Japan’s most loved papers
PAPER WE CHOSE
For Notebook Light, Rehiie selected Tomoe River by Sanzen and Cosmo Air Light—two papers trusted by writers for how clearly and honestly they reveal ink.
Tomoe River is ultra-thin, smooth, and expressive: strong shading, bright sheen, and gentle ghosting with almost no bleed.
Cosmo Air Light is thicker and more opaque, with vivid color, rich gradients, and a soft cushioned feel under the nib.
We chose these papers because they embody what Rehiie values—
clarity, softness, and a quiet respect for the act of writing.
Two papers, two writing moods:
one airy, one steady.
