Kirishima Shrine

First, you wash your hands (and mouth, I think) here

Then go up to the altar and make a wish

You can also buy good luck charms (approx. 500 yen or up)

Or get your future predicted (the stall has four sides, and thus four types of predictions in the form of small rounded-up scrolls: those for kids, those of love, those for happiness, and those for general use).
