I asked for a typical J-Winter ballad and J-boy band Deep delivered to the template and didn't skip a beat. A piano opening, strings, a sombre mood, some wails and lots of snow and fur coats in the video. "Snow shizuri" is as typical as a J-Winter ballad can get. I am a sucker for these types of songs, even though they all sound exactly the same.
Deep were originally formed and produced by EXILE member Atsushi, who was also a part of the group with two other members - at this point the group was named Color. But Atsushi and two other guys left, new members came in and the group name changed. We know how Japan rolls with groups. They switch people in-n-out and keep it moving.
