Masamune Kusano x junaidaHimitsu StrangerA6 Original Size
- 2025 New
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. This techo cover is packed with all the charm of Himitsu Stranger as it features an all-over print of the illustrations on the front cover of the special book.
The array of strange characters and items are all straight from the book and were drawn in response to Kusano’s suggestion to draw them in a deformed style.
It’s fun to look through all the images and let your mind wander as you wonder about the story behind each character and in which scene each item appeared.
In order to retain the vibrant colors of the original art, the cover is made with a fine-grain polyester material that’s velvety and smooth to the touch. 
The back of the cover also has illustrations hidden inside the pocket. Peek inside and you’ll get a glance at art that’s different from that on the outside. 
The cover interior is printed with pencil drawings from the book. From the various stories within the book, you can see recreations of the kind of scenes that go along with what it’s like to use the techo every day, such as scenes from everyday life, the passage of seasons and time, and a broad range of emotions. 
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. 
In the Hobonichi Techo 2025 lineup, the Original book comes in either English or Japanese.
*The English book is only available as the January-start version.

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.
- Actual specifications may vary from listing
Each item is individually assembled and sewn by hand by a factory worker. Best efforts are made to ensure consistent sizes and specifications, but there may be slight differences.
- Color and print may vary slightly
This material is first printed or dyed and then later sewn onto the cover. While colors are designed to be consistent, there may be uneven coloring or slight shade variances between covers. This may also happen across a single cover, such as a pocket compared to the rest of the cover. In addition, on rare occasions, there may be small black or white dots visible on the print. This is an unavoidable aspect of the manufacturing process.
- Cover may contain variations in stitching or loose lining
Due to the structure of the cover that opens flat 180 degrees, exterior stitching areas may appear puckered and lining material may be loose.
- Pen holders are rigid at first
The pen holders are rigid at first, making it difficult to insert pens. You can speed up the breaking-in process by rolling the pen holders in your hand.
- Pen holder fits pens up to 13.5 mm wide
The pen holder is designed to perfectly fit the 12.2 mm (0.48”) diameter Jetstream pen offered as a free Hobonichi Store Exclusive. Pens with certain shapes and materials may be difficult to pull through the holder. The holder can fit pens up to 13.5 mm (0.53”) in diameter.
- 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.
