Mitsuwa Marketplace in Irvine serves the local community as a Japanese-focused grocery store located in Heritage Plaza. The store centers on imported Japanese foodstuffs and everyday cooking ingredients, with aisles organized around pantry staples such as Japanese rice, dried noodles, miso, soy sauces, and curry bases.
The produce section is modest in size but includes items commonly used in Japanese home cooking alongside standard fruits and vegetables. Nearby refrigerated cases carry fresh tofu, chilled prepared sides, and ready-to-eat sushi and onigiri. The seafood counter offers fresh fish and sashimi-grade selections, while the meat section carries thin-sliced cuts suitable for grilling and hot pot dishes.
Packaged Japanese snacks and sweets line several aisles, along with bottled Japanese teas and soft drinks. Frozen cases hold prepared items such as dumplings and other quick-cook foods.
Within the same footprint, customers can also purchase bento boxes and chilled prepared meals. Toward the back of the space, a compact food court area allows shoppers to order hot dishes after finishing their grocery shopping, and bakery and confectionery counters near the entrance provide Japanese-style baked goods and desserts.
