Yamaguchi's Uiro: A Steamed Rice Sweet With Old Roots

Uiro is a steamed cake made from rice flour and sugar, with a dense, slightly chewy texture closer to mochi than to Western cake. While Nagoya is the city most associated with uiro today, Yamaguchi has its own long-standing tradition, tied to the Ouchi clan's rule over the region during the medieval period, when the area had extensive trade contact with continental Asia that historians credit with introducing early versions of the confection.

Yamaguchi-style uiro tends to be softer and more delicately flavored than some other regional versions, often flavored simply with brown sugar, matcha, or kuromame (black soybean) rather than heavily sweetened. It's typically sold in small block or bar form, sliced for serving, and makes a common, not-too-sweet souvenir. As with any small regional confection, exact recipes and texture vary between makers, so trying a couple of shops' versions gives a better sense of the range.
