Estimated Shipping Date: 1st Week October 2025
The Jibun Techo Biz 2026 isn’t just a planner—it’s a companion for clarity, growth, and focus. With its sleek matte black cover and refined layout, it’s designed to fit seamlessly into professional and personal life. Built around the concept of “jibun” (myself), every page helps you organize not just your schedule, but also your goals, reflections, and milestones.

The Jibun Techo Biz 2026 B6 Mini Slim combines refined style with practical functionality, designed for professionals and minimalists alike. Its compact size makes it easy to carry while still offering all the thoughtful planning tools of the Biz series.
With its integrated matte cover and pen holder, the Biz planner presents a sleek, monochrome look suitable for any setting. Inside, the simple, elegant color scheme creates a calm atmosphere while writing. The planner also features MIO PAPER—exclusive to the Biz lineup—for smooth, quick-drying, and smudge-resistant writing comfort.
Streamlined & Professional Design
The compact B6 Mini Slim size fits perfectly in bags or on smaller desks, while the integrated matte cover provides durability and understated elegance.
Premium Writing Experience
Crafted with Kokuyo’s original MIO PAPER, thicker than the Standard’s THIN PAPER, this planner is optimized for fountain pen and gel ink users who value smoothness and minimal bleed-through.
Comprehensive Planning Tools
From 3-year calendars and annual schedules to monthly projects and weekly vertical layouts, this planner keeps you on top of both your professional and personal goals. Lists for books, movies, gifts, and goals add depth to your reflections and planning.
Compact Yet Complete
Though smaller than the A5 Slim, the B6 Mini Slim still provides all the essential features, ensuring you never sacrifice functionality for portability.
Product Note: Possibility of smudging or ink bleed-through depending on ink type used.
