Sanzen Tomoe River Loose Leaf Paper – A4 is a refined expression of Japanese paper stationery, continuing the legacy of the beloved Tomoe River paper under new craftsmanship. Since 2021, Sanzen Paper in Kanazawa has faithfully carried forward the tradition, creating ultra-thin, fountain pen friendly sheets with more texture and durability than the original. While it remains silky smooth, it feels noticeably more resilient with a subtle tooth.
At 52 gsm, it balances featherweight thinness with surprising strength. Fountain pen ink glides effortlessly, delivering crisp lines with rich shading and sheen, while maintaining excellent resistance to feathering and bleed-through. Some users report that show-through (ghosting) is slightly reduced compared to the original, though still present depending on ink and pressure.
For those who prefer the earlier style, we also carry the Tomoegawa Tomoe River Loose Leaf Paper – A4
, made with the original stock produced before Tomoegawa ceased production. Together, these two versions allow fountain pen enthusiasts to experience both the classic and the new generation of Tomoe River paper.

Based in Sakai, Osaka, Yamamoto Paper was founded in 1972 as a paper specialist. Drawing on decades of experience connecting paper manufacturers with end users, they now design and produce their own original stationery. At the heart of their work is a belief in “sharing the joy and warmth of paper with confidence for generations to come.”
Rather than simply selling beautiful paper, Yamamoto Paper values delivering the full character of each sheet: its writing feel, texture, and the way it changes over time. They are also known as “custodians” of paper culture, reviving legendary papers that have gone out of production and passing them on to the next generation.
What makes Yamamoto Paper especially beloved is their balance of craftsmanship and playfulness. Their Paper Tasting series, for example, lets you sample different types of paper as if you were tasting wine, turning the exploration of paper into a delightful experience. It’s this combination of uncompromising quality and creative spirit that has earned them loyal fans among stationery lovers and fountain pen enthusiasts around the world.

"I love to write with a fountain pen and liquid ink from a bottle. This paper is excellent for that: lightweight, strong, smooth — the pen just glides across the surface, leaving a beautiful line of script."
