KAWAISOUNI!: Opanchu Usagi (Stationery) A5 Cousin Size - Techo Lineup

KAWAISOUNI!Opanchu Usagi (Stationery)A5 Cousin Size

“Opanchu Usagi” is a character illustrated by KAWAISOUNI!, an illustrator and animator especially popular on social media. The Opanchu Usagi wearing a large “Opanchu” underwear and always in a somewhat “Kawaisou” pitiful situation gives a sense of indescribable cuteness and melancholy.

“Opanchu Usagi (Stationery)” is a bright yellow techo cover that cheers you up just by the look of it. You can find Opanchu Usagi in various styles with illustrations of pencils, erasers, paper clips, and other stationery items unique to Hobonichi Techo. The trifold design snaps shut with a button. The Hobonichi logo is foil-pressed in silver on the flap.

Made of light and soft PVC material, transparent parts with printed illustrations overlay the yellow background.

The front side has a pocket for small stationery items like sticky notes and rulers.

On the inside, to the left, are two transparent pockets for cards. The upper flap can be used as a bookmark by inserting it into the techo.

The pocket on the inside to the right is handy for keeping postcards and tickets. The pen hook is designed to hold a pen by its clip.

The back side also has a large pocket for cards and other items.

With this cover, you can always have the cute Opanchu Usagi at your side.

The lineup for Opanchu Usagi includes a techo, pencil board, memo pad, sticker set, and more. Using them together would make it even more fun!

In the Hobonichi Techo 2025 lineup, the Cousin book comes in either English or Japanese.

*The English book is only available as the January-start version.

For all those who relate to “Opanchu Usagi”

As creators of the Hobonichi Techo, we love “Opanchu Usagi!” We decided to create a techo cover, Weeks book, and so much stationery following the “Hobonichi Techo 2023 Spring.”

Opanchu Usagi is so popular that there are already many goods out there. We decided to create items that are cute, high quality, and truly Hobonichi. And since Opanchu Usagi has been evolving more and more since its first appearance, such as facial expressions showing various emotions, we made sure to keep those faces and poses in mind.

The illustrations of stationery on the techo covers and stationery were created just for this techo. We also wanted a stationery product with them, so we even made a mini card set.

We made “Opanchu Usagi (Stationery)” made of casual PVC material to make young Opanchu Usagi fans comfortable. You can use it conveniently and enjoyably with functional pockets on the front and back.

The illustrations of seasonal items on the Weeks book are also exclusive to the techo. We are glad we could have these illustrations that give a sense of the seasons since the Weeks book is used up over the year.

We hope you have fun with every detail of the illustrations on the techo and stationery!
