100%ORANGESquirrel’s Moving DayWeeks Hardcover Book / Weekly Horizontal / ENG or JPN edition / Jan start / Mon start

2026 New

The picture book Ohikosshi illustrated by 100%ORANGE is now available on a Hobonichi Techo Weeks.

Ohikkoshi was first released in the monthly magazine Ohanashi Pooka in 2007, and published as a picture book the following year. The squirrels all cross the bridge, go down the stairs and just when you think they all made their way across the street, they climb up the wire fence for a short rest...The sight of them all walking together, one after another, is somehow both delightful and refreshing.

The front cover showcases an arrangement of the original picture book cover. Various unique squirrels—one wearing a hat, another holding an apple and yet another holding an umbrella, among others—are placed in a grid made with markers in colors like red and light blue. While undoubtedly charming and adorable, this design’s graphical style also gives it a cool edge. The hardcover is made out of a sturdy yet flexible material and features a finely textured surface.

On the front cover, the year 2026 is foil-pressed in red, while the spine features the year in white foil.

The back cover includes 100%ORANGE’s signature.

Stationery to match the techo cover and Weeks is also available, so you can immerse yourself in the world of the picture book hikkoshi by using them together.

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

The book uses thin and light yet durable Tomoe River paper. It's characterized by its ability to hold ink well and provide a smooth writing experience.

The Weeks book has space for writing in plans or journal entries, and it also has 71 pages of grid paper memo pages in the back (75 pages in the English edition). The back of the book contains bonus pages, including Memories 2026 and 12 Switches to Help You Focus.

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.

The story behind the making of the picture book Ohikkoshi

How did they come up with the idea of a story all about a big move for a group of squirrels? We asked the duo behind the name 100%ORANGE about the behind the scenes of their 2007 picture book Ohikkoshi.

Oikawa:

Ohikkoshi is a picture book that doesn’t have a protagonist. There’s not even much of a plot, it’s just about squirrels moving from left to right. (Laughs) I don’t believe that all picture books have to have a protagonist and an ordinary story development. I wanted to try making something a little bit different, or rather, I wanted to challenge the concept of a picture book itself! I remember thinking that as I drew this book.

For example, if you put a whole bunch of acorns into a large colander and then tilt it, the acorns would tumble all over each other, right? When you see that amount of things moving every which way, doesn’t that somehow make you feel happy, or maybe a bit excited? This book also started with that feeling.

I used a thicker pen on purpose to draw the squirrels, so that I wouldn’t be able to add in any realistic-looking details. I thought that it would be more fun that way, since it leaves more room for imagination.

Takeuchi:
At the time, we would receive a request to release a picture book each year from the monthly magazine Ohanashi Pooka, which is handed out in places like kindergartens. This book also came to be through this initiative. Unlike creating a picture book specifically for sale at a bookstore, we had some freedom to challenge ourselves with something experimental. Maybe it’s thanks to this that we were able to make something this daring and bold.

While this picture book is already out of print, I was so happy to hear that nearly 20 years after its creation, it was able to collaborate with the 2026 edition of the Hobonochi Techo. I think the ability to be reborn into a new form like this even after such a long time is so exciting, and perfectly showcases the appeal of picture books.

Please Read Before You Buy

We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.

Press marks or shines may appear on the corners: You may notice press marks, slight whitening, or a glossy finish on the corners of the front and back covers. These are unavoidable results of the binding process.

Color transfer may occur due to friction, pressure, or moisture: Color may transfer to other items through friction or prolonged contact. This risk increases when the cover is exposed to water or sweat, so please take extra care when carrying it near clothing or other belongings.

About the paper used (techo): The Tomoe River paper designed for planners is known for its thinness and smooth writing surface. However, depending on the type and amount of ink or pen used—as well as environmental conditions—some ink may bleed through or take longer to dry. We recommend testing your pens on an inconspicuous area first, or using a pencil board or blotting paper for best results.
