Buddhist cuisine is an Asian cuisine that is followed by monks and many believers from areas historically influenced by Mahayana Buddhism. It is vegetarian or vegan, and it is based on the Dharmic concept of ahimsa (non-violence). Vegetarianism is common in other Dharmic faiths such as Hinduism, Jainism and Sikhism, as well as East Asian religions like Taoism. While monks, nuns and a minority of believers are vegetarian year-round, many believers follow the Buddhist vegetarian diet for celebrations.

The Ōbaku-shū (黄檗宗) is one of three main schools of Zen in Japanese Buddhism, in addition to Sōtō and Rinzai. It had a strong influence on Japanese Rinzai, which partly adopted Ōbaku-practices, and partly reinstored older practices in response to the Ōbaku-school.
