Thanking in advance

[tanuki]

Hello!

I think this rather a cultural question than a linguistical one.

Do Japanese thank in advance? For example, in letters or in forum posts.

I have heard that it is rather presumptious in Japan, because one is assuming that the person will respond, is that right?

And, last but not least, if I really want to thank in advance, what would I write in Japanese?

Thanks in advance for your replies!

It's not an exact translation, but よろしくお願いします can be used in a similar fashion.

Well, you don't really have to specify that it's in advance, even in English.

"Hello, I have a question about [grammr topic here]. Could anyone please help me? Thanks."

It's exactly the same in Japanese. Just make your request, and end it with a ありがとうございます.
