Dressing code

I have a business trip to Japan to a high tech company. I was wondering what is the dressing code for women in such companies.

I don't know in what position you are going, and whether you are holding business meetings (contract negotiation, etc.) or getting to work in their work places, or receiving any training, but still the comments here might come in handy as general statements:

Also, when you say ''high tech,'' do you mean software development/programming kind of, or computer and other hardware manufacturer type of company? If it's software development, then people tend to dress very casually (including jeans) . But as a visitor, I would still recommend being on the conversative side

My father is a high tech executive and he strongly recommend - for a initial meeting you dress conservatively since executive are judged on merits.

Thanks.
Some more information: I work is a software company that develops software product to a very big and successful Japanese company that does both software and hardware. I work in the development side and my trip is to close the details regarding the software. what do you think?

If you are not sure, it is always best to be over-dressed than under-dressed!
