A Closer Look at the Cuteness

This sticker pack is basically a bundle of pure joy and everyday expressions, made even better by this unexpected duo. The soft, watercolor-like art style makes every single sticker feel warm and gentle. Let’s break down what you get in this awesome set.

The Daily Grind Made Adorable

The first row is packed with perfect reactions for work or just getting through the day. First up, we see a very professional-looking Mimamorisu in a suit standing next to a supportive Koupen-chan, who is giving a little wave. The text reads “Ryoukai desu,” which is a polite way of saying “Roger that” or “Understood.” Next to it, Koupen-chan is all by itself, happily holding a four-leaf clover with the message “Otsukaresama desu,” a classic Japanese phrase for “Thank you for your hard work.” Then there’s a simple but powerful sticker of a tiny Koupen-chan getting praised with a giant speech bubble exclaiming “Erai!” or “Amazing!” To round out the row, Koupen-chan says “Ohayou gozaimasu” (Good morning) while holding a cool blue pack, looking ready to face the day.

Sweet, Simple, and Super Relatable

The bottom row captures some incredibly relatable and sweet moments. The first one is a summer mood for sure: Koupen-chan has literally melted into a puddle from the heat while a frantic Mimamorisu tries to fan it cool. The text simply says “Atsui…” (“It’s hot…”). Following that is a polite Koupen-chan in a deep bow, with the onomatopoeia “Pekori” representing the action of bowing. Then, get ready for your heart to melt with a close-up of Koupen-chan looking up with huge, grateful eyes, surrounded by sparkles, saying “Arigatou gozaimasu” (Thank you very much). Finally, the set ends on the coziest note possible: Koupen-chan, wearing a little blue sleeping cap, is fast asleep on a fluffy cloud under a starry night sky, wishing you “Oyasuminasai” (Good night).

So, Who’s Behind This Adorable Partnership?

It’s always fascinating to see how these collaborations come together, especially when they mix a beloved indie character with a major corporation. It’s a perfect blend of creativity and marketing.

RURUTEA: The Creator of Everyone’s Favorite Penguin

At the heart of this sticker set is, of course, Koupen-chan. This little emperor penguin chick is the creation of the artist RURUTEA. If you’ve spent any time online, you’ve likely seen Koupen-chan. The character’s whole deal is offering simple, unconditional praise and encouragement. Whether it’s for waking up on time or just trying your best, Koupen-chan is there to tell you you’re doing great. This wholesome and positive energy is what made the character a massive hit, and RURUTEA holds the copyright to this wonderful creation. It’s this universal appeal that makes Koupen-chan a perfect partner for collaborations.

DAI-ICHI LIFE: More Than Just an Insurance Company

On the other side of this team-up is THE DAI-ICHI LIFE INSURANCE COMPANY. As one of Japan’s oldest and largest life insurers, they’re a huge corporate entity. So why the cute hamster? That’s Mimamorisu, their brand character for a service called “DigiHo.” Partnering with a character as famous as Koupen-chan is a pretty brilliant move. It instantly makes their brand feel more friendly, modern, and approachable. By creating these stickers, Dai-ichi Life isn’t just advertising; they’re offering something fun and useful for daily digital conversations. They hold the copyright for Mimamorisu, and for this specific sticker set, they share a joint copyright with RURUTEA, which is standard practice for these kinds of partnerships.
