[Colleagues Association: A medical organization in modern Japan]

Colleagues Association was established in Tokyo, Japan in June, 1902 as a professional medical group aiming at the spread of advanced Japanese medical science in China and to other neighboring countries. Until February 1946, it carried out many medical activities such as opening hospitals and publishing journals for over four decades. It flaunted the banner of medical spread and exchange, but on the other hand, it provided Japanese army with medical service and facilities and resisted European and American medical activities after being supervised by the Japanese government with the aggression against China. So it changed into a medical organization to assist the Japanese government to invade Asia.
