Sachie currently resides in Chiba, Japan. She graduated from the graphic design department at Kuwasawa Design School. She first worked at a design office and then started learning Kaga-Yuzen dyeing :​ a traditional Japanese dyeing technique for kimonos that originated in Kanazawa, Ishikawa prefecture.

​She started to create lamps, and after much trial and error she finally reached her ideal washi (Japanese Paper) lamps. She held her first personal exhibition in 2003, and since 2013 she began selling at higt-end department stores and various shops all over Japan. Sachie Muramatsu's lamps are getting more and more media exposure and orders come from not only from Japanese customers but also from oversea customers.
