Bus timetable here -

Assuming on time arrival, you should comfortably make it onto the 10.30 bus, which has an ETA of 11.40. Plenty of time for a domestic departure - even if there is some congestion. I would not worry about it.

For future reference - If you are looking for alternatives, you might also look for flights from UKB to HND. (UKB can be reached via ferry from KIX).
