I believe what some of you're looking for is a trendy, perhaps up-scale restaurant experience... which this clearly is not.
It's quite authentic however, which is what gives it it's appeal.
I've lived in Japan and have been all over the Tokyo metropolitan area, this place may not have extravagant presentation (Japan is known for it's minimalism, thus their cuisine tends to be simple but highly refined and perfectly prepared)... but it is very Japanese.
Again, there is better, but I have been to many habachi-style (which is not found in Japan) locations in the greater Richmond area (Kobe, Yamato, Sakura, Kabuto, Tenjimura, etc.) as well as a few more traditional types (Akida, Wasabi, Soya, Carytown Sushi, among others), and although this place is 45 mins from where I live I still consider going here for that authentic experience.
There are places in Richmond which as far as the cuisine goes, are just as authentic, but of better quality and the atmosphere is much more ambient and comfortable. I always opt to go to these places instead.
Two places I'd highly recommend are Carytown Sushi and Soya.
Pros: authentic, decent food
Cons: poor menu selection, poor music
