Other reports are more definite...no landing.

"After analyzing the data returned by the spacecraft, however, the team
found that Hayabusa continued its slow descent following the target
marker until it got to within about 10 meters (32.8 feet) of the big
rock, and then it autonomously went into safe mode, according to a
report issued by the Hayabusa Joint Science Team members that the
mission's Project Manager, Jun'ichiro Kawaguchi, sent to The
Planetary Society yesterday afternoon. Instead of landing, the
spacecraft apparently cruised above the surface for awhile, until
mission control signaled to the spacecraft to abort the landing
altogether."
