I have been to J-town a few times, I think the last time was in 2014. From what I remember, it had a few good Japanese restaurants where you could get Japanese style curry and Japanese style pasta as well as other dishes. The place also had a really cute Japanese bakery within a grocery store which sold inexpensive delicious goods. Lastly, there was a section for Japanese beauty, stationery, and kitchenware although I found those to be ridiculously overpriced.
