Uirō (外郎) is a traditional Japanese steamed cake made of rice flour and sugar. It is chewy, similar to mochi, and subtly sweet. Flavors, among others, include azuki bean paste, green tea (matcha), yuzu, strawberry and chestnut. Nagoya is particularly famous for its uirō, but there are other regional versions as well as it can also be purchased in traditional Japanese confectionery shops throughout Japan.
