I found a pretty good Japanese grocery store in Livonia called Koyama Shoten. It is near the corner of Six Mile and Newburgh roads. I got a really nice mug and several food items for bento and sushi. I was pretty excited since almost all of the other Asian grocery stores in the area are Chinese or Korean. They tend to have only some of the items that I am usually looking for. They have limited bento items, but I scouted it out nonetheless.
