The Jibun Techo DAYs ("jibun" meaning "self" in Japanese) was designed around a specific problem: most planners force you to collapse everything into a single timeline, mixing work and personal life, to-dos and appointments, into one undifferentiated block.

The DAYs format solves this by placing a 24-hour time axis at the center of each daily page and sectioning the surrounding space so that different types of information stay separate. "To Do and Schedule" lives in one column; "Business and Private" logs occupy another. Nothing bleeds into everything else.

This 2027 limited edition pairs that structure with a cover illustrated by Seiji Matsumoto, whose sheep pattern appears across both the blue and yellow colorways. The PVC cover has a transparent matte finish and includes a built-in pen holder, so the diary travels as a self-contained unit.
