The impact of a series on international viewers' interest in Japanese culture can vary depending on the popularity and representation of Japanese culture within the series. If the series accurately portrays Japanese culture, traditions, and customs, it may increase international viewers' curiosity and interest in learning more about Japan. On the other hand, if the series misrepresents or stereotypes Japanese culture, it could potentially lead to misconceptions or misunderstandings. It's essential for series creators to be mindful of cultural sensitivity and authenticity when depicting Japanese culture to foster a positive impact on international viewers' perception and interest.
