Choosing fountain pen paper & notebooks is a deceptively specific decision: two A5 choices can point to very different writing routines. One is built around a named paper identity and fountain-pen use; the other puts a plain page and Japanese notebook format at the center. The useful question is not which name sounds more appealing, but whether you care most about paper handling, page freedom, or the price gap.
Quick verdict
The A5 Notebook is the paper-focused pick, especially if its refill-oriented design suits your journal system. Yu-sari is the more format-led choice for shoppers drawn to its Japanese notebook presentation. The final call turns on whether the named paper specification or the notebook format matters more.
Price and format at a glance

Where each product wins
- A5 Notebook - 68gsm Tomoe River Paper: This is the better match when a specific binding cue and white presentation are part of your notebook preference. Its construction is identified as thread bound.
- Yu-sari Notebook A5 Plain: This option fits shoppers who want the A5 format and the Japanese wording included in its product name. It presents a more defined notebook identity for a straightforward writing setup.
Product notes
A5 Notebook - 68gsm Tomoe River Paper

A concrete reason to choose the A5 Notebook is its explicit paper identity: 68gsm Tomoe River paper and fountain-pen-friendly use are named together. Its smooth paper is also described as resisting bleed-through and feathering, while the acid-free wording gives it a preservation-oriented cue for notes and sketches. That makes it a natural match for shoppers searching specifically for Tomoe River paper or writing paper for fountain pens. The main limitation is the refill framing. It is designed for the Field Journal and Field Folio A5, so shoppers seeking a journal selected primarily as a self-contained book rather than around a refill system may find Yu-sari's format more natural.
Yu-sari Notebook

Yu-sari's main reason to choose is its paper experience for fountain pen or rollerball ink: it pairs an ultra-smooth texture with quick-drying properties. The paper is also described as thick, giving this notebook a distinct paper profile without requiring a particular page layout. That suits shoppers who want an open writing surface and a Japanese notebook identity. The clearest limitation is its plain format: people who prefer ruled or grid guidance may find an unstructured page less suitable. This is a deliberate trade-off for freeform writing. The A5 sizing keeps the use case straightforward, while the deciding attraction is the combination of smooth texture and quick-drying properties.
Final choice by use case
- Choose the A5 Notebook when 68gsm Tomoe River paper, fountain-pen-friendly wording, and resistance to bleed-through and feathering are the deciding details.
- Choose Yu-sari Notebook A5 Plain when ultra-smooth texture and quick-drying properties for fountain pen or rollerball ink matter more.
- Choose the A5 Notebook for price: its USD 16.56 listing is the lower-priced entry in this comparison. Choose Yu-sari if its paper description is worth the additional $3.13.
The bottom line is simple: the A5 Notebook is the paper-led choice, while Yu-sari is the choice for shoppers prioritizing its described writing feel and Japanese A5 format.
