New book reviews Japanese war crimes and US coverup

The book is a powerful documentary testament. Some of its revelations come in the form of rare historical photos that are being made public for the first time.

Jin, the author and curator of the museum, shared his journey of writing the book. During more than 30 years devoted to researching the history of germ warfare, preserving historical sites and disseminating information for education, Jin made dozens of trips to Japan, seeking evidence and interviewing former members of Unit 731.
