What is the Midori Business Diary A5 Monthly?
It is a thick A5 diary with a month on each spread and room to write the day against a clock. Midori, the Japanese stationery maker, calls the layout monthly horizontal and says it was formerly coded AM-2. Its store text sells it as a reliable partner for business use, with a lot of memo space.
The monthly pages let you glance at a whole month, while the hourly lines let you log how a single day runs. For a lighter, stiff-cover monthly book, see our Midori Flat Diary 2027.
What dates and pages does it have?
It runs 16 months from December 2026 to March 2028 in 162 pages. January to December get a spread each, while the last three months, January to March 2028, get one page apiece. Midori lists 29 monthly pages, 123 plan-memo pages and 4 address pages, plus an annual calendar, a short calendar, an annual plan and a personal memo, with rokuyo shown.
How does a day work on the monthly page?
Each day is a time-ruled strip from 7:00 to 20:00. Midori says the layout lets you write the day’s events in time order, and a memo space at the right edge takes To Dos or the day’s main task.
Midori swapped reference tables for free memo pages. The list it dropped includes subway maps for Tokyo, Osaka, Kyoto and Nagoya, a world map, city population and area-code tables, a telephone and website list, conversion tables, postal rates, stamp-duty tables, interest conversion and a year-and-age chart. Midori says digital tools cover these now, so the pages became plain memo space.
How big is it?
The body is 216 × 157 × 12 mm and about 310 g. The paper block inside is 210 × 148 mm, which is A5. See our paper sizes guide for the standard sizes.

Who is it for?
Midori pitches it at people who keep a business calendar and a lot of notes together. With 123 memo pages beside the monthly spreads, it works as a meeting notebook as well as a diary. The trade-off is bulk: at 12 mm and about 310 g it is much thicker than the slim monthly books in the same line.
The time-ruled strip suits people who book the day in hours, such as appointments from 7:00 to 20:00. If you don’t plan by the hour, a plain monthly block, like the one in the Midori MD Diary 2027, leaves more room for notes per day.
Midori’s store lists Japan as the country of origin. The diary costs 1,540 yen (about US$9.75) with tax at 158 yen to the dollar, which puts it in our $$ band ($5–20).
