What we found is that the literal translation of "I just got home" in Japanese is "Ie ni tsuita bakari" (家 に ついた ばかり).
Much about the roots of the Japanese language is unclear. Some link it to the Altaic language family, which includes Turkish, Mongolian and other languages, but it also shows similarities to Austronesian languages like Polynesian.
In comparison with other languages, Japanese knows relatively few sounds, and pronunciation poses little problems to most learners. The biggest difficulty are accents, which do exist, but to a much lower extent than in the Chinese language. In addition, there are relatively many homonyms, i.e. words that are pronounced the same way, but have different meanings.
