It carries a number of sensors to investigate the environment of space, and its own status. It also contains a voice transmitter, intended to play back messages to amateur radio operators.{{cite web|url=http://cubesat.aero.cst.nihon-u.ac.jp/english/Pressrelease/SEEDS2_launch_report_eng.pdf|title=Report of the launch of SEEDS II|date=28 April 2008|publisher=Nihon University|access-date=19 October 2008|url-status=dead|archive-url=https://web.archive.org/web/20081203080645/http://cubesat.aero.cst.nihon-u.ac.jp/english/Pressrelease/SEEDS2_launch_report_eng.pdf|archive-date=3 December 2008|df=dmy-all}}
