Yamamotos Writing Pad contains the paper Sanzen Tomoe River S, a further development of the original Tomoe River.
Sanzen is the name of the new manufacturer, who bought the rights after the previous owner stopped the production in 2021 due to a change in business direction. Sanzen has been producing 52g/m2 paper since 1976, and using this experience, they re-evaluated the secret recipe which was a mixture of hardwood pulp (eucalyptus) and softwood pulp (pine, etc.) and reconstructed the quality of the paper for the new Sanzen Tomoe River S.
The new paper is 5 microns thicker, and therefore gives a slightly firmer feeling, which means it can now handle erasers. The drying time for fountain pens is also slightly shortened. The pad comes with a gridded underlay.
