SAKAE TP Tomoe River FP Loose Sheets A5 Plain White 52 gsm 100 Sheets
The SAKAE TP Tomoe River FP Loose Sheets A5 Plain White 52 gsm 100 Sheets provide a compact and flexible way to use Japanese Tomoe River paper without a binding. Designed for fountain pen writing, calligraphy, correspondence, ink testing and personal projects, every sheet can be used, filed or arranged independently.
A practical A5 format for individual projects
Each sheet follows the standard A5 dimensions of 148 × 210 mm. The size provides enough room for letters, handwriting practice, ink records, sketches and detailed notes while remaining easier to store and carry than A4 paper. The sheets are completely plain, with no lines, dots or grid influencing the layout of the page.
At Inktraveler, we find this loose A5 format particularly useful for building personal ink archives, preparing handwritten correspondence and creating custom inserts without committing an entire notebook to a single subject or project.
Tomoe River FP paper made by Sanzen
The white 52 gsm Tomoe River FP paper is manufactured by Sanzen in Japan. The FP designation reflects the range’s focus on fountain pen writing. Its smooth surface supports clean lines and allows many inks to display their colour variation, shading and sheen, although the final result will always depend on the ink, nib width and flow.
At 52 gsm, the paper keeps a pack of 100 sheets remarkably slim and lightweight. Some show-through may be visible on the reverse, particularly with dark inks or wet nibs. This is a natural consequence of the paper’s low weight and should not automatically be mistaken for bleed-through.
A white surface for accurate ink colour
The white paper creates a neutral background that helps ink colours appear clear and easy to compare. It is well suited to swatch collections, correspondence, calligraphy and other work where colour accuracy matters. The unruled surface also gives complete control over orientation, spacing and composition.
Loose sheets rather than a glued paper pad
All 100 sheets are separate inside the package. They are not bound or glued together, so there is no need to tear a sheet away before using it. The paper can be filed, folded, punched or trimmed to create custom inserts, small notebooks, writing sets and personalised organisation systems.
Pack contents and presentation
The package contains 100 individual A5 sheets of plain white Tomoe River FP paper at 52 gsm. SAKAE TP updated the exterior packaging while retaining the same product reference and JAN code, so the pack supplied may feature one of the brand’s original designs. (Photographs are for reference only; packaging, paper tone and minor visual details may vary slightly according to stock or screen settings.)

SAKAE TP history and paper philosophy
SAKAE Technical Paper was established in its current form in 2016, continuing a Japanese business tradition centred on planning, converting and supplying specialist paper and stationery products. Its paper-focused philosophy treats each sheet as a practical space for expression, discovery and the development of new ideas.
Production of Tomoe River paper was transferred to Sanzen in 2021. SAKAE TP renewed its Tomoe River FP stationery range around the Sanzen-made paper in 2023, preserving the qualities valued by fountain pen users while giving the product family a clear and consistent identity.
Frequently asked questions
Are the sheets glued together?
No. All 100 sheets are supplied loose and can be removed from the package individually.
Is this paper suitable for fountain pens?
Yes. Tomoe River FP is intended for fountain pen ink, although performance will vary according to the ink, nib and writing flow.
Does visible show-through mean the ink has bled through?
Not necessarily. The 52 gsm paper is very thin, so writing may remain visible through the reverse even when the ink has not penetrated the sheet.
How is this product different from a paper pad?
A paper pad keeps its sheets together with adhesive. These sheets are already separate, making them easier to file, sort and adapt to individual projects.
“A compact sheet can give an ink, a thought and a handwritten line exactly the space they need.”
