Akio Tateya graduated from Agriculture Master course of Kyoto University and employed by the Ministry of Agriculture, Forestry and Fisheries (MAFF).

MAFF also agreed with me to be nominated as the member of Methyl Bromide Technical Options Committee (MBTOC) in 1993. I have participated the activity as a member of MBTOC since then.
