" White Day is from Hakata, Japan! "
Well-known Valentine's Day comes from ancient Rome, but only a few people in Japan probably know that White Day is from modern Hakata, Japan.

White Day has been becoming more popular in Japan for several decades. On the Valentine's Day all guys who are given something nice or chocolate by their girl friends unconditionally have to return something better after one month, on March 14 in Japan.

Such a unique custom which has become firmly established among the Japanese was produced by a Hakata great merchant running a confectionery " Ishimura-Manseido " in 1977. In those days it seemed it was called Marshmallow Day.

On that background I'm sure that Hakata merchants have had own their traditional wisdom since ancient Azuchi-Momoyama period.
