The rovers are collectively known as MINERVA-II1.
The Japan Aerospace Exploration Agency's Minerva-II1 rover captured this view of asteroid Ryugu (bottom) and the Hayabusa2 spacecraft (at top right) just after the rover separated from the spacecraft on September 21, 2018.
"The two rovers are in good condition and are transmitting images and data", the space agency said.
Spectacular photos captured their "hop" onto Ryugu's barren surface. "This is just a real charm of deep space exploration", said Takashi Kubota, a spokesman for the space agency.
Taking advantage of the asteroid's low gravity, the rovers will jump around on the surface - soaring as high as 15 metres (49 feet) and staying in the air for as long as 15 minutes - to survey the asteroid's physical features. The Japanese unmanned spacecraft Hayabusa2 released two small Minerva-II-1 rovers on the asteroid Ryugu in a research effort that may provide clues to the origin of the solar system.
A series of specially designed cameras - four on the first rover and three on the second - will take stereo images of the asteroid's surface.
The suspense is over: Two tiny hopping robots have successfully landed on an asteroid called Ryugu - and they've even sent back some wild postcards from their new home.
In October, the Hayabusa2 probe will deploy an "impactor" that will explode above the asteroid, shooting a 2kg copper missile to blast a small crater into the surface.
The first-ever landing by a roving explorer on an asteroid means redemption for the Japan Aerospace Exploration Agency, which failed on a similar mission in 2005.
Hayabusa2 was launched in December 2014 and made its rendezvous with Ryugu in June this year.
The probe will also release a French-German landing vehicle named the mobile asteroid surface scout (MASCOT) for surface observation.
Japanese scientists are racing NASA for that achievement, with the USA agency's sample retrieval mission due to arrive back on Earth in 2023.
