Here’s another Japanese shop that makes customized notebooks to order:

Kakimori is the brainchild of owner Hirose Takuma, who opened the shop in 2010 as a place for writing fanatics. He stocks the store’s shelves with an impressive lineup of fountain pens and other items carefully chosen from leading Japanese and overseas stationery brands, winning him accolades for his taste in products. But it is Kakimori’s customized notebooks that have turned the Kuramae store into a popular stop-off for Japan’s profuse population of stationery lovers.

To create a notebook, customers choose from 60 cover types, including solid hues and decorative designs, and 30 varieties of paper. To add a personal touch and bind everything together, Kakimori provides a broad range of rings, ribbons, and fasteners in attractive colors. After selecting the various parts, customers hand everything over to staff who bind the notebooks in around 20 minutes.
