I’m not sure it is regular rotation at Wadatsumi, they had a special sake one night and had a giant double bottle open on ice and selling by the glass. The waitress recommended we try it and we ended up drinking that all meal because it was so good and it went so well with their food. I went back a bit later and they didn’t have it anymore. 
I bought a couple bottles at HiTimes in Costa Mesa, but I believe they do not carry it regularly either.
