Japanese is a language spoken by over 130 million people in Japan and in Japanese emigrant communities. And it is written with a combination of three scripts Chinese characters called kanji, and tow syllabic scripts made of modified Chinese characters, hiragana and katakana. The latin alphabet, romaji is also often used in modern japanese, especially for company names and logos, advertising, and when entering japanese text into a computer.
I will talk about japanese language origin. The classification of the Japonic languages is unclear. The group is traditionally considered to consist of a single language. There are so many theory has researched by scholar.
The first one is Koguryoic hypothesis. Koguryo was one of the mikuni aspirations in chinese history. Gogureo some numerals were very similar to japanese. next one is korean hypothesis. It is insisted that japanese relation to korean because their grammar of how to use is similar.
other hypothesis, Altaic and austronesia is also existed. There are many theory is insisted, but Japanese origin is not clear, many researcher still continue their investigation.
