How would YOU research products, made in the USA, for exporting?

Hey everyone. I am working on a project in my spare time for someone I work with. It's going along well so far, but a little help would be appreciated. What I need to do is find products made in the USA in the following categories: robotics, health care (digital health), environment, and energy/recycle. The companies who make these products must have their own research and development departments. The intention of this is to introduce these USA products overseas in Japan through a very well established network of marketing, sales, and distribution departments that I have been recently fortunate enough to have access to. As of now, I have been scanning the following sites for the past few days for product discovery/research: Pinterest and Kickstarter.

I have the following questions:

Anyone know of any more place to go or ways to research online?

A Google alert search perhaps?

Anyone know of any products, perhaps even your own, that you think would do well in Japan?

If you can offer any feedback, it would be appreciated. This is kind of an open question that may lead to some alternative interesting discussion.

Thank you!
