The Kokuyo Jibun Techo First Kit 2026 in A5 Slim is the ideal entry point into the Jibun Techo system. More than just a planner, it’s a three-part framework designed to help you manage today, preserve yesterday, and plan for tomorrow. The set includes three specialised notebooks: DIARY for scheduling and projects, LIFE for milestones and memories, and IDEA for notes and creativity.

Crafted with Kokuyo’s premium papers—THIN PAPER™ in the DIARY for light, everyday use and MIO PAPER™ in the LIFE notebook for archival quality—you’ll enjoy smooth, fountain pen–friendly writing across all volumes. The A5 Slim format balances portability with generous writing space, while thoughtful details such as lay-flat binding, colour-coded monthly tabs, a transparent cover with pen holder, and minimalist Japanese design make this set as functional as it is elegant.
