Biological sabotage testing was also handled at this facility: everything from poisons to chemical crop destruction.
Senior Sgt. Kazuo Mitomo described some of Unit 100's human experiments:

On some of the prisoners I experimented 5-6 times, testing the action of Korean bindweed, bactal and castor oil seeds.

After the injection, the man died
