In the first place, my feeling is that in the ancient times there were only very simple curses, and that they were popular during the Nara and Heian periods, but had already declined in the armed society after the Kamakura period. More specifically, faith and religion have existed in people's hearts from the beginning of time to the present day, and have been a force that moves society, and they have also been strongly linked to curses, and Tendai Buddhism also has elements of esoteric Buddhism. However, I think it is fair to say that people today, in a world where science is flourishing, generally do not believe in the power of curses.
By the way, the photo on the top right was actually taken recently (several years ago from 2010). I can't deny the possibility that the subject was a prank, but I don't think that's the case after all. Even if you think in your head that there is no such thing as a curse, don't you think that you can't be sure that there are no people whose hearts turn to deep sadness, hatred, and resentment due to poor health, misfortune, and unhappiness? (I can't say for sure that being cursed like this doesn't bother me). People who can say that are very healthy and happy. This photo made me think that whether spirituality and inspiration are supported by television stations or not, deep within people's hearts, such things that have been cultivated through history remain without degenerating or evolving.
