Lately I'm into this Nintendo DS (NDS) game by the name of "Japanese Coach".
I would recommend this game to those who are interested in learning Japanese language.
It's a fun, cheap and handy way of learning Japanese Language.
In this game, it covers all Japanese writings which is Hiragana, Katakana, Romaji and even Kanji.
Not only that but also every level includes a little piece of info about places or some informative things that you would like to know about Japan.
You can even read out loud to record your voice as referrence just to see whether it sounds right or maybe to sound like a native speaker.
Besides, what I love about this game is that it has a dictionary and also it helps to improve my kanji writings.
Get a hand on this game if you have a NDS.
