I was initially underwhelmed by the small size of the store, but I walked in and found that it had everything I was looking for.
In particular, I was looking for sashimi-grade fish and they had some tuna and salmon in stock. They also had uni and a couple of other fish that I did not recognize the Japanese name for.
I also picked up some sweet rice, an avocado, and some pocky sticks. It was pricey, but convenient, so I will be back.
