In the aftermath of the Apollo 11 moon landing, the United States invited western countries, including Japan, to participate in its "post-Apollo" space program, which consisted of two main elements, the "Space Shuttle" and the "Space Station." However, because the United States had decided to develop the Space Shuttle essentially on its own in 1972, Japan decided to participate in the Space Shuttle program in the field of utilization in 1974. This marked the begginning of Jpane's participation in internatinal space cooperation efforts and also led to Japanese human spaceflights after the 1990s. This article reexamines the relationship between Japan's space activities and the U. S. Space Schuttle program from the begining to the end, from the perspective of Japan=U. S. diplomatic history. It should be concluded that Japan's participation in the U. S. Space Shuttle program was a success in space policy becouse Japane became one of the advanced countries in space efforts by participating in the program and later in the International Space Station (ISS) program.
