Pixel-art imaginary scene of A sourced guide to food and harbor life in Nagasaki City, using Nagasaki Chinatown as a local clue

Nagasaki's dinner table carries traces of both Edo-period trade and modern shipbuilding. This guide traces individual dishes and landmarks — from a Portuguese sponge cake to a noodle soup invented for Chinese students — back to their origins.

Nagasaki's food culture blends three distinct strands: Portuguese, Chinese, and Japanese. Castella arrived with Portuguese traders, while champon was invented specifically for Chinese exchange students living in the city.

This article walks through eight names — Nagasaki Chinatown, Castella, Nagasaki champon, Sara udon, Kakuni manju, Mitsubishi Nagasaki Shipyard, Sofukuji Temple, and Kofukuji Temple — with the dates, founders, and shops behind each one.

Food and harbor life: Nagasaki Chinatown and Castella

Nagasaki Chinatown grew out of an Edo-period landfill once settled by residents of the Chinese quarter, while Castella descends from a Portuguese sponge cake introduced in the 16th century — two names with very different starting points.

Nagasaki Chinatown

A Chinatown that grew on reclaimed land

The district now known as Nagasaki Chinatown began as Shinchigura, a landfill built during the Edo period. As Chinese residents outgrew the government-designated Chinese quarter, Tojin Yashiki, some moved into this reclaimed area, and the neighborhood gradually filled with Chinese restaurants and grocers. Today it ranks alongside Yokohama Chinatown and Kobe Nankinmachi as one of Japan's three major Chinatowns.

Castella

A Portuguese sponge cake

Castella traces back to pao de lo, a cake Portuguese traders brought to Nagasaki in the 16th century. The basic method of eggs, flour, and sugar was passed down through local confectioners, giving rise to shops still open today, including Fukusaya, founded in 1624, and Shooken, founded in 1681. Unlike Nagasaki Chinatown, which names a whole neighborhood, Castella refers to a single product.

Food and harbor life: Nagasaki champon and Sara udon

Nagasaki champon is served in a cloudy pork-and-chicken broth over thick noodles, while Sara udon ladles the same kind of ingredients as a thickened sauce over noodles with little or no broth — that difference in liquid is the quickest way to tell them apart.

Nagasaki champon

A noodle dish invented in the Meiji era

Champon is credited to Chin Heijun, the founding chef of the restaurant Shikairo, opened in 1899. He designed it as an inexpensive, nutritious meal for Chinese students studying in Nagasaki. The dish combines a cloudy broth made from pork and chicken bones with thick noodles and a generous mix of seafood and vegetables, packing a full meal into one bowl.

Sara udon

A fried-noodle dish descended from champon

Sara udon is traditionally traced to the same Shikairo lineage as champon, but instead of a full broth it tops the noodles with a thickened sauce carrying the same seafood and vegetables. Despite the name, it uses Chinese-style noodles rather than udon wheat noodles — some shops serve it over thick, soft noodles, others over noodles fried crisp.

Food and harbor life: Kakuni manju and Mitsubishi Nagasaki Shipyard

Kakuni manju is a street-food bun filled with the braised pork belly served in Nagasaki's shippoku cuisine, while Mitsubishi Nagasaki Shipyard traces back to an ironworks the shogunate opened in the 1850s.

Kakuni manju

A street-food bun built on shippoku cuisine

Kakuni manju tucks the braised pork belly, kakuni, served at Nagasaki's shippoku banquets into a soft steamed bun, turning a banquet dish into food you can eat while walking. Several shops, including Iwasaki Honpo, sell it as a signature item, and it has become a common snack for visitors strolling near Chinatown or Meganebashi Bridge.

Mitsubishi Nagasaki Shipyard

A shipyard descended from a shogunate-era ironworks

The shipyard's history begins with the Nagasaki Ironworks, opened by the Tokugawa shogunate in 1857. Mitsubishi took over its operation in 1884, and the yard grew into one of Japan's leading shipbuilders. During the Second World War, in 1942, it built the battleship Musashi, and related facilities became part of a UNESCO World Heritage listing in 2015.

Food and harbor life: Sofukuji Temple and Kofukuji Temple

Sofukuji Temple was built in 1629 by Chinese merchants from Fujian, while Kofukuji Temple, founded in 1620, was Japan's first Chinese-style temple and became the birthplace of Japanese Obaku Zen.

Sofukuji Temple

A Chinese-style temple built by Fujian merchants

Sofukuji Temple was built in 1629 by Chinese merchants from Fujian province, following the architectural style of their home region. Chinese craftsmen and materials were brought over for the project, and both the Daiyuhoden hall and the temple gate are now designated National Treasures, their vermilion woodwork keeping the look of southern Chinese temple architecture.

Kofukuji Temple

Japan's first Chinese-style temple

Kofukuji Temple was founded in 1620, making it older than Sofukuji and generally regarded as Japan's first Chinese-style temple. In 1654 the Chinese monk Yinyuan Longqi, known in Japan as Ingen Ryuki, arrived and took up residence here before spreading the Obaku school of Zen Buddhism across the country, which is why Kofukuji is considered the birthplace of Japanese Obaku Zen.

FAQ

For look-alike pairs like champon and Sara udon, one detail — whether the dish comes in broth or with a thickened sauce — is often enough to tell them apart on the spot.
