[Post 1443] WW2 Germ Lab Cover-Up In Occupied Singapore: Oka 9420 | Inside Unit 731 - Extra

Summary

Singapore historian Lim Shao Bin uncovers the hidden story of OKA 9420 - a secret Japanese germ warfare base established in Singapore during World War II. Through rare archival material and testimony from the son of Dr JMJ Supramaniam, a young medical student recruited into the unit, the investigation reveals how plague-infected fleas were bred in Singapore and linked to biological attacks carried out by Unit 731 across China. Decades later, newly uncovered evidence and personal artifacts shed light on a forgotten chapter of Singapore’s wartime history.
