In Japanese culture, the number 4 is considered to be unlucky. This belief stems from the fact that the word for four, "shi," sounds very similar to the word for death in Japanese. As a result, many buildings in Japan do not have a fourth floor, and gifts are often given in sets of three or five to avoid the number four. The fear of the number 4, known as tetraphobia, is so ingrained in Japanese society that it has had a significant impact on various aspects of daily life. For example, some hospitals and hotels skip room numbers containing the number 4, and many people avoid scheduling important events on the 4th day of the month. This superstition surrounding the number 4 is not unique to Japan. In many East Asian countries, including China and South Korea, the number 4 is also considered unlucky for similar linguistic reasons. This cultural belief has even influenced the design of products and services in these regions. Despite the prevalence of tetraphobia in Japanese culture, it is important to remember that superstitions and beliefs about luck vary greatly from one culture to another. What may be considered unlucky in one society may hold no significance in another. For more information on the cultural significance of numbers in Japan, you can visit Japan Guide.
