WRITING PAD A5 / SANZEN TOMOE RIVER S

Yamamoto Paper’s WRITING PAD series is a collection of writing pads that let you enjoy the textures and writing experiences of various types of paper. 

Sanzen Tomoe River S is characterized by its smooth writing surface and minimal ink bleeding when written with a fountain pen or oil-based ballpoint pen.

This paper does not wrinkle easily even when erased with a Frixion pen, making it suitable for use as a planner or memo paper.

The Tomoe River Paper Company discontinued their production of Tomoe River in 2021 due to a change in business direction.

However, in order to keep the worldly renowned Tomoe River alive, the brand was transferred to Sanzen Paper Mfg. of Kanazawa City, Ishikawa Prefecture.

Sanzen had been producing 52g/m2 pocketbook paper since 1976.

Using this experience, they reassessed the secret recipe that was a mixture of hardwood pulp (eucalyptus) and softwood pulp (pine, etc.) and reconstituted the quality of the paper as Sanzen Tomoe River S.

As a result, they were able to improve on the consistency of the pulp and create a paper that is smoother and more resistant to bleeding.

The paper is also 5 microns thicker, which gives it a firmer feel and greater strength against rubbing, which is useful for use with pencils and popular erasable pens.

Sanzen Paper Mfg. started full-scale production of Sanzen Tomoe River S in February 2022.

Fountain pen tests conducted by Yamamoto Paper showed that even with low viscosity inks such as J.

HERBIN’s pinks and reds, the drying time was quick and the ink did not bleed through even when large amounts of ink were put on the paper.
