When you come home (back) ... people say 「おかえりなさい」(Okaerinasai).
Okaerinasai (おかえりなさい) is a Japanese greeting on returning home.
帰る(Kaeru) means returning home.
The same "Kaeru" also mean カエル(flog). At 伊勢 (Ise) there are many flog figures near the beach. This is to hope people to come home safely from the fishing.
Since 1996, Japanese-Online has been provided as a free service from PSPinc with the purpose of providing resources to individuals interested in learning about the Japanese Language and culture.
Japanese-Online has content suited to varying levels of study, including lessons for beginners as well as lessons tailored for those who need grammar and writing resources. Lessons are best suited to those who have basic understanding of hiragana and katakana alphabets before moving on to the more advanced grammar and particle lessons. Grammar lessons focus on learning about writing and creating more complex sentences and most lessons will not use romaji (Japanese sounds written with roman letters). Kanji is used in the lessons with hiragana and English translations provided.
