Japonic languages are a group of languages spoken in Japan and some nearby islands. There are two main types of Japonic languages: Japanese and Ryukyuan. Japanese is the most widely spoken language in Japan while Ryukyuan is spoken by people who live in Ryukyu islands.
Within Japanese, there are different dialects or ways of speaking the language. These are classified into three main groups based on where they are spoken: Eastern Japan, Western Japan, and Kyushu. Eastern Japanese includes the standard Tokyo dialect which is commonly used in formal settings like business or education. Western Japanese includes languages spoken in Kyoto and Osaka which are known for having a different accent and intonation compared to Eastern Japanese. Finally, Kyushu dialects are spoken in the southern island of Kyushu and have significant differences in vocabulary and pronunciation compared to other Japanese dialects.

For example, Okinawan is the most widely spoken Ryukyuan dialect and has words that are similar to Japanese while Yaeyama has more similarities to the languages spoken in the Philippines or China.
