The Hyper Suprime-Cam is a huge camera installed on the 8.2m Subaru telescope. We are conducting a 1400 sq deg imaging survey in grizy bands to unprecedented depths. I will show some early science results from this survey as well as discuss ongoing weak lensing related science. I will also describe a novel microlensing experiment we have conducted using this instrument which allows us to put the world's best limits on lunar mass scale primordial black holes. This closes the window on the primordial black
hole scenario for the nature of dark matter. I will further describe our ongoing search for the predicted Planet Nine, as well as the hunt for the  edges of the Milky Way using the Hyper Suprime Cam instrument.
