One of Oita’s healthier famous foods, jigoku mushi is food that has been steam cooked using the local hot spring water and can include seasonal vegetables, seafood, chicken, eggs and more. Some of the most popular options are eggs, steamed pork buns, and custard pudding. At most places this is a hand- on experience. You select and pay for your food at a ticket machine and the staff walk you through cooking your food and setting the appropriate timer. Keep in mind some venues will ask you to pay a one off basket rental fee while others will ask for a basket per a certain number of dishes. Some venues also just offer the jigoku mushi facilities – allowing you to bring your own food from outside.
