Non smoking bars/pubs ginza or tokyo area

Hi, I went to japan earlier in the year and plan to go back next year. I plan to go to Tokyo again but as I wont be flat out sightseeing as I saw so much last time I was wondering if there was any good pubs/bars in tokyo especially ginza as that is where I will be staying. I have already been to the good beer faucets in shibuya and would go back again but want to find something more local in ginza. I know it's a lot to ask but non smoking would be best. Thank you.

Here are some craft beer bars in the Ginza area: http://beerbarsjapan.com/dbinx/tr-ginza.html

And the Tokyo station area: http://beerbarsjapan.com/dbinx/tr-tokyo.html

I believe the chain of bars called Craft Beer Market are all non-smoking. And I-Brew has a non-smoking section, for what it's worth.

Do a yelp search with no-smoking filter.
Yes, Yelp!
While Yelp is not the most popular review site in Japan, it is starting to catch on. Some reviews are in Japanese, of course.

First: search for "bars" in "Ginza, Tokyo, Japan". When hundreds are listed, narrow down using filters. Click "All Filters", and under various features list is a smoking option. Click "No" for smoking, then hit "search".

Voila! I found a few that caught my interest. Cheers.

I tried Yelp, bars, Ginza, and you have to move the "distance" out to 8km ("driving") from Ginza before the non-smoking filter appears.

At 2km distance from Ginza ("walking") there are no beer bars listed at all, and only five bars altogether.

Forgot yelp even existed! I shall give it a try thanks.
