The paper discusses the Japanese first lunar mission named "Hiten". The spacecraft system, its major mission objectives, namely, the double lunar swingby experiments and the insertion of a miniaturized sub-satellite into an orbit around the moon, are presented. The results of these engineering missions, and other experiments such as optical navigation, packet telemetry by use of a fault tolerant computer and detection of micro-meteorite particles in space of the Earth-moon system, are also described. A couple of follow-on missions, which may be conducted if the Hiten spacecraft will survive the aerobraking experiments at the end of its original 1 year mission life, are discussed. These follow-on missions include an excursion to the Lagrange points of the Earth-moon system and orbiting the Hiten spacecraft itself around the moon.
