Tonjiru (豚汁)
The weather is getting colder and colder. One of the most popular foods to eat at such times is “tonjiru”. The unique flavor and texture of pork, which is different from chicken or beef, creates a deliciousness not found in traditional Japanese cuisine and never ceases to fascinate people. Tonjiru on a cold day is the ultimate treat.
What is Tonjiru?
Tonjiru (豚汁), also known as Butajiru, is a traditional Japanese soup made with pork and vegetables. The name itself reflects the key ingredient, as “ton” (豚) means pork, and “jiru” (汁) means soup. Locals prepared this hearty soup by simmering thinly sliced pork in a miso-based broth, along with various vegetables like daikon radish, carrots, potatoes, and onions. Some versions might also include tofu, konnyaku, or mushrooms. The rich and savory flavor of Tonjiru comes from the combination of miso paste and the natural sweetness of the vegetables and pork fat, making it a warming dish often enjoyed in colder months.
Tonjiru History
The history of Tonjiru (豚汁) is closely linked to Kagoshima Prefecture, a region famous for its pork. Kagoshima has the highest number of pigs in Japan, and its black pigs, known as “Kagoshima black pigs,” are a recognized brand. Despite meat-eating restrictions in the Edo period due to Buddhism, the Satsuma domain (modern-day Kagoshima) continued to consume pork, wild boar, and deer, partly due to its distance from Edo and influences from the Ryukyu trade. Shimazu Iehisa, a Satsuma commander, is said to have brought black pigs from Ryukyu, and over time, these pigs were crossbred with Berkshire pigs from England.
Kagoshima also produces barley miso, which is sweet and less salty, thanks to the warm climate. Dishes like “tonkotsu” (pork bone) and “tonmiso” (pork miso) reflect the region’s strong tradition of combining pork and miso.
Health Benefits of eating Tonjiru
Tonjiru offers several health benefits due to its nutritious ingredients. The pork provides a good source of protein, essential for muscle repair and overall body function, while the vegetables like daikon radish, carrots, and potatoes supply important vitamins, minerals, and fiber that support digestion and boost immunity. The miso used in Tonjiru is rich in probiotics, which promote gut health, and also contains antioxidants that help combat inflammation. Overall, Tonjiru is a balanced dish that combines protein, fiber, and beneficial nutrients in a warm, comforting meal.
What are the characteristics of tonjiru soup compared to other soups?
Use of Pork

Diverse Ingredients
A wide variety of vegetables are used in pork miso soup. The main ingredients include radishes, carrots, burdock root, and taros. Also often used are leeks, cabbage, Chinese cabbage, and potatoes. This variety of ingredients makes the dish rich in nutrients and can be enjoyed not simply as a side dish, but also as a simmered dish on its own.
