  • 2026 New

Shirt Fabric is a series of items created with comfortable fabric produced for clothing like shirts. This year, we present you with a Weeks made with a muted plaid fabric.



As this is a fabric made for use in clothes, it’s a 100% cotton material and feels smooth to the touch.



The basic color scheme of gray and brown make for a sophisticated plaid pattern, and the subtle lines woven into the fabric give it a chic and soft impression.









The year 2026 is pressed in gold foil.



A Weeks in a smoky plaid pattern that is great for everyday use, but also appropriate for business environments, making it the perfect companion for any occasion.





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.

Press marks or shines may appear on the corners

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.
