October 22 and 23
Hi Matsur is a Japanese festival of purification and is celebrated annually at this time. Beginning on the eve of the 22nd there are torchlight processions and parades through the streets in honor of the ancient Gods. The procession ends at a sacred shrine in Kurama, where it is believed that the ancient ones return to Earth at the stroke of midnight. Prayers and invocations will be offered the following day.
