hmm .. from europe without someone speeking and writing goood japanese, its hard, talking to japanese companies ... english won´t help you at all...

i had to work out cooperations in game-distribution with a japanese company this year, it was only possibel by taking my brother, who speaks japanese, with me ...

from here, it was not possibel, they don´t even answered to english letters ...

but maybe i can give you the address of a manga/anime fanatic living in japan (speaking german and japanese), i post again, if i can do something for you
