Behind the Design

Most diary covers flex and bow under pen pressure the moment you step away from a desk. MIDORI's Flat Diary addresses this with a foamed PP cover: a material that keeps the book rigid enough to write against while staying noticeably lighter than standard hard covers. The spine is constructed to open completely flat, which matters with a monthly block layout because the grid spans both pages and any curve in the binding interrupts the dates at the center fold.

The file-style features built into the cover reflect how the diary is actually used in motion. The left inner slit fits a business card or doubles as a bookmark so the diary opens to the current month without flipping. The right pocket holds documents for reference during meetings or events. The A4 version accepts unfolded A4 sheets and folds down A3 documents, which positions it closer to a portable document wallet than a conventional planner.

A separate diary refill is available in both A5 and A4, so the cover can carry over to the next year.

A monthly block diary with a foamed PP cover that opens completely flat, so writing feels like filling in a wall calendar. The cover is rigid enough to write on while standing, and both A4 and A5 sizes include a document pocket and business card slit built into the cover.
