KOKUYO describes the contents as an annual calendar, a fiscal-year planner and the monthly schedule. Its own wording says the one-month block spread suits people who keep a digital calendar and want a paper overview beside it. ## What sizes does it come in? **Four sizes, from pocket to desk.** KOKUYO names the sizes by paper standard rather than millimeters, so the drawings below use the standard A and B6 dimensions. | Size | Sheets | List price before tax | |---|---|---| | A6 | 32 (64 pages) | 500 yen (about US$3.16) | | B6 | 32 (64 pages) | 540 yen (about US$3.42) | | A5 | 32 (64 pages) | 560 yen (about US$3.54) | | Semi B5 | 32 (64 pages) | 640 yen (about US$4.05) | Our [paper sizes](https://stationerytimes.com/guides/paper-sizes-explained/) guide explains the A and B series. KOKUYO's pages don't give the Semi B5 dimensions, so we don't draw it here. ## What colors and layouts are there? **The standard covers are blue and pink, plus limited-edition designs in A6, B6 and A5.** The A5 is also made as a grid-ruled monthly in black, green and red. That version has a grid in the schedule area so you can split a day into several entries. ![Three schematic pages: a monthly block of day boxes, a weekly page with day rows and a memo column, and a weekly page with day columns and an hourly timeline](https://stationerytimes.com/images/kokuyo-campus-diary-monthly-2027-layouts.svg?v=ef2f6a52) *The three Campus Diary layouts KOKUYO lists, drawn by eye from its descriptions. Original illustration made for this guide. © Stationery Times.* ## What do the dates cover? **The January start runs from December of the previous year to January of the following year, per KOKUYO.** For the 2027 edition that is 14 months, which lets you plan the last month of 2026 and carry one month over into 2028. KOKUYO's page warns that holidays and event days may change when laws such as the Public Holidays Act are revised. ## What about the weekly Campus Diary? **KOKUYO also sells weekly books in A5 and Semi B5 with 56 sheets, or 112 pages.** The horizontal type gives each week a spread with room for notes, and the vertical type adds an hourly timeline for scheduling a day by time. They cost 1,070 yen (about US$6.77) in A5 and 1,180 yen (about US$7.47) in Semi B5 before tax, which places them in our $$ band ($5–20). For a monthly book with more room, see our [Leuchtturm1917 Monthly Planner](https://stationerytimes.com/guides/leuchtturm1917-monthly-planner-2027/); for a three-in-one diary with weekly timelines, see the [KOKUYO Jibun Techo Diary 2027](https://stationerytimes.com/guides/kokuyo-jibun-techo-diary-2027/). ## How does it compare with the rest of the Campus range? **KOKUYO calls the monthly type thin and light; the Campus notebook and ring-binder lines cover other jobs.** Our [KOKUYO Campus notebook](https://stationerytimes.com/guides/kokuyo-campus-notebook/) guide covers the ruled notebooks, and the [Campus Smart Ring binder](https://stationerytimes.com/guides/kokuyo-campus-smart-ring-binder/) covers the loose-leaf option. KOKUYO's pages list "scheduled to end while stocks last," so check stock before choosing a size. ## Where is it made, and what does it cost? **KOKUYO's English pages don't say where it is made; they list the maker only.** Its list prices run from 500 yen (about US$3.16) to 640 yen (about US$4.05) before Japanese consumption tax at 158 yen to the dollar, which puts the monthly diaries in our $ band (under $5). ## Frequently asked questions ### How many pages does the Campus Diary Monthly have? 32 sheets, which is 64 pages, in every monthly size and layout KOKUYO lists.
