Best Japanese/Sushi in Calgary?
In my opinion the best expression of authentic Japanese cuisine in Calgary is Sushi Bar Zipang on 1st Ave. in Bridgeland. I have had multiple great experiences there over the years. My only caution is the price; it is not cheap. But it is worth it.

My current rotation is O Shima/El's Japanese Fusion/Midori, but I've had good to great experiences at Uptown, Blowfish, Towa, a TINY little space in the DT west end called Sushi and Co., Tenshi, Sushi Club, Globefish, Ren's (used to be Sushi on Richmond) and Sukiyaki House. The only places I actively avoid are Tokyo Sushi and Fuji Yama though I might not be giving the latter a fair shake.
I like O Shima for its elegant nigiri, El's for its insanely over-the-top Korean fusion rolls, and Midori as a sort of cheaper version of El's.
Oh, and for non-sushi Japanese- the best teriyaki I've ever had-- anywhere-- is at Banzai downtown near 4th and 4th SW. 100% Japanese staff and just amazing teriyaki and bento combos. I also live right by a place called Oishii that has one of my favourite dishes; it's tempura tuna don, with tempura broccoli. Never had it anywhere else.
There are TONS of places outside of my mostly inner-Southwest focus.
