They create these super charming mascot characters to connect with everyone, making a serious topic feel way more approachable and warm.

Meet the Adorable Crew
So, who are the stars of this sticker show? The sticker set is a collaboration, bringing together a few key characters to celebrate a special occasion. While we don’t have their full life stories, their designs tell us a lot about the vibe CO-OP Kyosai is going for.
Kosuke: The Friendly Red Bear
The main character here seems to be COSUKE, the cheerful red bear. You’ll spot him in every sticker, often with a little “C” on his chest, probably for “CO-OP.” He’s the face of the brand, a friendly and expressive little guy who helps convey all sorts of emotions. Characters like him are a huge deal in Japan. They’re called yuru-kyara, or mascots, and they’re used by all sorts of organizations to create a soft, welcoming image.
Tanuro and the Baby Animals
Joining COSUKE is a cute brown owl-like character, Tanuro, and a whole bunch of baby animals! There’s a sleepy puppy, a tiny kitten, and a little chick. These characters act as the perfect sidekicks, adding an extra layer of cuteness to the whole set. This team-up seems designed to celebrate the first anniversary of CO-OP Kyosai’s pre-birth registration service, so including baby animals is a perfectly sweet touch.
A Tour Through the Sticker Pack
This sticker pack is basically a bundle of pure, concentrated cuteness. It’s got eight different designs, each one perfect for dropping into a chat to add a little flair. They cover a whole range of everyday expressions and feelings.
The top row kicks things off with some classic interactions. First, you have Kosuke giving a polite bow, or a pekori, to a sleepy little puppy. Next, a proud Tanuro gives Kosuke a thumbs-up and a pat, which seems to surprise our red bear. Then there’s an incredibly sweet moment where Kosuke is hugging a tiny kitten with the message “Otsukaresama,” which is a lovely way to tell someone “good work” or “you’ve worked hard.” The row finishes with a sparkly, overjoyed Kosuke shouting “Arigatou” or “Thank you!”—you can almost feel the gratitude beaming off the screen.
Moving to the bottom row, the expressions continue. We see Kosuke and Tanuro nodding in agreement with a hearty “Un un,” which is the Japanese sound for “uh-huh.” Things get super romantic in the next sticker, where Kosuke floats dreamily with a little chick, surrounded by pink hearts. But it’s not all sunshine and rainbows; the next sticker shows a dramatic Kosuke literally melting into a puddle of his own tears. It’s both sad and hilarious. Finally, the set wraps up with Kosuke and Tanuro looking flustered and surrounded by blue stress marks, a feeling we can all relate to sometimes!
More Than Just Cute Stickers
So, why would an insurance cooperative put so much effort into creating these adorable digital stickers? It’s actually a brilliant marketing strategy that’s deeply rooted in modern Japanese culture. By offering these free stickers, CO-OP Kyosai isn’t just giving away cute art; they’re embedding their brand into people’s daily conversations on platforms like LINE and WhatsApp. Every time someone sends a sticker of Kosuke crying a river or hugging a kitten, the CO-OP brand gets a little bit of friendly exposure. It’s a soft-sell approach that builds a positive and relatable identity, making the company seem less like a faceless corporation and more like a helpful friend.
This whole campaign is tied to the 1st anniversary of their pre-birth registration service, which is a perfect fit. The theme of “baby animals” directly connects to the service they’re promoting without being pushy. It’s a celebration, and these stickers feel like fun, digital party favors for their members and potential customers. It’s a win-win: users get fun, expressive stickers for free, and the company builds brand loyalty and awareness in a way that feels organic and fun.
Protecting Their Cute Creations
Of course, when you create characters this charming, you want to protect them. That’s where the “CO.OP All Rights Reserved” notice comes in. This is a standard copyright statement, but it’s really important. It means that the intellectual property—the designs of Kosuke, Tanuro, and all the artwork—belongs exclusively to CO-OP. They have full legal control over how these characters are used, reproduced, or distributed. This prevents others from using their mascots without permission, which could dilute the brand’s image or be used in ways that don’t align with their values. These characters are valuable assets, the face of their friendly approach, so protecting them is a top priority for the organization.
