Choosing fountain pen paper & notebooks means deciding whether you want pages that guide prose or pages that organize it visually. The Nanami A6 prioritizes prose-oriented journaling, while the Tomoe River Notebook offers visible page structure. Their listed prices are also USD 15 apart, so the useful question is which format you will actually use.
Quick verdict
Choose the Nanami A6 for a journal-first format with a lower listed price and a flat-opening design. Choose the Tomoe River Notebook when fountain-pen use and a defined notebook construction matter more. Both use Tomoe River paper, so the choice turns mainly on page layout, construction, and spend.

Product notes
Nanami A6 Lined Tomoe River Writing Journal

Nanami A6 makes sense for a journal routine that benefits from a specific paper feel. Its Tomoe River paper has a smooth texture, and the Japanese language and beige color give it a particular presentation that may suit a reader who wants those details on the page. The limitation is equally concrete: that language and color may not match a preference for a different presentation. At USD 24.99, it occupies the lower end of this comparison. Choose Nanami when the paper feel and presentation fit your routine; move to another format when a more structured page is your priority.
Tomoe River 5mm-Squared Grid Notebook

The Tomoe River Notebook is the paper-feel choice when fountain-pen writing is central. Its paper is thin and velvety smooth, and its writing use includes fountain pens and ink pens. Those details give shoppers a concrete reason to favor it alongside its notebook format. The limitation is the listed cost: USD 39.99, or a USD 15 gap above the Nanami A6. That higher price is harder to justify if paper feel and fountain-pen use are not priorities. The paper-focused reason is strongest for a shopper who wants that texture to shape the writing experience, rather than treating the notebook as a generic writing pad.
Final choice by use case
For journal-first use, the Nanami A6 is the clearer call: its title combines "Lined Notebook" and "Writing Journal," and it lists 384 pages. For structured layouts, the Tomoe River Notebook is the more relevant match because its title specifies a 5mm-squared grid. If price is the deciding factor, choose Nanami A6; if paper feel and fountain-pen focus matter more, choose Tomoe River Notebook. In short, select the lined journal for prose and the squared notebook when visible alignment is part of the way you write.
