Who Are King & Prince?

If you’re new to Japanese idols, King & Prince might just steal your heart. Formed in 2018 under Johnny’s Universe (part of Universal Music), they exploded onto the scene with their debut single シンデレラガール (Shinderera Gaaru - Cinderella Girl). Since then, they’ve been unstoppable, releasing chart-topping hits and even holding their first dome tour in 2022. After a lineup change in 2023, the group now consists of Nagase Ren and Takahashi Kaito, who continue to embody the spirit of アイドル (aidoru - idol) culture. Their journey showcases the resilience and adaptability at the core of this industry, making them a perfect starting point for exploring Japanese entertainment.

Cultural Context: The Heart of J-Pop Idol Culture

To truly appreciate King & Prince, you’ll need to understand アイドル文化 (aidoru bunka - idol culture), a phenomenon that sets Japanese entertainment apart.

Managed by agencies like STARTO ENTERTAINMENT, groups like King & Prince focus heavily on fan engagement through events, exclusive content, and massive concerts. Their music often blends upbeat pop with emotional ballads, touching on themes like dreams and perseverance that resonate deeply in Japanese society. The 公開 (koukai - release) of a song like Theater isn’t just a drop; it’s a cultural event, especially with its timing around the Christmas season, a peak moment for entertainment in Japan.
