They stated they are preparing for a fun performance.
This performance comes as they gain rapid popularity in Japan.
The group LE SSERAFIM is set to perform at the renowned music festival Summer Sonic 2026 in Japan this August. This festival hosts a variety of global artists and is recognized as Asia's largest urban music festival, taking place from August 14 to 16 at venues such as the Chiba Marine Stadium in Tokyo and the Osaka Expo Memorial Park. LE SSERAFIM will showcase their talents during select performances, with further details to be revealed soon.
In a statement, SOESMUSIC expressed excitement, stating, “Since this is our first time participating in 'Summer Sonic', we are preparing diligently to share enjoyable moments with our audience. We are particularly excited to perform in both Tokyo and Osaka and look forward to delivering a performance that everyone can enjoy.”
LE SSERAFIM's participation is a testament to their rising popularity in Japan. Their single ‘SPAGHETTI’, released last October, surpassed 100,000 shipments within just four days after its release. This achievement made them the first K-pop girl group of the fourth generation to receive the Japan Record Association’s Gold Disk certification for five consecutive albums. Additionally, last November, they made their Tokyo Dome debut with the ‘2025 LE SSERAFIM TOUR ‘EASY CRAZY HOT’ ENCORE IN TOKYO DOME', attracting around 80,000 attendees over two shows.
LE SSERAFIM's participation in Summer Sonic marks a significant milestone in the global expansion of K-pop. With their continuous album releases and distinctive musical style, they have steadily broadened their fan base in Japan, and this performance is likely to further solidify their popularity in the region.
In particular, ‘SPAGHETTI’ serves as a pivotal moment that showcases their musical growth and influence within the Japanese market. The 100,000 sales reflect the support from their fans and underscore Japan's keen interest in K-pop.
Moreover, leveraging their Tokyo Dome experience, LE SSERAFIM is expected to deliver exceptional performances at Summer Sonic, enhancing their rapport with fans and potentially expanding their global fandom even further.
