The main area has 2 grocery store areas, a bakery, and 2 diner-type restaurants. There are all kinds of trinkets and little household items on sale. There are also places to shop for clothes, appliances, books etc. Also very close to another izakaya and restaurant.
The 2 main drawbacks are that the items are overpriced and selection is very limited. It feels nothing like Japan, other than some authentic foods. In fact since so few people buy the random trinkets I feel they're almost dusty and easily hasn't changed in 10 years. Somehow simple household groceries are expensive, like selling juice for 6.99 when the Chinese grocery stores sell 4.99 for an identical carton. If you're looking for snacks and imported goods try Pacific Mall or T&T.
The only redeeming facts are the small diners which has delicious sushi and home style cooking. Great lunch spot.
