Not just TAITO but the Wright Flyer Studios also started the Groove Coaster 3 Link Fever collaboration in the Shoumetsu Toshi smartphone game today.
Today (November 7) started the official Shoumetsu Toshi event in the arcade music game but you can get the official GC Navigator character in the Shoumetsu Toshi if you are lucky.

The official event stage also opened where you can try to grab some other GC character and you can listen during the play the new limited BGM the No more labor and the Endless Groove. The event will be held until November 24, 2016 so you can try to get the limited character until that day. Good luck!
