The J-Town Shopping Centre is a small complex made up of a few buildings; the most notable are Heisei Mart (a Japanese supermarket) and the food court. The supermarket carries mostly imported Japanese products. The food court consists of 2 sushi vendors, 2 bakeries, a wagyu specialty store, and a small restaurant selling mostly Japanese curry dishes, tonkatsu, and omurice.
The sushi & sashimi at the food court are super fresh. They have a wide variety of fish and seafood, including yellowtail, mackerel, squid, different cuts of tuna, uni, various fish roe (including my favourite, ikura). The bakery carries various Japanese buns (including the famous melon pan, buns filled with anko (red bean paste), etc.), sandwiches (e.g. yakisoba sandwich, fluffy egg sandwich), and some ready-to-eat hot food items (e.g. soba noodles, seared tuna salad, croquettes). The seared tuna salad was quite a hefty meal - 4-5 thick pieces of seared tuna, covered with black & white sesame seeds, sitting on top of a bed of quinoa, mixed beans, edamame, corn, cucumber, and cherry tomatoes. It made a very well-rounded and satisfying meal. The seafood croquette was great as well - crispy in the outside, soft and filled with umami in the inside (it had the consistency of mashed potato mixed with big pieces of seafood, including shrimps).
Although J-Mart may be small in size (both the supermarket and food court), it carries authentic Japanese products and fresh foods. There is even a takoyaki stand just outside, and a nice courtyard to be enjoyed in summer months. You know that a sushi place is authentic when the menu doesn't have 'Americanized' sushi rolls (California roll, dragon roll, etc.) - just the best and freshest sushi and sashimi selection.
