The post-World War II era saw a significant shift in Japan's entertainment industry, as Western influences began to shape the country's popular culture. The 1960s and 1970s saw the emergence of J-Pop (Japanese popular music) and J-Rock (Japanese rock music), with artists like Kyu Sakamoto, known for his hit song "Ue o Muite Arukō" (also known as "Sukiyaki"), and rock bands like The Blue Comets and The Spiders.
