Unit 9420
From Wikipedia, the free encyclopedia
Unit 9420 or Oka Unit was formed in 1942 in Singapore by Naito Ryoichi.
The Unit had approximately 1000 personnel based out of the Raffles Medical University. The unit was commanded by Major General Kitagawa Masataka and supported the Japanese Southern Army.
There were two main sub-units, the Kono Unit which specialized in malaria and the Umeoka Unit which dealt with plague. In addition to disease experimentation, this facility served as one of the main rat catching and processing centers. Evidence points towards this facility also supplying a medical sub-unit operating in neutral Thailand with diseases for unknown operations and/or experiments. [1]
