Every year, on the equinoctial week in spring and autumn, many people go to visit ancestors' graves and visit temples. In Japan, it seems to be a custom that began among nobles during the Heian period. Although Buddhist events have become commonplace, it is a unique event in Japan that is not found in other countries related to Buddhism, such as China and the Korean Peninsula, as well as India, the birthplace of the first place. In the latter half of the Edo period, even among ordinary people, the equinoctial week began to be incorporated into daily events.

There are various theories about why such customs have taken root in Japan, but I guess it was naturally established in the Japanese climate. In other words, on a special day when the length of day and night were aligned and the sun climbed and descended from the east, I think he naturally had awe and appreciation. At the same time, in this country, which is rich in the colors of the four seasons, I think it was time to feel the sense of the season, as symbolized by the saying "Heat and cold to the equinoctial week."
