Why We Chose Dejima Asa

After trying Nagasaki’s famous specialties like champon and Toruko rice, we were eager to find a spot that locals actually love. In Japan, izakayas are often the best places to discover regional flavors, since they serve a wide range of small plates meant for sharing.

Dejima Asa promised exactly that, a lively atmosphere and plenty of dishes that would let us taste the authentic flavors of Nagasaki in one sitting.

What Is an Izakaya?

An izakaya is best described as a Japanese gastropub. These casual restaurants serve a mix of grilled skewers, fried snacks, sashimi, and seasonal specialties, along with drinks like sake and beer. It’s where locals gather after work, and it’s one of the best ways to experience everyday Japanese food culture.

Dining at Dejima Asa

Four pieces of golden-brown, breaded and fried Dejima Asa are arranged on a napkin, next to a halved cherry tomato, on a decorative blue and tan plate.

The restaurant had a welcoming, lively atmosphere. The dishes came quickly, and each one was wonderfully prepared.

What We Ordered and Loved

  • Kakuni (角煮): Tender braised pork belly simmered in sweet soy broth. A Nagasaki specialty with Chinese roots, it melted in our mouths.
  • Fish Paste in Fried Bread: Unusual but delicious—a warm bread pocket stuffed with savory fish paste, deep-fried until golden.
  • Grilled Squid Legs: Simply seasoned and perfectly charred, with a chewy texture that paired well with drinks.
  • Corn Kakiage (かき揚げ): A light tempura fritter of sweet corn kernels, crisp and naturally sweet.
  • Assorted Sashimi: Fresh, colorful, and beautifully presented without being overly formal.
