made in China. There is no indication of JIS. Blue plastic case comes with it. The color of the supporting part of the micrometer was different from the photograph, it was a silver painting, not a silver paint. There is no mark of Niigata Seiki in the case, and it is written only as "OUTSIDE MICROMETER 0 - 25 MM 0.01 mm" with an orange seal. Is it an OEM from a Chinese manufacturer? The adjustment of the zero point was hard and hard. The first rotation was not smooth, but it turned out to be good if I spun it for a while.
