How to say "Merry Christmas" in Japanese?

Merry Christmas translated into Japanese is メリクリスマス.

Christmas is now a global holiday, and all countries, whether they believe in Christianity or not, will celebrate Christmas. All countries have their own Christmas characteristics. The United States and Britain, which traditionally celebrate Christmas, will take a long vacation to celebrate the whole country, and Asian countries such as Japan and South Korea will follow suit.

In Japan, South Korea and other Asian countries, although people don't believe in Christianity, Christmas is an excellent shopping spree day. Domestic businesses will hold promotional activities at this stage, especially duty-free shops, pharmacies and large supermarkets, almost all of which are crowded with people. At night, the colorful lights lit up in major shopping malls are also very intoxicating. There is also a popular saying in Japan that when you go to the Tokyo Tower at Christmas, you will hold hands for a lifetime, so countless couples gather under the Tokyo Tower every Christmas.
