Why was Tokyo's Imperial Palace never bombed? Why weren't any of the governors' palaces of all the prefectures bombed either?

I also wonder what would've happened if the palaces had indeed been bombed? I also wonder why they'd bomb the factories and NOT the power plants. Why not the power plants first, then the factories? No power plants = slower to rebuild & recover.
