This book provides a comprehensive account of Japan's space program, including the history of its space organizations, laws, and policies. The two main laws covering space activities are the Act on Launching of Spacecraft, etc. and Control of Spacecraft, and the Act on Ensuring Appropriate Handling of Satellite Remote Sensing Data, both of which are discussed in detail. Also closely examined is the 2020 Basic Plan on Space Policy, which deals with the broad policy goals and specific programs of Japan's space development. In addition, a more general overview of Japanese foreign investment legislation is discussed for the benefit of non-Japanese participants in Japan-based space activities.
