Seven microsatellites were deployed as piggyback payloads to the Ibuki spacecraft. All of these spacecraft will follow a similar roughly 660 km sun-synchronous orbit. Six of the small satellites were developed by universities and private-sector companies; the seventh is a technology demonstrator for JAXA.

KKS 1, developed by Tokyo Metropolitan College of Industrial Technology, is a cube of approximately 15 cm and 3 kg mass. The goal of this educational satellite is to demonstrate a micro propulsion system and three-axis attitude control functions.
