo brand built on the philosophy of "easing the stress of remembering." Launched in 2017, "wemo Band Type" can be worn around the wrist at all times, easing the physical and mental burden of memory — the hassle of digging out a notepad when something needs to be jotted down in a hurry, or the risk of forgetting what was written. Made from silicone rubber with a proprietary coating, it can be written on with an oil-based ballpoint pen and erased with an eraser or a finger, over and over again. Since the debut of "wemo Band Type," the brand has expanded into pad-style memos that stick repeatedly to laptops, smartphones, desks, and more — including "wemo Pad Type" and "wemo Pad Type ver.2" — along with a range of reusable, eco-friendly memo products suited to different purposes and occasions. As of 2026, the brand has picked up five wins and three nominations across the Japan Stationery Awards, the Stationery of the Year vote, and the Stationery Shop Awards, along with 14 wins in total including other awards, earning support as a brand that keeps challenging conventional thinking.
By continually listening to user feedback and developing collaboration products with other brands, the series grew into a hit product, surpassing cumulative sales of 1 million units in autumn 2023, six years after its debut.

Development Background of the Collaboration Product "wemo PETTA®" Series
The collaboration between the two companies first came about in 2025, born from Yamato Co., Ltd.'s affinity for adhesive-based product development and its empathy for the wemo series' pursuit of the usability unique to analog tools amid the digitization of every kind of tool. Building on the popular "wemo Pad Type ver.2" and its function as an "eco-friendly sticky note," "wemo PETTA" was created by adding a cute design that is distinctly Yamato and unlike anything in the series before it. The first installment, the "Animal Series" released in June 2025, drew a strong response, selling out at events such as the Stationery Girls Expo, and the second installment, the "Tasty Memo Series," followed swiftly in February 2026. Now, as the third installment, the "Nyanko Series" has been decided, putting the spotlight on cats, which proved especially popular within the "Animal Series."

Fun to Use, and It Also Supports Animal Welfare! About the "wemo PETTA® Nyanko Series"
As with the previous installments, the "wemo Pad Type" series' function of writing, erasing, sticking, and peeling repeatedly stays the same, with three new adorable cat back-view designs that stick on with a light pat. This time, the notes are also a size larger than previous PETTA releases, making it easier to jot down several to-do items or longer messages. The lineup comes in three coat-pattern designs — Socks, Chabuchi (brown patched), and Kijitora (brown tabby).
They are easy to use around an office desk or in the kitchen, and are also well suited to sticking on the back of a smartphone for carrying around. Stuck somewhere visible as a memo while working or studying, they double as a fun-to-look-at reminder. At home, they can also serve as a heartwarming communication tool, used to write a menu or a message and stick it on a family member's bento box.
A portion of the sales of this "Nyanko Series" is also donated by Yamato Co., Ltd. through Animal Donation, a public interest incorporated association that runs Japan's first donation site dedicated to animals, to certified organizations that carry out animal welfare activities. Enjoying the notes as an everyday memo directly translates into support for animal welfare.
