From a news report on Phys.org, April 20, 2015:
The Japan Aerospace Exploration Agency (JAXA) has unveiled the plan for a Moon lander. If successful, Japan will be the fourth country to send an unmanned probe to the moon after Russia, the United States, and China.
JAXA plans to launch the mission as early as 2018, with a development cost estimated at up to 15 billion yen ($126 million). The probe, named SLIM (Smart Lander for Investigating Moon), will be carried by the nation’s solid-fuel “Epsilon” rocket.
