Gyoza: the Japanese dumpling that isn't Chinese

Gyoza (餃子) arrived in Japan from China during the twentieth century, mainly through soldiers returning from Manchuria after the Second World War. But what happened next follows the usual Japanese pattern: the recipe was transformed into something with its own identity, with cooking techniques, flavours, and rituals that clearly distinguish it from the Chinese jiaozi it came from.

Japanese gyoza vs Chinese jiaozi

The differences are several. Japanese gyoza dough is thinner and more delicate than jiaozi dough. The filling contains minced pork, Chinese cabbage (hakusai), garlic chives (nira), garlic, and ginger — more aromatic and garlicky than the Chinese original. The cabbage is added raw or lightly squeezed, which gives the filling more moisture and a fresh note.

The most visible difference is the cooking method. The most common gyoza in Japan is yaki-gyoza (焼き餃子): pan-fried flat-side down in oil until crispy and golden, then water is added and the pan covered so the top steams. The result is a dumpling with one crispy face and the rest soft — that combination is what makes it so hard to eat just three.

The three ways to cook it

Yaki-gyoza (焼き餃子): pan-fried then steamed. The most common, and what most people think of as Japanese gyoza.

Sui-gyoza (水餃子): boiled in water, closer to the original jiaozi. Less common in restaurants but standard at home and in some specialist places.

Age-gyoza (揚げ餃子): deep-fried in oil, completely crispy. Less common but available at some restaurants as a variation.

The standard dipping sauce is a mix of soy sauce and rice vinegar (ponzu), with chilli oil (rayu, 辣油) to taste. The rayu is optional but highly recommended — the gentle heat complements the pork fat well. Each person mixes their own ratio in the small bowl the server usually brings empty to the table.

The Utsunomiya vs Hamamatsu rivalry

Japan has a fairly serious gyoza geography. Two cities compete for the title of national gyoza capital:

Utsunomiya (Tochigi, north of Tokyo): the city with the highest per-capita gyoza consumption in the country according to government statistics. It has a concentration of specialist gyoza restaurants around the station and in the central district. The Utsunomiya version tends to be smaller and more heavily garlicked.

Hamamatsu (Shizuoka, between Tokyo and Osaka): the rival. The Hamamatsu version is larger, with a filling that includes onion rather than cabbage, and is served with bean sprouts in the centre of the plate. It also contests the top per-capita consumption spot with Utsunomiya.

A third city that some add to the debate is Osaka, where gyoza tends to be thinner and lighter than the eastern Japan versions.

Gyoza at izakaya and ramen restaurants

Gyoza is one of the most universal dishes in Japanese casual dining. It appears as a shared plate at almost every izakaya, usually in portions of six pieces. At ramen restaurants it is the classic side — ordering a bowl of ramen and a plate of gyoza is one of the most satisfying and affordable lunches in Japan.

The chains Ohsho (王将) and Gyoza no Ohsho are the benchmark for decent quality at low prices across the country. A plate of six gyoza costs around ¥300–350. For something more serious, the specialist gyoza restaurants in Utsunomiya or small chuka (中華) spots with homemade gyoza are the best option.

Frozen gyoza: the Ajinomoto phenomenon

Worth mentioning: Ajinomoto frozen gyoza is one of the best-selling products in Japan. It is cooked in a dry pan with no oil or water (the gyoza’s own moisture is enough) and the result is hard to distinguish from many restaurants. If you live in Japan or have access to a Japanese supermarket, it is worth trying.
