The far shore is a Buddhist event, held twice a year around the spring and autumnal equinoxes, during which time memorial services are held for ancestors. The spring and autumnal equinoxes are called the “middle days of the equinoxes” respectively, and the period of the equinoxes lasts three days before and after each other, for a total of seven days. During this period, people visit graves and make offerings to express their gratitude to their ancestors. Purifying the graves and Buddhist altars is sometimes called omigaki (polishing). Here is a free illustration of a man preparing for the far shore to express his gratitude to the deceased.
