One of Japanese national holiday "Shunbun-no-hi" ( = the spring day),
which is known as Vernal Equinox Day.
The day time and the night time are equal in a day in Japan.
It's today, 21st March this year.
(It's changed by the year, 20th March for some years.)
"Higan", or more commonly "O-higan" is a day linked to Buddhism,
and refers to a week around "Shunbun-no-hi" (Vernal Equinox Day)
or "Shubun-no-hi" (Autumnal Equinox Day).
So "O-higan" comes twice a year.
"Higan" literally means other shore in Japanese. During this period, people often visit their family graves/cemeteries, offer flowers and some food called "Bota-mochi" or "Ohagi",
and pay respect to their ancestors.
I think I can say this O-higan of March as "Autumnal Equinox Day" here in South,
as it's autumn.
In association to the day, I cooked the traditional sweets "Ohagi"
(rice cake covered with sweet azuki beans paste)" of my favorite.
And some fusional ones, too.
