A Whole Sheet of Cuteness: Let’s Look at the Stickers!
This sticker pack is basically a full-course meal of adorable expressions. The collection is laid out in a grid, featuring Sirotan, the fluffy white seal, and its equally cute friends, including a brown seal and a little blue penguin. The first row kicks off with two friends waving hello, followed by a brown seal giving a big OK while holding a tiny blue cloud buddy. Then you have Sirotan floating in a frame of pink hearts, looking absolutely content. A sleepy-looking penguin character rounds out the row, nodding along with a tiny friend.
The expressions cover all your daily needs. There’s a sticker of the gang cheering with a big すごい!! (sugoi!!), which means “Awesome!”. You’ll also find two characters bowing politely to say よろしくおねがいします (yoroshiku onegaishimasu), a classic Japanese greeting. Need to show gratitude? A group of characters is gathered on a pink cloud to say ありがとうございます (arigatou gozaimasu), or “Thank you very much.” For those sleepy moments, there’s a sticker of the crew tucked into bed under a blue blanket, wishing you a sweet おやすみなさい (oyasuminasai), or “Good night.” And for the end of a long day, the penguin character holds a star wand, looking tired and saying おつかれ (otsukare), meaning “Good work.”
The set also includes some super fun and casual reactions. A whole group of friends jumps for joy with a cheerful イエーイ! (Yēi!), which is just “Yay!”. Another sticker shows a trio bowing deeply with the onomatopoeia ペコリ (pekori), the sound of bowing. And for those lazy days, one of the funniest stickers shows a brown character sprawled out on its back, just scrolling on its phone with the text ゴロ ゴロ (goro goro), which perfectly captures the feeling of lazing around. From waking up to winding down, this pack has a charming sticker for everything.
The Team Behind the Seals: Yahoo! JAPAN and CREATIVE YOKO
So, who are the masterminds that brought this heartwarming sticker set to our screens? It’s a fantastic collaboration between a giant distributor and a dedicated creator. On one side, you have Yahoo! JAPAN acting as the publisher. They’re not just some random company; they are a massive presence in Japan’s digital world. By releasing these stickers, they give their huge user base something fun and engaging to use, making their platform stickier and more enjoyable. It’s a clever way to build brand loyalty and keep people coming back.
The Heart and Soul: CREATIVE YOKO
While Yahoo! JAPAN gets the stickers out there, the real magic comes from CREATIVE YOKO CO., LTD. This is the company that actually owns, created, and designed the beloved Sirotan character. Founded way back in 1981, this Japanese company, based in Nagano, is an expert in creating character goods that people fall in love with. They aren’t just a design firm; they are what’s known as an SPA (Specialty store retailer of Private label Apparel), which is a fancy way of saying they control everything from the initial idea and design to producing the products and selling them in their own shops. This total control ensures that the quality and essence of characters like Sirotan remain pure and consistent. They hold the copyright to these stickers, so every fluffy detail and charming expression is authentically theirs.
A Perfect Partnership
This team-up is a classic win-win. CREATIVE YOKO gets to introduce Sirotan and its friends to the millions of people using Yahoo! JAPAN’s services, while Yahoo! JAPAN gets exclusive, high-quality content that makes its users happy. The design of Sirotan itself is brilliant. As a character based on a seal, it’s naturally soft, calming, and endearing. Its simple, round, and fluffy appearance has a universal appeal that’s hard to resist. These stickers tap right into that charm, offering a visual and emotional shorthand for everyday messages that plain text just can’t match. They make digital chats feel a little more human and a lot more fun.
