Jibun Techo, which translates loosely as "planner for yourself," was developed by KOKUYO around the idea that a single diary format rarely fits the full range of things people want to track. The First Kit bundles three booklets into one PVC cover to address that directly.

The DIARY booklet handles day-to-day scheduling with both monthly block and weekly vertical layouts. The LIFE booklet uses MIO PAPER, a thinner stock suited to long-term archiving, and is designed for entries that don't belong to a single year: places visited, milestones, things worth keeping. The IDEA booklet is a grid memo pad for notes and sketches that don't fit a dated page.

The cover's transparent matte PVC keeps all three booklets in a single unit while letting the color of each spine show through. The built-in pen holder and bundled ruler with rubber band close out the system without requiring add-ons.
