Naoki IshikawaDenali in the Midnight Sun #1Weeks Hardcover Book / Weekly Horizontal / ENG or JPN edition / Jan start / Mon start

  • 2025 New

This Weeks book features a photograph of Denali, North America’s highest peak, as taken by Naoki Ishikawa.



This photo, capturing the full extent of Mount Denali at 6,190 meters above sea level, was taken from inside a Cessna heading towards base camp for the summit. The view of the mountain composed of deep blue and white looks like a watercolor painting at a glance. This photograph is processed with cyanotype, which is a photographic process that involves a chemical solution and exposure to UV light. The appeal in this design comes from the brush marks that let you see where the solution was applied.



In 2016, Ishikawa climbed Denali all by himself. During a season close to the midnight sun, he diligently kept climbing while bathed in the sunlight, amidst the blue and white landscape. He depicted that scenery more impressively in Denali in the Midnight Sun #1.



The photograph is fully printed in this Weeks book. You will be able to have the vast landscape of Denali always by your side. The year 2025 is foil-pressed in silver.







The back has the name of the piece and the photographer foil-pressed in silver.







Seeing the great scenery with the blue mountain and sky against the white snow and clouds will motivate you whenever it catches your eyes.

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. This paper that underwent an overhaul with the 2024 edition techo is more resistant to bleed through, lighter despite being the same thickness, and has a smoother surface by adjusting the fibers of the paper.







The Weeks book has space for writing in plans or journal entries, and it also has 69 pages of grid paper memo pages in the back (73 pages in the English edition). The back of the book contains bonus pages, including Sample Symbols and Icons and Oodles of Noodles.







The Hobonichi Techo 2025 Weeks book comes in either English or Japanese. If you love this cover, then you can pick out which language you’d like in that book.

*The English edition book only comes as the January-start version.







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.

Turning a photo that almost looks like a watercolor painting into a techo cover

When I was thinking of creating a techo cover featuring a photograph, I was reminded of the “Himalaya” cover featuring Naoki Ishikawa’s photograph from the Hobonichi Techo 2015 lineup. I wondered how I can make a cover where you can feel the vast nature like that cover, but with a different touch.



As I went through Ishikawa’s photographs, I was drawn to this photo using cyanotype. With the blue base and a look like a watercolor painting, I thought it would be refreshing to use this photograph as a techo cover.



Cyanotype uses a chemical solution and exposes it to UV light, so you can see the brush marks in the piece. I loved how it looked and decided to print those brush marks onto the cover as well.



I hope you carry around your techo cover as if always keeping a beautiful piece of art with you by your side.

Please Read Before You Buy

In order to provide you with the most satisfaction for your product, we've compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Please be sure to read this information carefully before placing your order.

Test fountain pens before regular use

The Hobonichi Techo's Tomoe River paper is designed to prevent bleed-through, but some fountain pens and water-based ink pens are not compatible with this paper. When switching to a new pen, we recommend testing the pen somewhere in the book, such as the back memo pages, to see if the ink bleeds through or takes an especially long time to dry.

Cover corners are slightly bumpy and shiny

The corners of the cover contain light traces of press marks, shines, and lumps. This is an unavoidable part of the manufacturing process.

Imprinted year numbers may peel

The numbers of the year are stamped onto the cover in metallic or other colored leaf, so strong rubbing or everyday use may cause the numbers to peel off.

Avoid storing in hot and humid places

Please avoid storing your product in hot, humid places or placing it atop other objects for long periods of time as this may result in lower quality and color stains.

Avoid using with Clear Cover

This cover uses thicker materials than usual, so it may not fit. Forcing it into a Clear Cover may damage the product.
