Doing Business in Japan

Been trying to get some business contacts set up in Japan to accomplish a few target goals..

1. Get wholesale sourcing on videos for resale in the US market
2. Find and contract photographers to do gay japanese photo shoots
3. Find and contract videographers to do gay japanese video shoots

We have contacted several porn companies in Japan, via email, letter, letters written in Japanese, direct contact through emissaries going to Japan..
all with no luck.

Anyone with any suggestions on how to tap into this market to accomplish the 3 stated goals above ?

Asian people as a whole are very skeptical when it comes to new business relationships but we have been trying for several years without progress...

Perhaps I am missing something?

Perhaps someone on the board has some referrals or suggestions?

Thanks

Tom
