Hello, this is Iwasawa from Techo Team.

Today, we’re starting a new series, “Great things about covers and stationery.” Now that we’ve been using our 2025 techo and stationery for a few months, there’s even more we want to share! We want you to know! So, the Techo Team will be sharing what makes each item special.

First up, I’ll be introducing the Masamune Kusano × junaida Weeks, “Through the Purple Night.”



Look at this artwork! It’s a mysterious purple forest, but if you look closely, you’ll spot animals like cats, deer, and horses (even a snail!), along with planets and beautiful flowers, all painted in watercolor. This illustration was originally created for the picture and poetry book “Himitsu Stranger.” The book features stories illustrated by junaida, each inspired by the lyrics of songs written by Masamune Kusano from Spitz’s album “Himitsu Studio.”

When I first heard about the book’s release, I felt excited to see a collaboration between Spitz and junaida, two of my favorite artists.


Right: The illustrated songbook “Himitsu Stranger.” It’s a little worn from being read so much.

And when I finally saw the book, all I could say was, “Whoa… this is amazing.” Seeing the lyrics in visual form made the songs feel even bigger. I’d listen to the album while flipping through the book, or just enjoy the songs on their own, or get lost in the artwork by itself. Every time I looked or listened, I’d find something new that made my heart race.

And now, the title illustration for “Through the Purple Night” from that book has become the cover of this Weeks. The artwork is printed on a fabric cover that feels like canvas, so you can carry a piece of that book’s world with you every day.


You can really see the brushstrokes of the watercolor painting.

I asked Hoshino, who’s been using this techo for work every day, what she thinks of it.



“I’ve always loved “Through the Purple Night” as a song, and I like how just catching a glimpse of it while working gives me a little boost of courage. This Weeks also comes with a matching pencil board, so I love that I can have more of its world with me when I use my techo.”


Always by Hoshino’s computer.

Yes! This Weeks comes with an original pencil board, too.


The design of the pencil board set: the front is on the left, and the back is on the right.

We didn’t just want to stop at the cover; we wanted you to experience more of junaida’s artwork. So, we went all in and made it a set. The pencil board design is taken from the book’s illustrations, bringing you even closer to the song’s world. This beautiful Weeks feels like an invitation to a new world. I hope you’ll enjoy it with its special pencil board!
