SAKAE TP Tomoe River FP Loose Sheets A4 Plain White 52 gsm 100 Sheets

SAKAE TP Tomoe River FP Loose Sheets A4 Plain White 52 gsm 100 Sheets

The SAKAE TP Tomoe River FP Loose Sheets A4 Plain White 52 gsm 100 Sheets provide the freedom to use Japanese fountain pen paper without a fixed binding. Each lightweight sheet offers a generous surface for letters, calligraphy, ink records, drawing and personal projects. An ideal choice for writers who want to organise, fold or store every sheet independently.

Independent sheets for flexible projects

The pack contains 100 completely unruled A4 sheets with no lines, dots or grid. Because the paper is neither glued nor bound, each sheet can be used separately, filed, folded or cut to suit a particular project. The 210 × 297 mm format provides ample room for long-form writing, correspondence, handwriting practice, sketches and detailed ink records.

At Inktraveler, we find this format particularly useful for comparing inks and nibs on a consistent surface or for building a personal writing system that is not limited by the structure of a notebook.

52 gsm Tomoe River FP paper by Sanzen

The white Tomoe River FP paper is produced by Sanzen and weighs 52 gsm. FP stands for Fountain Pen, reflecting the intended use of this writing-paper range. Its smooth surface supports clean lines and helps display ink colour, shading and sheen. Exact results will naturally vary with the ink, nib width and flow selected.

Its low weight keeps a full pack of 100 sheets remarkably light and compact. Some writing may remain visible from the reverse because the paper is exceptionally thin. This show-through is a normal characteristic and should not automatically be mistaken for bleed-through, against which Tomoe River FP is designed to perform carefully.

A4 space for writing, calligraphy and ink exploration

The plain surface places no restrictions on page layout. It can be used for handwritten letters, calligraphy exercises, illustration, colour studies, fountain pen testing or individual records that need to be stored separately. The white paper creates a neutral background that presents ink colours clearly and gives finished work a clean appearance.

Unlike a paper pad, these sheets are supplied loose inside the package and are not attached with adhesive. Users can remove only the quantity they need, rearrange their work, exchange ink samples or place finished sheets in their preferred folder and filing system.

Contents and presentation

The package contains 100 independent A4 sheets of plain white 52 gsm Tomoe River FP paper. SAKAE TP updated the exterior packaging in 2024 without changing the product reference, EAN or contents. The pack received may therefore differ from earlier photographs. (Photographs are for reference; paper tone and minor visual details may vary slightly according to the display or production batch.)

Brand history and philosophy

SAKAE Technical Paper is a Japanese company specialising in writing papers and thoughtfully developed stationery. Tomoe River earned an international following among fountain pen users by combining exceptionally low paper weight with a surface that reveals ink characteristics without making notebooks and paper archives unnecessarily bulky.

In January 2023, SAKAE TP introduced its renewed Tomoe River FP range using 52 gsm paper produced by Sanzen. It returned in A4 and A5 formats and in white and cream paper colours. The loose-sheet presentation follows a straightforward principle: provide the paper without imposing a binding, allowing each writer to decide how it should be used, organised or transformed.

Frequently asked questions

Are these sheets suitable for fountain pens? Yes. Tomoe River FP is intended for fountain pen writing and helps reveal a wide range of ink characteristics. Performance will still depend on the selected ink, nib width and flow.

How do loose sheets differ from a paper pad? Every sheet in this product is separate and unglued. Sheets in a paper pad remain attached along one edge until they are removed.

Is the paper white or cream? This reference contains white paper. SAKAE TP also offers separate cream-paper references, so checking the product code is useful when choosing between them.

Does visible show-through mean that the ink has bled? Not necessarily. With 52 gsm paper, writing may be visible from the reverse side without the ink actually passing through the sheet.

Can both sides be used? Both sides can be used with many fountain pen and ink combinations. Readability will depend on ink application and the user’s personal tolerance for show-through.
