Tosa paper is a traditional Japanese paper known for its strength and durability. Originating from the Kochi Prefecture on the island of Shikoku, it is made using the bark of the kozo plant, which is a type of mulberry. The production process involves handcrafting techniques that have been passed down through generations, resulting in a unique texture and appearance. This paper is often used for various applications, including calligraphy, painting, and crafts. Its ability to absorb ink well makes it a favorite among artists and writers. Additionally, Tosa paper is appreciated for its eco-friendly qualities, as it is made from natural materials.
