Japan Blue Project
Japan Blue and its origin
The ancient technique of “Aizome”, or “Jazapanese Indigo dyeing” was first introduced to the country in the Asuka period (710-794). It grew in popularity until its beauty became recognized throughout the country in the Edo period. “Ai-iro” (translated to “blue color”), the basis for all other blues of Japan, which has also become the country’s iconic color, continues to hold a special meaning in the hearts of the Japanese people.
True to our Japanese heritage, PLOTTER proudly introduces indigo blue as a quintessential and representative color of Japan to the United States through our Japan Blue Project.

Japan Blue Project
Japan Blue Project is the first US Exclusive project by PLOTTER. It includes a line-up of PLOTTER 6-Ring Leather Binders with US Exclusive Shiranami Leather in A5, Bible, and Mini Size, as well as its complementary special Refill Memo Pad made with high-quality blue color paper in “Quadrant Graph”.
Shiranami – White-crested waves
Shiranami leather is a new leather type developed by PLOTTER in conjunction with a historic tannery in Himeji, an area known for its expertise in leather. Not only is it dyed with natural indigo but is also inspired by “Thirty-Six Views of Mount Fuji” by Japanese ukiyo-e artist Hokusai. The signature piece “The Great Waves off Kanagawa” depicts the turbulent, white-crested waves that dominate the scene, whilst Mt. Fuji poses quietly in the background. In Japanese, these crashing waves are called “shiranami.”
Blue Paper – 4 Quadrant Graph
The Refill Memo Pad Blue version is made with high-quality blue color paper. The layout is based on PLOTTER’s iconic 2mm Grid, with easy-to-read solid gray guidelines in a 4-division quadrant layout that lends itself to a variety of creative uses. The flexibility of the Refill Memo Pad allows you to use it comfortably as a notepad, while you can freely tear off only what you need for your leather ring binder.
