Gyoza no Ohsho began in Japan.
Gyoza no Ohsho is a Japanese restaurant chain specializing in gyoza and other dishes associated with Japanese Chinese cuisine. Its first restaurant opened in Shijō–Ōmiya, Kyoto, and the company was founded in 1967. The chain’s corporate identity and restaurant network are therefore rooted in Japan, not in one of the neighboring countries listed as alternatives.
The name means roughly “King of Gyoza,” combining gyoza with ōshō, a Japanese term associated with a king or champion. Restaurants offer a standardized menu, while individual locations may also serve locally tailored set meals. The chain grew into a major domestic brand with hundreds of restaurants across Japan.
Gyoza itself has Chinese origins, which can cause confusion about the answer. Japan adapted jiaozi into gyōza, especially the crisp-bottomed, pan-fried style commonly served with ramen or rice. That Chinese culinary ancestry does not change the country where this particular restaurant chain began.
The company later pursued overseas expansion, including a store in Kaohsiung, Taiwan, but those international locations came after its Japanese founding.
