Decided to open a new thread, as the primary mission has been completed, and any news on the extended mission can be posted here.

"Japanese asteroid-sampling probe begins long trek to next space rock"

Hayabusa2's first extended-mission destination is the roughly 2,300-foot-wide (700 meters) asteroid (98943) 2001 CC21, which the probe will fly by at high speed in 2026, if all goes according to plan. A more in-depth rendezvous with yet another space rock, 1998 KY26, is scheduled to follow in 2031. (Hayabusa2 won't collect any samples from 2001 CC21 or 1998 KY26.)
