Before we jump all over the poster, let`s give a little more time to explain.
Right now, the explanations are not very convincing, however.
Saying that you are Japanese when you are not is not an uncommon thing at all. In the looking for friends area, I am willing to bet that quite a few of the users who say they are Japanese are not so. Users respond to "Japanese" like it`s the most favorable trait out there, without ever doubting. For those who do speak Japanese here, however, it`s usually quite obvious by looking at the Japanese usage...
If the original poster truly is Japanese but living in France, then there is no problem. However, I am very wary to believe someone who says they are Japanese living in France since 3 - but yet cannot speak Japanese and who says their first language is English.
