Japan’s Stationery Makers Launch First Collaboration! Campus × Rollbahn

Hello, I’m Hakoboya, the Souvenir Promotion Captain for Kodawari Times! ╭(·ᴗ·)╮╰(·ᴗ·)╯
Stationery is a popular item for souvenirs from Japan. Japanese-made stationery is known for its high quality, durability, comfortable feel, and rich variety of designs.
This time, a Japanese stationery maker has released its first-ever collaboration item. Check out the limited-edition collab between Japan’s iconic notebook “Campus” and the ring memo pad “Rollbahn”.

 

Two of Japan’s leading stationery brands

This time, two famous Japanese stationery brands announced a collaboration product.
KOKUYO CO.,LTD. (Headquarters: Osaka City) has the “Campus Notebook” as its staple product, celebrating its 50th anniversary in 2025. It’s an essential item in Japanese learning environments that every student in Japan has used at least once.
Meanwhile, DELFONICS Co.,Ltd. (Headquarters: Tokyo) features the stationery brand “Rollbahn,” which will celebrate its 25th anniversary in 2026. The brand name means “runway” in German, and these items combine design and functionality as memos for freely jotting down daily thoughts and notes.

The moment when two stationery brands’ anniversaries intersect has been captured in the first-ever collaboration items from Campus × Rollbahn. The “intersecting moment” of Campus Notebook and Rollbahn’s anniversaries is expressed in two forms: a “design exchange notebook” and a “collaboration limited edition design.” Be sure to check out this collaboration product that’s also drawing huge attention from Japanese fans.

 

Design Exchange Notebook

Based on the standard models of Campus Notebooks and Rollbahn Pocket Memo, we’ve replaced not just the cover design but also the specifications, inner paper, and even the ruling lines. This lets you rediscover the “differences” from the originals and savor the unique “character” of each one.

Campus × Rollbahn Ring Memo L

KOKUYO has released a ring memo pad based on the standard Rollbahn Pocket Memo L, featuring the Rollbahn logo and Campus-style inner paper. The color lineup includes three shades: Dark Blue, Yellow, and Light Blue.
It adopts the two most standard Rollbahn colors—Dark Blue and Yellow—along with Light Blue, the cover color of Campus notebooks with B-ruled lines.

Manufacturer’s Suggested Retail Price (excluding tax): ¥900

Campus × Rollbahn B6 Notebook

The cover design of the Campus Notebook, featuring wireless binding and writing space while balancing functionality and style, remains unchanged from Rollbahn, with only the Rollbahn logo replaced.
The pages are bound using “Rollbahn Special Paper,” a high-quality 5mm grid paper that resists ink bleeding and show-through. Its compact B6 size is nearly identical to a mini tablet, making it extremely portable. Perfect for important notes and daily journaling.
The color lineup includes three options: Campus Notebook’s classic Light Pink and Light Blue, plus Rollbahn’s signature Dark Blue.

Price (tax not included): ¥430 each

 

Collaboration Limited Edition Design

The shared motif is a “place connecting to the sky,” blending the ‘school’ meaning of Campus with the atmosphere and scenery of Rollbahn’s “runway.” Limited-edition design items are released from both brands. With so many different items available, you’ll be spoiled for choice. Don’t miss out on these exclusive designs available only for a limited time!
