Choosing between fountain pen paper & notebooks often comes down to two needs: do you want an A5, plain page for open-ended writing, or an A6, lined journal with 384 pages and a flat-opening design? The Yu-sari and NWT notebooks make that choice clear. Both emphasize smooth paper, but their formats, layouts, and named paper features suit different writing routines.
Quick verdict
Choose the Yu-sari A5 Plain Fountain Pen Paper Writing Pad Journal if an unruled layout, A5 format, and quick-drying paper are the priorities. Its listed price is USD 19.69, and its paper is described for fountain pen or rollerball ink with an ultra-smooth texture.
Choose the NWT A6 Lined Notebook 384 Pages Tomoe River Nanami Paper Writing Journal if ruled pages, Tomoe River paper, and a 180-degree opening matter more. It costs USD 24.99, making the price spread between the two notebooks $5.30.

Where Yu-sari has the edge
Yu-sari is the stronger fit for flexible page planning because its interior is plain and its format is A5. The fountain-pen-focused paper description also gives it a specific role for handwriting with fountain pen or rollerball ink, while quick-drying properties may appeal to writers who want that characteristic named up front. At $5.30 below the NWT, it also keeps the entry price lower. The trade-off is that plain pages do not provide the ruled guidance found in the NWT notebook, so the layout choice is important rather than incidental.
Where NWT has the edge
NWT is the more direct match for a lined journal routine. Its 384-page count, Tomoe River paper, and 180-degree opening are concrete reasons to choose it when page structure and a flat workspace are central to the purchase. The A6 format and beige color give the notebook a distinct physical profile, while Japanese language is also identified. The limitation is equally clear: its A6 lined layout is not the direct match for someone seeking the A5 plain format used by Yu-sari.
Product notes
Yu-sari A5 Plain Fountain Pen Paper Notebook

Yu-sari suits writers who want an unruled page and the A5 format named in its title. Its paper is presented for fountain pen or rollerball ink, with an ultra-smooth texture and quick-drying properties. The description also identifies thick paper, giving the notebook a defined paper-focused profile for handwriting and general writing. That combination makes it the sensible pick for flexible layouts, freeform notes, or users who do not want printed ruling to dictate spacing. The concrete limitation is the plain interior: anyone who prefers lined journaling will need to supply their own guides or choose the NWT format instead. Yu-sari is therefore the better fit when blank-page control matters more than a preset journal structure.
NWT A6 Lined Tomoe River Nanami Notebook

The NWT A6 Lined Tomoe River Nanami Notebook is built around a more guided writing format. It combines lined pages with 384 pages and Tomoe River paper, while its design opens flat at 180 degrees. Those details make it a natural choice for a journaler who wants consistent ruled writing space and a notebook that can lie open during use. Its beige color and Japanese language are also specifically identified. The limitation is its A6 lined format, which makes it less suitable for someone whose deciding requirement is the A5 plain layout of Yu-sari. Pick NWT when the page count, ruling, and flat-opening design matter more than blank-page flexibility.
Final choice by use case
- For plain-page writing: Choose Yu-sari, because its A5 interior is plain and its paper is described as ultra-smooth and quick drying.
- For lined journaling: Choose NWT, whose A6 format is lined and specified at 384 pages.
- For a notebook that opens flat: Choose NWT, with its stated 180-degree opening.
- For fountain pen or rollerball use with quick-drying properties called out: Choose Yu-sari.
- For Tomoe River paper specifically: Choose NWT, since that paper is named directly in the product.
The decision is ultimately layout-led: Yu-sari favors an A5 plain-page setup, while NWT favors an A6 lined journal with a stated page count and flat-opening construction.
