Capture the Essence of Spring: Rollbahn’s New Diaries Embrace Personal Storytelling
DELFONICS, a prominent Japanese stationery brand, is preparing to unveil its 2026 March-start Rollbahn Diaries, a collection meticulously crafted to accompany individuals through their spring-to-spring journey. Set for release on February 6, 2026, at DELFONICS and Smith direct stores, with a staggered launch at national retailers from late January, this collection boasts an impressive 287 variations, ensuring a perfect match for every personality and purpose.

These diaries, designed to cover March 2026 through April 2027, are particularly suited for students, whose academic year traditionally begins in April in Japan. They offer a fresh start, inviting users to record their academic pursuits, personal growth, and everyday inspirations in a format that encourages self-reflection and creativity.
“Moment Journal” Campaign: A New Way to Document Life
Central to the 2026 Spring collection is the “Moment Journal” campaign, an innovative concept that encourages users to pair casual smartphone photos with “a word they felt in that moment.” This approach transforms the diary from a mere scheduler into a canvas for personal narrative, blending visual memories with immediate emotional responses.

To give enthusiasts an early glimpse, DELFONICS will host exclusive, reservation-only pre-sales events in two major cities:
-
Osaka: DELFONICS Osaka Gallery, January 23 (Friday) – February 4 (Wednesday), 2026
-
Tokyo: Smith Otemachi Event Space, January 30 (Friday) – February 4 (Wednesday), 2026
These events provide a unique opportunity to physically interact with the entire 287-item lineup before the official launch. Further details regarding reservations, event times, and entry methods will be announced via the DELFONICS Diary Store website.
DELFONICS: A Legacy of Thoughtful Design
Since its inception in 1987, DELFONICS has championed a distinct approach to stationery, beginning with its free-style diaries. At a time when Japanese diaries leaned heavily into functionality and imported options were often overtly pop, DELFONICS sought a universal, warm simplicity reminiscent of European design. This philosophy led to their diaries becoming a hallmark product, continually refined and redesigned each year.
Prices for the 2026 March-start Rollbahn Diaries will range from 737 yen to 2,255 yen (tax included). The DELFONICS Web Shop will commence sales at 11:30 JST on the launch day. For the latest updates on designs, limited-edition items, pre-sale reservations, and related accessories and workshops, followers are encouraged to check the dedicated DELFONICS Diary SNS accounts.
As the brand’s “Diary Team” articulates, “The act of writing. A diary is a tool that creates richness of heart.” This ethos underscores their commitment to fostering mental well-being and self-expression through their products.
Embrace Your Unique Narrative
With the upcoming launch, the Rollbahn Diary invites individuals to embark on a new year of self-discovery and personal documentation. Whether for academic planning, creative journaling, or simply capturing daily thoughts, these diaries offer a tangible space to cultivate one’s own story. As DELFONICS continues its tradition of blending practicality with aesthetic appeal, the 2026 Spring collection stands as a testament to the enduring power of putting pen to paper, fostering creativity and a deeper connection to one’s experiences.
