A pair of lost Japanese folding screens portraying the 1614 winter campaign of the Siege of Osaka have been brought back to life after painstaking work to reproduce them, including their original colours, using digital technology and an artisanal touch.

The restored artefact is a left-and-right pair of six-panel folding screens. The two painted sections are about 6 meters wide and about 1.7 meters high in total when they are placed side by side.

Under the supervision of experts, the project members restored the original colours with the help of digital technology. After an image was printed on paper, artisans manually placed gold leaf and silver leaf and other materials on it to give it a 3-D look. It took one and a half years to complete the work.
