A Japanese notebook born from the quiet brilliance of Japanese papermaking. At Komorebi Stationery, we believe that a truly good notebook does more than record—it inspires. That is why we were deeply moved by Yamamoto Paper’s Canopus, a paper created through years of research, testing, and an unwavering devotion to the art of writing. When the legendary Cosmo Air Light was discontinued, fountain pen lovers around the world were left searching for its successor. Refusing to compromise, Yamamoto Paper spent three years developing a new paper worthy of that legacy. The result was Canopus—a soft, micro-coated, high-bulk paper designed to express every nuance of ink shading and the shimmering beauty of color inks. Named after Canopus, the second-brightest star in the night sky and a symbol of peace and longevity in Japan, this paper reflects the same spirit: a light that continues to shine quietly, even through change. With its 73 gsm weight, Canopus offers the luxurious thickness of 150 gsm coated stock while remaining surprisingly light. Each page welcomes your favorite fountain pen, delivering smooth ink flow without feathering or bleed-through. The tactile softness invites you to slow down, listen to the sound of your pen, and enjoy every moment of writing. The notebook’s section-sewn binding allows it to open flat to 180 degrees or fold completely back, ensuring long-lasting durability even with daily use. Subtly rounded corners prevent damage, and a guide sheet (6 mm grid / 12 mm lined) is included to support both structure and creative freedom. We selected this notebook not simply for its specifications, but for its soul—the way it transforms ink into emotion. Whether you journal, sketch, or plan, the Canopus Notebook will remind you why writing by hand still matters.
