Koupen-chan Hanamaru Life! [2026]
“Koupen-chan Hanamaru Life” was a large pop-up event in Tokyo Station that took place from February 20th to March 5th, 2026. Tokyo Station, including Character Street and First Avenue, was adorned with large wall-to-wall posters, balloons, floor decals, and even photograph standees.
I believe there was also an additional Koupen-chan pop-up store to supplement the existing Hanamaru Station store in Character Street.

C: Introducing FABER-CASTEL x Koupen-chan Watercolor Pencils ✨
I’ve also been relying on these colored pencils for a long time now 🍀
I strongly recommend them!
The first pack is a set of 36 colored pencils I’ve been using since a young age. I enjoy how the colors run when moistened with a watercolor brush.
The second pack is a set of 120 colored pencils. This set played a large part in the making of “A Koupen-chan Picture Book: A Stroll with the Sea.” Even now, I use them for daily Koupen-chan illustrations. This treasured 120 colored pencil set is a dream come true, made possible by everyone’s support in buying my books and goods. Truly, thank you so much. I will carefully use them until the lead is no more!
