In the quest to fill up on frozen taiyaki, I found a few "Japanese" stores and restaurants, and none I've seen so far belong to Japanese. Sumo Sushi in Downtown is ran by Chinese, little store at Wyoming is Korean, etc.. I guess it would not be weird for me to open a Japanese store then. Maybe the cross-over is the Albuquerque way. On the other hand, Red Square at Lomas is run by Russians.
