The University Space Engineering Consortium (UNISEC) has been dedicated to facilitating and supporting practical space engineering activities at the university level in Japan since 2002. After 10 years of domestic activities, UNISEC has started to spread its university-level capacity-building activities to the rest of the world. This paper briefly describes UNISEC activities that would contribute to capacity building. UNISEC's international programmes which would be related to capacity building in the field of space science and technology are presented, followed by an examination on how they can improve the effectiveness of capacity building. Finally, future perspectives and its challenges on capacity building are discussed.
