Abstract
JAXA's clinical space medicine program seeks to improve the health, and well-being of Japanese astronauts. It plans to develop medical technologies to mitigate and manage medical risks around human space flight. To prevent bone loss and renal stone during space flight, prophylactic use of bisphosphonate for station astronaut has began this year through collaboration between JAXA and NASA. The process of JAXA's space medicine study, advisory committee for bone loss countermeasure program, and 90-day bed rest study were also shown in this article.
