I was unable to find any information about this Japanese art or recycling old kimonos into silk paintings. The technique, from what I understand involves creating a painting, and transferring the sketch on a wooden panel. After that, selecting the colors of silk pieces, and cutting slivers of it to fill in the image.
The wooden panel then gets thin slits alongside the various details of the picture. the slivers of silk, then, are carefully wedged in those slits, "coloring" the panting". Sounds pretty lengthy work, but the result is amazing. The painting takes on a very unusual texture and clarity of detail. Precise and delicately beautiful, much like Japan itself.
