Yes, the Misukoshi store at Mitsukoshimae Station was selling it for 19,980 JPY
comparable to what is was here at the LCBO for CAD$216. I managed to get a few bottles at TPE. no discount codes on EVA when I was flying but I recall it was close to US$100....
decent price at Bevmo for the 12. As noted, I only saw yamazaki 12s in minis in Japan.
