The comparison signifies the strong influence, guidance, and leadership roles that Anzai plays in his field, similar to that of a vice-principal in a school. He uses his visibility on television to inspire and educate others, transcending conventional boundaries of journalism and entertainment.
In Japan, news anchors and television personalities such as Anzai often have major influence among viewers and are perceived as authoritative figures. They frequently play roles beyond just delivering the news, often engaging in educational activities and helping shape public opinion on important matters. The comparison to a 'Kyotou sensei' emphasizes this role, showcasing not just Anzai’s popularity, but also his impact and responsibility.
In the US or EU, anchormen are respected journalists who deliver news but their roles usually stop there. While they can have influence, their roles are not typically seen as educational or mentor-like. Anzai's influential position is a unique aspect of Japanese culture where TV personalities often serve a wider societal role.
