It is a monthly-only diary, so there are no daily pages. For one page per day, see our [Midori MD Diary 2027](https://stationerytimes.com/guides/midori-md-diary-2027/). For the paper, see the [Midori MD system guide](https://stationerytimes.com/guides/midori-md-system-guide/). ## What dates and pages does it have? **It starts in October 2026 and runs 16 months to January 2028, in 36 pages.** Midori's store lists an annual calendar and a monthly schedule, with rokuyo shown. Its holidays follow the official gazette published on February 2, 2026, and Midori warns they may change if the law does. The store also says there are no April-start, September-start or Sunday-start versions and none are planned, so if you need one of those, look at another diary such as the [KOKUYO Campus Diary Monthly 2027](https://stationerytimes.com/guides/kokuyo-campus-diary-monthly-2027/). ## What does a month look like? **Each month has a ruled monthly block, a wide grid memo area and a vertical calendar.** Midori says the block lets you manage each day, the memo area takes to-dos or sticky notes stuck straight on, and the vertical calendar tracks long plans. The pages are white MD Paper. ## What sizes, weights and colors are there? **A5 and A4, each in black or white.** Midori's store gives the following. | | A5 | A4 | |---|---|---| | Body size | 225 × 162 × 10 mm (8.9 × 6.4 × 0.4 in) | 313 × 223 × 10 mm (12.3 × 8.8 × 0.4 in) | | Weight with packaging | About 150 g | About 301 g | | Tax-included price | 1,320 yen (about US$8.35) | 1,540 yen (about US$9.75) | Prices are Japanese prices at 158 yen to the dollar. The A5 weighs about half the A4. ## What are the cover and pocket like? **The cover is foam polypropylene with a hairline finish, light and stiff like a clipboard.** A slit at the lower left holds a business card or the corner of a page as a bookmark, and an inside pocket on the right takes loose documents. Midori says the A5's pocket fits an A4 sheet folded in two. ![A black A5 diary outline with a folded A4 sheet shown inside it](https://stationerytimes.com/images/midori-flat-diary-2027-pocket.svg?v=4032ecd5) *A folded A4 sheet against the A5 outline at 1 mm = 1 px; the pocket position is drawn by eye. Original illustration made for this guide. © Stationery Times.* ## Who is it for? **Midori recommends it for seminars, events, job-hunting students and office workers.** Its store text also mentions carrying a diary for remote work and working in tight spaces, where a thin, light book helps. Because the cover is stiff and the pocket holds papers, it suits people who carry handouts with their schedule. The trade-off is that a monthly block gives less room per day than a weekly or daily book.

An A4 refill is listed too. ## Where is it made, and what does it cost? **Midori's store lists Japan as the country of origin.** The A5 costs 1,320 yen (about US$8.35) and the A4 1,540 yen (about US$9.75) with tax, which puts both in our $$ band ($5–20). For two calendars in one B6 book, see the [Midori Double Schedule Diary 2027](https://stationerytimes.com/guides/midori-double-schedule-diary-2027/); for the thick A5 business book, the [Midori Business Diary A5 Monthly 2027](https://stationerytimes.com/guides/midori-business-diary-a5-monthly-2027/). ## Frequently asked questions ### What months does the Midori Flat Diary 2027 cover? 16 months, October 2026 to January 2028, per Midori's store.
