It's March 14 in Korea and here in Japan. Happy White Day
In Japan and Korea, Valentine's Day is a day for girls to show they like a boy.
The girls give gifts to the boys, like chocolate, candy, handmade gifts (usually letters) and other items
White Day is for boys to give gifts to girls to show their affections
March works well for older girls in Japan. The school year is over, so our oldest is spending most of the day with her b/f. They will go out and do "young people things" and she'll come back with who knows what. She's very excited, this is the second year they will do things on White Day and next school year (Year 3) they're seniors. Very exciting. Just ask her.
For the twins (junior high), one will spend the day with her friends (boys and girls) and the boys pay for everything. Back in February they went out on Sunday before Valentine's Day and the girls paid.
Our other twin will spend the day with her g/f. Last year her g/f bought her gifts on Valentine's Day and our daughter bought on White. This year they're switching. So today, she pays
For our youngest (elementary school - graduated 5th grade), they will hangout in groups with their friends. They will organize with their girl friends and meet up with the boys they like and they'll hangout together -- it's very discreet and provides plausible deniability
It's all very cute
Valentine's Day didn't become a thing here in Japan until the 70s.
White Day was a day invented by Ishimuramanseido, a candy company. Originally it was Marshmallow day and people gave marshmallow based gifts, white cookies or white chocolate to the girls.
Now the color doesn't matter and it's very common for older girls to get jewelry, boxes of candy and/or chocolate and spend the day with their b/fs and g/fs
For elementary school, they get food from some of the boys, more out of a feeling of obligation because the girls gave on Valentine's Day. Though, as I wrote earlier, older elementary school girls will sometimes hangout with a group of friends (boys and girls) that is made up of their girl friends and the boys each of them likes
