The song-art book Himitsu Stranger is based on the lyrics from 13 songs recorded by Masamune Kusano for the music album “Himitsu Studio” by his rock band Spitz. Artist junaida illustrated the lyrical stories for each of the songs. Inside the book is an illustration called Through the Purple Night, which was then chosen for this Weeks book cover.



Through the Purple Night was actually the first illustration junaida did among everything in the song-art book. It shows a forest enveloped in purple, with birds, cats, and other small animals, as well as trees, flowers, and other cute plants, topped off with some planets and other things. This really completes the look as the all-over print recreates this artwork and its unique floating feeling.







The cover material is a rough, textured canvas and the cover is a hardcover with a slight bend to it. The base color is the same white as featured in the original song-art book.







The cover and spine have the year 2025 foil-printed in gold for a simple, refreshing look.







This techo also includes a pencil board with Through the Purple Night. The front side has a scene that stirs the imagination, while the back shows details that really highlight the texture of junaida’s watercolor paintings.







Pair it with the techo to immerse yourself in the world of junaida’s art.







The song-art book Himitsu Stranger that this cover is based on is also for sale in the Hobonichi Store so you can experience the rich blend of lyrics with illustrated narratives.

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.







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.
