## What is the Nanami Seven Seas Crossfield?

**It's a thick A5 journal of very thin Tomoe River paper, made for fountain pen users by Nanami Paper of California.** Seven Seas is the name Nanami uses for the notebooks it designs; the Crossfield is the version printed with a cross grid.

Nanami's design notes ask for three things: a sewn binding, a thin flexible cover trimmed flush with the pages, and a high page count. There's no printing on the cover, and the Nanami name appears only on the back end sheet.

The Crossfield has a long following among pen bloggers. Mountain of Ink called it "my favorite notebook of all time" in 2017, and The Well-Appointed Desk has used one for ink swatches since 2017.

## Nanami Crossfield specs

| Spec | Seven Seas Crossfield (8th edition) |
|---|---|
| Size | 210 × 148 mm (8.3 × 5.8 in), A5 |
| Thickness | 16 mm (0.7 in) |
| Pages | 480 (240 leaves) |
| Paper | 52 gsm Tomoe River, white (off-white); Sanzen paper made before July 2024 |
| Ruling | 5 mm cross grid of 2 mm gray crosses |
| Binding | Smythe-sewn (thread-bound), lays flat |
| Cover | Thin, flexible, water-resistant coated fabric |
| Extras | Rounded corners, ivory end sheets, one A5 blotter sheet, kraft slip case |
| Made in | Japan (Tokyo) |

All figures come from Nanami's product page. Its Seven Seas fact page describes the cover as buckram, a treated library-binding fabric, and gives the thickness as 15 mm for the lined Writer version.

## What does the cross grid look like?

**Each page carries small gray crosses about 2 mm across, set 5 mm apart, instead of full grid lines.** You get the alignment of a grid with about as much ink on the page as a dot grid.

Nanami also sells a Japanese-market Crossfield, made by its partner in Japan and sold at Tokyu Hands and Loft. It has 384 pages, a 7 mm full grid and an orange or teal blue cover.

## How does Tomoe River paper behave?

**It resists feathering and bleed-through, but at 52 gsm it is see-through and slow to dry.** Nanami describes it as almost like dictionary paper, smooth but not slick, and "very quiet" under a fountain pen.

Nanami warns that firm writers can press impressions several pages deep, and suggests a writing mat. It includes a blotter sheet for wet inks, and recommends softer 2B or 3B pencil leads.

Since 2022, Tomoe River has been made by Sanzen Paper rather than Tomoegawa; see our [Tomoe River paper](https://stationerytimes.com/guides/tomoe-river-paper/) guide. The Well-Appointed Desk compared a 2017 Crossfield (2nd edition) with a 7th edition in 2025 and saw little difference in everyday writing. One commenter there felt the new paper was thinner and had less resistance.


## How does the Crossfield compare with other thin-paper notebooks?

**It has the most pages of the thin-paper A5 books we cover, and the plainest design.**

## Which Seven Seas journal should you choose?

**Choose the Crossfield for a quiet grid, the Writer for 7 mm lines, and the Standard for blank pages.** Nanami also lists a MicroDot grid journal and offers vinyl and leather covers sized for A5.

The flexible cover isn't stiff enough to write on in your lap, so many owners keep it in a cover. Nanami's own tip is to bend the book back on itself a bit so it lays flatter.

## How much does the Crossfield cost, and where can you buy it?

**It's in our $$$ band ($20–75 per notebook), sold mainly through Nanami's own US web store.** A shipping notice on Nanami's site dated October 4, 2020 says it ships to the United States only, citing long international transit times.

For 480 pages, that works out to a low cost per page compared with most premium A5 notebooks.

## Where is the Nanami Crossfield made?

**In Japan: Nanami's product page lists "Made in Japan", and its fact page says a third-generation binding factory in Tokyo makes the Seven Seas journals.** Nanami Paper itself is a small company in California, so the brand is American while the book, its paper and, Nanami says, its buckram cover come from Japan.

## Frequently asked questions

### How many pages does the Nanami Crossfield have?

480 pages, or 240 leaves, according to Nanami Paper. The Japanese-market Crossfield has 384 pages.

### What paper is in the Seven Seas Crossfield?

52 gsm white Tomoe River paper, which Nanami describes as off-white. The 8th edition uses the Sanzen-made Tomoe River paper, made before July 2024.

### What is a cross grid?

Instead of full grid lines, Nanami prints small gray crosses, about 2 mm across, every 5 mm. It guides your writing like a dot grid but stays in the background.

### Is the Crossfield good for fountain pens?
