This store has many of the brands I bought while living in Japan. You can get decent sushi rice, shiso salad dressing, miso, and even Pocky or shrimp snacks if you need a fix.
This is also the only place I've found in metro to sell the mesh strainers that fit in cups or pots to hold Japanese loose tea and suribachi, ceramic ridged mortars, wonderful for grinding spices or making sauces.
The woman owner who often works there is the epitome of Asian grace, charm and customer service. She even gave me a recipe for an unfamiliar Korean ingredient. Highly recommended!
