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



“Opanchu Usagi (Blue)” is a Weeks book with a lively design of various Opanchu Usagi drawn all over the cover. The Opanchu Usagi in different expressions will make your day lively and colorful.







You might notice the one placed near the center of the cover, which has a Hobonichi Techo and a pencil in its hand. It is a special feature of this techo.







The pop typeface "2023" is in bright pink.







The spine of the cover is in the same pink color, with the Opanchu Usagi logo, “2023” wearing a symbolic blue ribbon, and an Opanchu.

When you order this Hobonichi Techo Weeks, you’ll receive a clear, adhesive corner pocket you can stick anywhere you like.







When you purchase your Hobonichi Techo through the online Hobonichi Store, you will receive a free 2023-edition (navy x brown pen body) Hobonichi Store exclusive 3-color Jetstream ballpoint pen (available while supplies last).

*The 3-Color Jetstream Ballpoint Pen offer has ended.







If you’d like storage space or a way to change up the look of your Weeks book, you can customize your book by pairing it with a Weeks cover.

For each “Opanchu Usagi” item you purchase at either the Hobonichi Techo Official Website, Tobichi Tokyo, or Tobichi Kyoto, you will receive one “Opanchu Usagi #Teru-teru tissue paper.” The bonus includes a pocket tissue pack, a sticker with Opanchu Usagi’s face, and a wrapping tie to hold the tissue paper. You can use them to make an Opanchu Usagi “Teru-teru bozu” doll of your own!




The “Teru-teru tissue paper” bonuses are available while supplies last.
*Supplies of the “Teru-teru tissue paper” have ended.

We now have many items in the Opanchu Usagi design, such as the techo, pencil board, memo pad, and sticker set. It would be so much fun using them together!
