Uchiyama was one of the biggest Shoji paper production areas 100 years ago. Today, only Abe family keeps making hand-made Shoji paper in this district.
The Washi making technique was imported from Mino in AD1661, and they have kept improving the paper as the snow country paper maker for the white paper. This place is located in a heavy snow area, there was a part of the Winter Olympic game in 1998.
The genuine Shoji paper is sold as the rolled form. Therefore, the genuine Shoji door should become masonry with the seam like the photo#2.
