Made in Japan, this simple notebook was designed to create a writing experience that you will enjoy. The high-quality Midori Diary (MD) paper inside was developed in 1960 and has been continuously improved on ever since. Midori has conducted many tests using a variety of writing instruments to inspect the paper quality, including observing whether the ink feathers or bleeds, how it dries, how well the pen tips glide across the surface, how the paper feels to the touch, and so on. As a result, the paper is bleed-resistant, feather-resistant, and fountain-pen friendly, giving the user a pleasant writing experience. The line ruling on the paper features a bold center line that divides each page into a top and bottom section, helping you organize.

The notebook has a sturdy thread binding that lies flat when open, making it easy to write. The cover is not a typical notebook cover. To feature the charm of the paper itself, the cloth tape used to bind the spine, usually hidden by a cover, is exposed, giving the notebook a unique look.
