Zosui
Zosui (which is also called ojiya, a name considered to have originated from the Spanish word Olla) and Okayu, while similar, are two separate dishes. While the two dishes both contain rice, and both are traditionally eaten when people are feeling unwell, okayu is a kind of porridge (similar to oatmeal), while zosui is akin to a vegetable soup with lots of rice.
