MINEBEA MITSUMI Inc. (MinebeaMitsumi) will begin selling in-house produced masks made in the clean room of its Hamamatsu Plant (Fukuroi City, Shizuoka Prefecture). These masks will be available for purchase on Amazon.co.jp starting June 26.

On April 1, 2020, MinebeaMitsumi began producing masks in-house for its employees to wear, using the clean room of its Hamamatsu Plant, in an effort to deter the spread of the new coronavirus (COVID-19) outside of the company and to ensure the safety of its employees, as well as to fulfill its supply responsibility as a parts manufacturer through its production, sales, and general business activities.
The company has now decided to begin selling these masks externally in order to be of service to the people who need them amidst Japan's mask supply shortage.

MinebeaMitsumi would like to express its deep respect for everyone continuing to fight the spread of the new coronavirus (COVID-19) on the front lines, and will continue to provide necessary support against the spread of infection going forward.
