Non-smoking/Smoking separated Music Venues in Tokyo

Hello all! Sending good energy out to everyone in the sub :)

As my title hints at, my wife and I are looking for any live music venues in Tokyo that either are non-smoking or have a separated smoking section from the main floor (Where you don't have to walk through a smoking section that additionally allows smoke on the main floor).

My wife is pretty sensitive to cigarette smoke, fine if it is just in passing outside, but if it is in an enclosed room, she gets pretty nauseous.

So here I am. We really love Electronic Music (actual producers/DJ's, not generic club DJ's; Bass Music, Psytrance, Techno), Reggae Music, and Rock Music.

We will be in town from December 26 - Jan 13 and would really love to be able to hit a show or concert. Really wanted to go to Countdown Japan or Radwimps at Ariake but seems pretty impossible to get tickets as a foreigner that doesn't live in Japan.

Anyway, would really appreciate any and all recommendations you may have! If you know any shows happening during that date, would love to hear some recs as well!

Note: I have tried searching through Google and this sub (and others) but it is quite difficult to actually tell if a place is non-smoking/smoking separated.
