The post-World War II era saw a significant shift in Japan's entertainment industry, with the introduction of Western-style music, film, and television. Japanese pop music, or J-pop, emerged in the 1960s, with artists like Kyu Sakamoto, who gained international recognition with his hit song "Ue o Muite Arukō" (also known as "Sukiyaki"). The 1980s saw the rise of Japanese rock music, with bands like The Blue Hearts and X Japan achieving widespread popularity.
