5 Famous Foods You’ll Find in Nagasaki

As a port city with centuries of overseas influence, Nagasaki offers one of Japan’s most diverse regional cuisines. From the hearty noodle bowls brought by Chinese immigrants to European-inspired cakes and American-style burgers, every dish reflects the city’s cultural influences. Here are five famous foods in Nagasaki.

1. Champon

This hearty noodle soup is packed with pork, seafood and vegetables. Champon originated in Nagasaki’s Chinese quarter in the late 19th century as an affordable, nutritious meal for Chinese students studying and working in Japan. The noodles are cooked directly in a rich pork-and-chicken broth, giving the dish a comforting, savory depth. It’s warm, filling and affordable. This local favorite is a staple at casual eateries and long-established Chinese restaurants. Every shop has its own take, but the deliciousness of Champon lies in its rich broth and generous toppings. For an authentic experience, try it at Shikairo, the restaurant where it was first invented.

2. Sara Udon

Despite the name, sara udon (plate udon) doesn’t use udon noodles. Instead, it typically features either thin, crispy-fried noodles that shatter with each bite or thicker, softer ones similar to champon noodles. These are topped with a colorful stir-fry of pork, shrimp, squid, cabbage, bean sprouts and other seasonal vegetables, all coated in a glossy, umami-rich sauce made with soy and chicken stock.

Originating from Nagasaki’s Chinese culinary heritage, it’s a variation of champon, offering the same savory goodness but with more texture. It’s a favorite among locals and a must-try for anyone who enjoys the contrast between crunchy noodles and silky toppings. Many restaurants in Nagasaki let you choose your noodle style, so come hungry and curious.

3. Castella

Introduced by Portuguese traders in the 16th century, castella is a moist, honey-flavored sponge cake that’s become a signature sweet of Nagasaki. Made with just sugar, flour, eggs and starch syrup, it’s deceptively simple but incredibly satisfying. You’ll find many varieties of Castella sold in souvenir shops throughout the city. Occasionally, you might find Nagasaki Castella sold at popular supermarkets, like Aeon, around Japan. 

4. Sasebo Burger

An American-style burger with a Japanese twist. The Sasebo Burger was born near the U.S. Navy base in Sasebo City after World War II, when local shops began recreating American-style hamburgers for stationed soldiers. These burgers come in all sizes and styles and a variety of sauces.

The emphasis is on quality and freshness and many shops pride themselves on using local ingredients and baking their buns in-house. Some versions are towering creations that require two hands and a serious appetite. 

5. Kakuni Manju

This street-food favorite features a manju (steamed bun) stuffed with kakuni (braised pork belly). The pork is rich, savory and slightly sweet. Popular at festivals and local shops (Dejima and Chinatown), it’s a must-try when strolling Nagasaki’s historic neighborhoods.
