Gomen nasai, Kuifje-san, Nihon ga go hansae-masen.
Oh man, I can't even read it in Japanese. The kanji and hirgana characters I haven't even learned yet .
A guy that I know personally myself, has been studying Japanese for over 10 years since he got out of the Navy. I have to admire his tenacity at mastering Japanese including the kanji and hirgana character writing system. Bet he will feel at home with the Japanese AD.
Bai bai & Ja mata! (good bye- informal and semi-formal)
Senshi...(solider) Sensi...(teacher) kawaii usagi! (cute bunny!)
...
hm.
I used to know a lot of japanese words but now apparently it have evaded from my mind.
