One of the oldest processed foods of South-east Asia, tofu has become more widely appreciated in recent years due to health-conscious trends around the world. Tofu came to Japan from China in the 8th century and has been one of the most important foods ever since.
As with many other foods, the Japanese developed tofu to a more refined form, as well as producing many new by-products to suit the subtlety and delicacy of Japanese cooking. Tofu is mostly made commercially nowadays, but there are still small tofu-making businesses in many residential areas of Japan, making fresh tofu at dawn everyday.
