NewJeans has yet to officially debut in Japan but their popularity is already through the roof. 

On August 19th, NewJeans performed on the main stage at one of Japan's largest music festivals, 'Summer Sonic,' in Tokyo. Despite the early time of their performance at noon, 'Summer Sonic' had to limit the entrance of the additional audience as many flocked over to the main stage to see the girl group's performance. 

Stay tuned for what NewJeans has in store for its fans all over the world.
