In Japan on September 23rd-25th is a national holiday time.
The Autumn Equinox is a national holiday and in parks all over Japan people will gather for moon viewing, an activity called “o-tsukimi.”
In the Heian period (794-1192), courtesans have written poetry under the moon, but nowadays most people stake out a patch of grass, spread out a cloth and eat sweets and drink tea or sake while watching the moon. Where I live, this is the only day of the year the botanical park is open at night and people are allowed to sit on the grass. A very special occasion indeed.
Wherever you happen to be in Japan at this time, there are surely going to be moon-viewing events or those celebrating the Autumn Equinox. Traditional Japanese events such as tea ceremonies, ikebana exhibits and Shakuhachi, or other live performances, abound. So grab a piece of grass, get some snacks and sake, and pray it doesn’t rain!
