What is the Midori Yuru Log Free Monthly Diary?
It is an undated B6 notebook that combines a monthly diary with grid memo pages, built to be decorated. Midori, the Japanese stationery maker, sells it in its Yuru Log series, a line of notebooks, stickers and stamps meant for keeping a light, enjoyable record of each day.
Its store text says the monthly block is simple on purpose so that stamps and stickers can carry the design. That makes it a different tool from a dated diary: you add the month, then decorate it. For a notebook with a 3 mm grid for drawing your own calendar, see the Maruman Septcouleur notebook.
What pages does it have?
48 pages: 12 months of monthly schedule and 23 pages of 2 mm grid memo. The diary is undated, so you can start on any day. The grid is a faint, restrained design that Midori says stays out of the way of stamp patterns, acting as a guide for writing, drawing and for placing stickers and photos.
Thick MD Paper, thread-sewn so the book lies flat. Midori’s store says the thick MD Paper resists ink show-through from stamps, which is why it recommends the notebook for stamp arrangements. The flat opening matters for stamping, since Midori says the binding was chosen for a good stamping feel.
How big is it?
Midori lists the body as 182 × 123 × 6 mm, in a B6 format. The package, including a clear polypropylene cover, is 186 × 125 × 6 mm. Midori’s store lists no weight. Our paper sizes guide explains the B series.
How would you use it?
Treat each month as a blank calendar and fill it with a stamp, a sticker or a line. Midori’s store describes pressing a stamp on an ordinary day or a special one, and using stamps to build your own format. Because the diary is undated, you can number the days yourself, skip months you don’t need and start the year whenever you like.
The grid pages suit longer notes, lists, drawings and pasted photos. We haven’t tested the notebook, so we can’t say how it holds up under markers or wet ink, and Midori’s page doesn’t rate it for fountain pens. For more on the paper used across Midori’s notebooks, see our Midori MD system guide.
Which stickers and stamps go with it?
Midori’s Yuru Log series has several sticker types and a stamp line. The store names stickers you can write on with a water-based pen, stickers that decorate the record, stickers that color the margin and correction stickers that hide mistakes, and stamps for marking each day. Our Midori Yuru Log stickers guide covers the stickers in detail. For a calendar sticker that turns any notebook into a monthly planner, see the STALOGY Removable Seal Calendar.
Where is it made, and what does it cost?
Midori’s store lists Japan as the country of origin. The notebook costs 1,078 yen (about US$6.82) with tax at 158 yen to the dollar, which puts it in our $$ band ($5–20).
