My Japanese Coach (US)
For serious students of Japanese - this is just a nice and enjoyable game to learn some words
in japanese. for beginners, dont take it too seriously this game wont make you speak and understand japanese, it will just learn you lots of words and sentences. Indeed very useful is the feature of hearing the words in japanese, and you can write down & learn hiragana, katakana.
Good practice ! For real learning success watch Lets learn japanese & Nihongo Dekimasu TV Courses and read Minna no nihongo !
