The first result in Japanese planetary geodesy was brought by the asteroid mission Hayabusa which estimated the bulk density of the asteroid Itokawa through the measurements of gravity and shape. The Japanese lunar mission SELENE was also successful in terms of geodetic research to achieve developing improved models of the lunar topography and gravity. I review the international circumstance around the time of SELENE, the framework of SELENE geodetic mission operation, and the scientific outcomes from SELENE geodetic mission instruments. I point out the current difficulties in promoting future missions and propose possible approach to solve the problems.
