The news revolves around a politician, presumably Takaichi Sanae, who is being accused of orchestrating a wave of anonymous praises on social media. The accusations argue that these messages support his campaign in an unsportsmanlike manner. Takaichi's side, however, has completely denied these allegations.
In Japan, it's unusual and frowned upon for politicians to create orchestrated social media campaigns for self-praise and manipulation. Traditional campaign methods are more acceptable, and information manipulation is considered to be a high deviation from customary political norms. The typical Japanese values of integrity and respect play a larger role in politics in comparison to many Western countries.
In contrast, in the US and EU, social media plays a crucial role in shaping political campaigns and outcomes. Positive as well as negative online campaigns are more common while avoiding any direct violations of election laws. Politicians are also more forthright and aggressive in their campaigning strategies, which often include well planned disinformation or smear campaigns.
