Yoshinoya (𠮷野家) is a Japanese multinational fast food chain, and the second-largest chain of gyūdon restaurants. The chain was established in Japan in 1899. Its motto is "Tasty, low-priced, and quick".

Gyūdon , also known as gyūmeshi , is a Japanese dish consisting of a bowl of rice topped with beef and onion simmered in a mildly sweet sauce flavored with dashi, soy sauce and mirin. It may sometimes also be served with toppings such as raw or soft poached eggs, Welsh onions (negi), grated cheese or kimchi. A popular food in Japan, it is commonly eaten with beni shōga, shichimi, and a side dish of miso soup.
