## What is the Hobonichi Techo Cousin avec 2027?

**The Cousin avec is Hobonichi's A5 planner split into two half-year books, with daily, weekly and monthly pages in each.** Book 1 runs January to June in a lime yellow cover; book 2 runs July to December in ice blue.

Hobonichi says the layout matches the one-book [Hobonichi Cousin](https://stationerytimes.com/guides/hobonichi-cousin/), apart from calendar ranges and the number of bonus pages. You get the A5 Cousin's big daily page and its vertical weekly pages, at roughly half the weight per book.

![Timeline of the Cousin avec 2027 books: monthly, weekly and daily date ranges of book 1 and book 2](https://stationerytimes.com/images/hobonichi-techo-cousin-avec-2027-contents.svg)

*The two books overlap at the handover, so June and July plans fit in either.*

## How heavy is the Cousin compared with the avec?

**Each Cousin avec book weighs about 260 g, against about 445 g for the one-book 2027 Cousin, per Hobonichi.** The one-book Cousin is 18 mm thick; each avec book is 10 mm.

The pair together weighs more than one Cousin, because each book repeats the yearly pages, monthly calendars and bonus pages. The gain is what you carry on any given day.


## What do the weekly pages look like?

**Each weekly spread lays the seven days out in vertical columns against a time axis, Monday first.** Hunter Paper Co. notes that the weekly pages include a time schedule, which makes them good for appointments, while the daily pages hold notes, diaries and pasted tickets.

The weekly spreads run a few days past each half-year, so book 2 starts with the last week of June. The Original avec has no weekly pages at all; that is the main reason to choose the Cousin version.

## Cousin avec or Original avec: which should you choose?

**Choose the Cousin avec for room and weekly planning, and the [Original avec](https://stationerytimes.com/guides/hobonichi-techo-original-avec-2027/) for a pocketable A6 book.**

| | Cousin avec 2027 | Original avec 2027 |
|---|---|---|
| Size per book | 210 × 148 × 10 mm | 148 × 105 × 8 mm |
| Weight per book | About 260 g | About 110 g |
| Pages per book | 288 | 240 |
| Weekly pages | Yes, vertical | No |
| Price (Japan, pair) | ¥5,170 (about US$33) | ¥3,080 (about US$19) |

Both use the same Tomoe River paper and 3.7 mm grid. See our [Hobonichi lineup guide](https://stationerytimes.com/guides/hobonichi-techo-lineup-explained/) for the Weeks, Day-Free and HON. For an A5 weekly-block planner built around Japan's seasonal calendar, see the [Koyomi Seikatsu Techo](https://stationerytimes.com/guides/koyomi-seikatsu-techo/).

## Which cover fits the Cousin avec?

**Any Cousin (A5) Hobonichi cover fits each avec book.** Hobonichi says avec books take the same covers as the regular editions, and at 10 mm instead of 18 mm each book leaves more room in the cover's pockets.

## Where is the Hobonichi Cousin avec made?

**Hunter Paper Co. lists the 2027 Cousin avec books as made in Japan.** Hobonichi's store page doesn't name the country of manufacture for the books. Hobonichi is based in Tokyo; for more on the paper, read our [Tomoe River paper](https://stationerytimes.com/guides/tomoe-river-paper/) guide.

## Frequently asked questions

### How much does a Cousin avec book weigh?

About 260 g each, per Hobonichi's Japanese store. The one-book 2027 Cousin weighs about 445 g, so you carry a little over half the weight.

### Does the Cousin avec have weekly pages?

Yes. Each book has 54 vertical weekly pages: book 1 from December 28, 2026 to July 4, 2027 and book 2 from June 28, 2027 to January 2, 2028.

### Is there an English Cousin avec?

Not for 2027. Hobonichi sells the Cousin avec as a Japanese edition; the one-book Cousin comes in English.

### Will my Cousin cover fit the avec books?

Yes. Hobonichi says avec books take the same covers as the regular editions, and each Cousin avec book is the same A5 size, only thinner.

### What grid size is the Hobonichi Cousin?

3.7 mm, per Hobonichi's spec table for the Cousin avec, the same grid as the Original.

### Why buy the Cousin avec instead of the Original avec?

For space and weekly planning: the Cousin avec pages are A5, twice the area of A6, and it adds vertical weekly pages that the Original avec lacks.

### Is the Hobonichi Cousin avec made in the USA?

No, in Japan, per Hunter Paper Co.'s 2027 listing. Hobonichi doesn't name the country on its store page.
