Ayase from YOASOBI is stepping into the radio booth for a meaningful conversation with King Gnu's bassist Arase on J-WAVE's "SPARK" program airing tonight at midnight. While the two have crossed paths at industry events before, this marks their first real chance to dig into each other's work and perspectives.

Arase hosts the "SPARK" show Tuesday through Thursday nights, and he's bringing Ayase in to break past the typical quick hellos that happen backstage. The two are close in age and operate in similar creative circles within Japan's music scene, but they've never had a proper sit-down discussion. Tonight's episode will feature them comparing notes on their current projects and swapping first impressions of each other's careers.

The show also features a special "Ayase Bias Tournament" segment—a twist on the program's popular "Bias Championship" corner. This version invites listeners to submit their preconceived notions about Ayase, which then become the jumping-off point for lighthearted banter and conversation.

Ayase has become one of Japan's most recognizable figures since YOASOBI's 2019 debut with "Yoru ni Kakeru." The track exploded globally and claimed the top spot on Billboard Japan's year-end Hot 100 for 2020. Their 2023 single "Idol," which serves as the opening theme for the anime Oshi no Ko, made history as the first J-Pop song to hit number one on multiple international charts simultaneously, including Billboard's Global Excl. U.S. chart and Apple Music's global rankings.

Ayase recently wrapped up YOASOBI's 2024 dome tour, which sold out shows in Osaka and Tokyo. King Gnu, meanwhile, continues to build momentum with their own touring and appearances. This radio appearance gives fans a rare peek at the personalities behind two of the country's most innovative modern acts.

The "SPARK" episode airs June 9 at midnight on J-WAVE, with replay access available through radiko's time-free feature for one week after broadcast.
