Christmas is celebrated in Japan on December 25th, just like in many other countries. However, the way Christmas is celebrated in Japan is very different from how it's celebrated in the West. In Japan, Christmas is often seen as a romantic holiday, and many couples go out for dinner or exchange gifts. Many Japanese people also decorate their homes and businesses with Christmas decorations, but it's not as big of a deal as it is in other countries. Instead, New Year's Eve is the more important holiday in Japan, when people gather with their families and friends to celebrate the beginning of the new year.
