This concept seems so far fetched to me - not the idea of a moonbase itself, but planning one over twenty years in advance:
"It takes something fairly outlandish to raise eyebrows in today's scientific and technological communities, but the Japan Aeorspace Exploration Agency (JAXA) did just that at an international conference held in Tokyo last week. The agency announced its goal to build an inhabitable base on the moon by 2030. Preceding the construction of the lunar base, JAXA has some work to do. Junichiro Kawaguchi, the Japanese agency's director, said the current plan is to send astronauts to the moon in 2020 to begin construction. In the immediate future, the Japanese space program plans to send a new satellite into orbit and unmanned, robot-run missions to the moon to collect rock samples from the moon's surface as early as next year."
