was originally a word cognate to Old Japanese 'deity'. The Jeju language is Koreanic, but may have a Japonic substratum. For example, the colloquial word 'mouth' may be connected to the Japonic word 'mouth'. Proposed archaeological links Most linguists studying the Japonic family believe that it was brought to the Japanese archipelago from the Korean peninsula around 700–300 BCE by wet-rice farmers of the Yayoi culture. Whitman and Miyamoto associate Japonic on the Korean peninsula with the Mumun culture, which introduced wet-rice agriculture around 1500 BCE. In addition to rice, the onset of the Yayoi culture in northern Kyushu saw the introduction and adaptation of many cultural features from the Korean Mumun culture, including types of housing, pottery and tools. Archaeologists believe this reflects a combination of diffusion, migration from the peninsula, and hybridisation within the archipelago. Whitman further suggests that Koreanic arrived in the peninsula from the north with the Liaoning bronze dagger culture about 300 BCE. Vovin and James Marshall Unger propose similar models, but associate Koreanic with iron-using mounted warriors from Manchuria. In contrast, Juha Janhunen argues that Koreanic expanded from Silla in the southeast, replacing Japonic languages in Baekje and the rest of the peninsula.
