The number of people who believe in this religion is very large, and it is said that there are more than 1 billion people in the world.
Most people who believe in Christianity are in the U.S. and Europe, and Japan is not a country with that many people.
Christmas is the birthday of Jesus Christ, who started this Christianity. Although Jesus Christ was born almost 2,000 years ago, people who believe in Christianity still celebrate his birthday every year by having Christmas.
In other words, Christmas is really a festival that has nothing to do with those who do not believe in Christianity.
However, Japanese people love festivals. Even though it has nothing to do with Jesus Christ, everyone has somehow come to celebrate Christmas.
However, the Japanese way of celebrating Christmas is quite different from others. For those who believe in Christianity, Christmas is celebrated in a rather simple way, with a trip to church and a meal with the family inside the house.
