I happen to catch an Oct 2017 episode of Music Station recently. Only then did it dawn on me that I have been a fan of arashi for exactly 10 years this year!
I had that feeling that it would be sooner or later... esp when they already have so many solo activities. tbh, I don't follow them that closely but based on a few quick observations, it seems so... ?
Whatever their future decision is, I wish them success in their new paths.
