聖ニコラウス (Gift-Giver) is a historical figure known for his generosity and kindness. He was a 4th-century bishop in Myra, located in present-day Turkey. His acts of giving, especially to children and the needy, led to his reputation as a protector and benefactor. Over time, the legend of 聖ニコラウス evolved into the modern figure of Santa Claus. Celebrated on December 6th, his feast day, he is often associated with the spirit of giving and the tradition of gift-giving during the Christmas season.
