Hobonichi Techo / ほぼ日手帳
A familiar reference for compact, high-page-count planners. Ask which exact edition and year is being compared; avoid treating every notebook sold under a brand as one permanent paper specification.
JAPANESE PLANNER & NOTEBOOK PAPER
Searching for the paper behind a favourite Japanese notebook is a useful starting point. A brand name alone, however, is not a purchasable raw-paper specification. This independent guide separates finished stationery brands, named paper grades and the requirements of B2B notebook production.

JAPANESE PLANNER & NOTEBOOK PAPER
A familiar reference for compact, high-page-count planners. Ask which exact edition and year is being compared; avoid treating every notebook sold under a brand as one permanent paper specification.
KOKUYO identifies its own THIN PAPER and MIO PAPER across different Jibun Techo products. These are branded paper specifications, not interchangeable generic grades.
Official refill information lists multiple papers and identifies MD Paper in certain notebook refills. Always compare the exact refill number, not simply the cover brand.
MD PAPER is a distinct paper identity associated with writing-focused stationery. Assess colour, writing response and desired finished format; do not assume its raw sheets are available through FUKUSEI.
Brand names are used for independent technical comparison only. FUKUSEI does not claim affiliation with these stationery brands, authorization to sell their proprietary paper, or exclusive distribution rights.
Discuss Tomoe River S 52 gsm or 68 gsm and test show-through, binding, page weight and pen performance. Confirm the exact current grade and supply conditions.
Compare iroful 75 gsm with the intended pens and inks. Its consumer specification does not automatically establish parent-sheet availability.
Evaluate b7 Natural for paper tone, printing, bulk, writing and binding. It is classified as a printing paper; a writing test remains essential.
Consider Marshmallow CoC, View Corona or other grades based on printing method, grammage, size and finishing rather than a similar-sounding finished-product brand.
Send the intended planner or notebook format, page count, reference brand or sample, target gsm and colour, pen/ink requirements, parent-sheet size, first lot, annual demand, FSC requirements if any, and shipping destination.

No. These are separate named paper identities. Even where writing performance goals overlap, do not substitute one for another without sample, specification and supply checks.
FUKUSEI can review Japanese-origin base-paper enquiries with the desired finished format, gsm, colour, paper dimensions, initial and annual quantity, writing tests and destination. Current availability and terms are confirmed for each project.
