Yamamoto Writing Pad A5 / Sanzen Tomoe River S

The WRITING PAD A5 featuring Sanzen Tomoe River S paper offers an exceptional writing experience for fountain‑pen users and paper enthusiasts. Following the discontinuation of the original Tomoe River paper in 2021, Sanzen Paper re‑engineered the formula using advanced papermaking expertise to preserve and refine its renowned qualities.

This 52 g/m² paper features improved surface smoothness, more uniform fibre bonding, increased stiffness, and enhanced resistance to ink bleed‑through and wrinkling—even when erased with friction pens. It performs beautifully with low‑viscosity inks, delivering fast drying times and clean results on both sides of the page.

Part of the Yamamoto Paper Industry WRITING PAD series, this pad is designed to preserve and celebrate distinctive writing papers that may soon disappear due to industry consolidation. Each pad lets you experience the unique character of carefully selected Japanese papers in a practical, everyday format.
