Kazunari Ninomiya shared a post on his official X account revealing that he celebrated the Arashi's 27th debut anniversary with fellow members on November 3.

The date marks the anniversary of Arashi's debut single, "A・RA・SHI," released in 1999.

Ninomiya posted a photo showing three people raising their glasses in a toast, along with the caption, "Real Arashi gathering activated. (Oldest, youngest, youngest)." The caption appears to refer to Satoshi Ohno, Ninomiya, and Jun Matsumoto, based on the members' ages.

The post drew an enthusiastic response from fans, many of whom celebrated the group's anniversary and expressed their excitement over the reunion.
