On July 17, SoftBank announced the launch of the project "Deliver Your Voice! Arashi and the '5G Virtual Grand Chorus'" to explore new entertainment possibilities for the 5G (fifth-generation communication system) era.

The first installment is a participatory project themed "Together, to a world no one has ever seen," collaborating with the nationally popular group Arashi. Fans will virtually sing along to their hit song "Love so sweet." Selected singing videos submitted by fans will be combined with footage of Arashi and used in a new TV commercial scheduled to air from early August.
Additionally, all applicants will receive a URL to view an original video incorporating their footage, regardless of whether it is used in the commercial.
Those wishing to participate should film themselves singing the song and submit their entry via the special website ( https://www.softbank.jp/mobile/special/neverseen/ ) between 8:00 PM on July 18 and 3:59 AM on July 22.
The company advises that while the site may experience congestion and longer wait times immediately after the application period opens, the timing of submission does not affect the selection process, so participants are encouraged to apply at different times within the period.
Member Jun Matsumoto stated, "I'm delighted to start this project with the company. I feel 5G holds the potential to create new experiences and forms of communication. I want to take on various challenges so fans can enjoy new entertainment utilizing SoftBank's 5G technology," calling for participation in the project.
