Masami Tsuchiya (土谷 正実, Tsuchiya Masami; 6 January 1965 – 6 July 2018) was a Japanese convicted terrorist and senior member of Aum Shinrikyo, responsible for the deaths of a combined 19 people and for the production of sarin, VX nerve agent, PCP, and LSD. He served in Aum's "Ministry of Health". Prosecutors described him as "the second most important figure involved in the gas attacks by the Aum Shinrikyo cult" after Aum leader Shoko Asahara himself.
