Isshoni Number Notebook – [A6, A5]

A notebook that actually helps you locate your own thoughts later — what a refreshingly modern courtesy. The Daigo Isshoni Number Notebook takes the brand’s signature numbered pages and index system and offers them in two practical formats: a portable A6 square and a spacious A5 plain.

The A6 size slips neatly into bags and pockets, and even accommodates the standard pharmacy dispensing sticker, making it surprisingly handy as a medication notebook. The A5 plain version, meanwhile, gives you an open canvas for sketching ideas, keeping a picture diary, or building a recipe collection without ever feeling confined by lines or grids.

You simply note the page number on the index, write wherever inspiration appears, and later return to that thought instantly — no aimless flipping or “surely it must be near the back” moments. With diagonal page numbers for horizontal or vertical use and a scratch-resistant polypropylene cover you can wipe clean, this is a notebook built for daily thinking without unnecessary fuss.
