I think that most Japanese people are not religious, although we go to shrines or temples to pray for our good fortune, especially on New Year’s Day.
Why we do that? Maybe we are very superstitious. There are some examples you feel that we are very superstitious if you see them.
One example is “4”. We tend to hate “4”. Why? We pronounce “4” as “SHI” and this is the same pronunciation as “死” which means death. So “4” is often avoided using for room number at hospitals, hotels, apartments and so on – for example, there is sometimes no room 204.
We think that words have special power, although we don’t believe it completely. But we want to avoid using bad words if possible. You agree with me, right?
