If you put together any video footage along with a resume and an analysis of your abilities (it might be a good idea to ask your coaches to write you something), I would like to see it so that, if I like what I see, I can pass it along to some people who could really help you.
In any event, even if you can't find a way to a pro team, you should continue playing baseball just for the joy of it. Good luck.
However, many players have agents who don't have that experience. So, how do they get it?
Well, a self-motivated agent would probably check the FAQ and find the team contacts page, and phone, fax, or snail-mail the various ball clubs. I think that such an agent would have a better chance of getting a reply if (s)he corresponds in Japanese - especially at the start. That would probably entail hiring a Japanese exchange student from a nearby university so as not to insult teams with first contact. (Please keep in mind that you're getting this advice from a fan who knows nothing about business. In other words, adopt this advice to what you know of the practices in your trade.)
I've got a question for anyone who's familiar with how agents work. With computer programming, there's the Open Source movement whereby programmers help out other programmers, even the competition, for the betterment of the community. In fandom there is SABR, Baseball Guru, this site, and many others where fans help each other through publishings, studies, and discussions. Do agents have any kind of community to help one-another get the information necessary to do their job better, or in this case, to learn how to do business with Japanese teams? Or is it all cut-throat, dog-eat-dog?
This is a site about Pro Yakyu (Japanese Baseball), not about who the next player to go over to MLB is. It's a community of Pro Yakyu fans who have come together to share their knowledge and opinions with the world. It's a place to follow teams and individuals playing baseball in Japan (and Asia), and to learn about Japanese (and Asian) culture through baseball.
It is my sincere hope that once you learn a bit about what we're about here that you will join the community of contributors.
