Donald Trump, the former President of the United States, celebrated his 80th birthday with much fanfare, an event that didn't go unnoticed even in Japan. The celebration was held amidst unique and memorable set of circumstances, which caused the milestone to turn into an international spectacle, as marked by "異例ずくめ," or full of irregularities. Details about the celebration, Trump's political relevance, and its global impact are extensively covered in this news piece.
Japan, being an ally of the US, places great importance on having cordial relations and hence keenly observes major events related to prominent political figures. The people took an interest in the story due to Trump’s influence on global politics, especially during his presidency.
While such birthdays of prominent figures also gain significant attention in the US or EU, the level of scrutiny and discussion tends to be more contained within popular culture, and less in the field of journalism, compared to Japan, where it forms mainstream news.
