Arts＆ScienceMatte ShrinkA6 Original Size
- 2026 New
- HOBONICHI STORE ONLY
This Hobonichi Techo cover was created in collaboration with ARTS & SCIENCE, the shop and brand led by Sonya Park, who also directs the English-language edition of the Hobonichi Techo, the Hobonichi Techo Planner.
This year’s selection features matte shrink leather—chrome-tanned cowhide embossed with a natural shrink texture. The matte finish lends the leather a sense of refined elegance.
What makes this cover particularly striking is its pure white color. The leather is first dyed with pigment to create a vibrant base, then finished with surface dyeing to achieve its beautiful tone. The design has been kept simple and sophisticated to allow the clarity of the color to shine through.
The finely textured surface creates subtle shadows and adds depth. The leather is soft and smooth to the touch and becomes more supple as it adapts to your hand over time.
Each of the four corners inside the cover features a rounded slit to securely hold your techo. These soft curves add a touch of grace to the minimal design.
Silver-foil stamped logos for Arts&Science and Hobonichi appear along the slit. You can also use the slits to tuck in cards and small papers.
It has a pen hook designed to hold a pen by its clip.
Each pen hook is hand-stitched, adding a natural, artisanal touch to the design.
The bookmark is made from the same leather as the cover and features a simple, understated design.
The Planner is an English-language techo directed by Sonya Park, designed with thoughtful features unique to this edition—including bonus pages not found in other versions.
The Hobonichi Techo leather covers are made with all-natural materials that have their own unique appearance. Every leather cover is a one-of-a-kind, all-natural product, so you can feel good knowing your cover is the only one like it in the world. Here are some of the unique characteristics you can expect to find.
- Markings that naturally occur during an animal’s life:
Wrinkles, veins, texture, and scratches
- Characteristics from the manufacturing process of natural leather:
Dark spots (occurs when components of the leather are exposed to iron in the air during the tanning and dyeing process)
Please note:
White leather will naturally yellow over time, but this change will not significantly affect the overall character or texture of the cover.

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.
- About the pen hook
The pen hook of this cover is designed to hold a pen by its clip.
- Leather may contain preexisting wrinkles and marks
In order to allow customers the enjoyment of all-natural leather, the leather is processed in a way that retains its original feel. This may leave imperfections visible on the surface of the cover, such as wrinkles, scratches, stains, or vein marks.
Depending on the conditions in which the cover is used, natural oils of the leather may emerge and appear as stains. We ask for your understanding for these naturally-occurring characteristics of genuine leather.
- Each leather piece has a unique look
This product uses leather with a highly distinctive character. The appearance of the leather varies depending on which part of the hide is used, so each item will have a one-of-a-kind expression. Please note that the pattern or texture may differ from what is shown in the product images.
- 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.
