Abstract
Japan has a formidable tradition in immunological research, starting with Shibasaburo Kitasato (1852–1931), who, after returning to Japan from his studies with Robert Koch, went on to build almost single-handedly a research tradition in investigative medical research, while engaging himself in the fight against infectious diseases1. Over the past few decades, Japanese immunologists have been involved in many important discoveries at the forefront of immunological research, yet, when it comes to the translation of new discoveries into clinical innovations and new therapies, Japan's track record seems more modest.
