An annual plant native to the Andes of South America. The red ripe fruit is rich in lycopene and vitamin C, and is a staple ingredient in Western cuisine for salads, pasta, and ketchup. Introduced to Japan during the Edo period, it became widely consumed only after the Meiji era. Japan's greenhouse cultivation technology produces high-quality domestic tomatoes.
