Choosing fountain pen paper & notebooks comes down to a practical choice: do you want a dedicated journal format for writing by hand, or a larger paper supply for letters, planners, and everyday office use? Yu-sari and Kokuyo take different approaches. Yu-sari is a plain A5 notebook with quick-drying, ultra-smooth paper, while Kokuyo is a 500-sheet A4 paper pack designed for fountain pen and ink-pen use. The better pick depends more on format and quantity than on a simple paper-quality comparison.
Quick verdict
Choose Yu-sari if you want a fountain pen journal with a plain interior, Japanese notebook format, and eggshell-colored paper. Its listed price is USD 19.69. Choose Kokuyo if you need a larger supply for office writing, letters, or custom planners, with explicit claims of minimal feathering, no bleed-through during everyday writing, and double-sided use. It is listed at USD 27.69.

Product notes
Yu-sari Plain Fountain Pen Notebook
Yu-sari makes the more focused choice for someone shopping for a fountain pen journal rather than a general paper supply. The title identifies an A5 plain notebook, and the description adds an ultra-smooth texture, quick-drying properties, and eggshell-colored paper intended to make writing stand out. That combination gives the format a clear handwritten-journal role, and the USD 19.69 price keeps the purchase below Kokuyo's listed price. The limitation is equally concrete: the package is one plain notebook, not a 500-sheet paper ream. Shoppers who regularly write letters, prepare planner pages, or need repeated sheets may find the notebook format less suitable for those tasks.
Kokuyo Fountain Pen Paper
Kokuyo is the more practical fit when the priority is a substantial paper supply for fountain pen writing, office documents, or creative paper projects. The 500-sheet A4 pack, acid-free description, smooth surface, and stated minimal feathering give it a broader everyday role than a single journal. The description also specifically mentions performance across various nib types and ink saturations, plus double-sided use. Its limitation is the listed price: USD 27.69, or USD 8.00 above Yu-sari. Its print-copy-paper format also lacks the dedicated notebook presentation of Yu-sari, so it is better suited to loose-page work than to keeping entries in one journal.
Final choice by use case
- For a dedicated fountain pen journal: Pick Yu-sari, especially if a plain A5 notebook, quick-drying paper, and eggshell-colored pages match your writing routine.
- For office writing and repeated projects: Pick Kokuyo for its 500-sheet A4 supply and print-copy-paper format.
- For double-sided writing: Kokuyo is the clearer choice because its description explicitly states no bleed-through during everyday writing and suitability for two-sided use.
- For the lower listed price: Yu-sari is the choice at USD 19.69, compared with Kokuyo at USD 27.69.
In short, Yu-sari is the focused notebook purchase; Kokuyo is the larger paper-supply purchase. Decide whether your priority is keeping handwritten entries together or having sheets available for broader fountain pen work.
