Satellites of Japan (Nippon), State of

221 satellites in orbit, 121 operating.

The count is the catalogue’s as of Nov 8, 2026, 4:17 PM; whether a satellite is operating is as Orbinauts writes it where it has written when the satellite’s mission ended, and otherwise as Jonathan McDowell’s general catalogue believes it, licensed CC BY 4.0: GCAT

GCAT, Jonathan McDowell’s general catalogue (CC BY 4.0), credits these satellites to Japan (Nippon), State of under the code J.
