    A new material that inherits the technology of Japanese paper from the desire of the Japanese paper maker Ohnao, located in Ichikawadaimon, Yamanashi Prefecture, which has a history of 1000 years, to "get more people to use Japanese paper products", thus we have developed "Naoron". Its features are the following three.

    Light! Soft!

    When your heard of the word "paper", it's easy to think that it will tear immediately, but the load capacity is 5 to 10 kg, so you don't have to worry about tearing even if you put heavy documents or materials in it.

    Supple while being durable as well

    It is resistant to water, dries faster than fabric products, and has the property of becoming stronger when it gets wet.

    Once wrinkled, it does not recover and becomes wrinkled

    On the contrary, the product brand "SIWA" was born in order to make the best use of its characteristics as "texture" and to enjoy using it like leather that "gain more grainy textures" as it is used.

    The origin of "SIWA" comes from the word "wrinkles" on paper (shiwa) and the opposite reading of "Japanese paper" (washi). Under the theme of "everyday use," we sell a variety of products under the theme of "genderless and ageless," such as bags and accessory cases that use "Naoron."

    Also pay attention to "sewing technology" where the seams are inconspicuous

    Designed by FUKASAWA Naoto. An award-winning industrial designer such as the "Isamu Noguchi Award". In addition, the material "Naoron" is excellent not only in functionality but also in sewing technology. The structure is such that the seams are inconspicuous because the craftsmen sew each stitch using a sewing machine.
