I'm going to take you seriously, and guess that you're not in Japan now. If you are living in Japan stably, and you work hard, you could be taken on by an agency and work your way up from there, but it can't be your primary option. You could incorporate this acting idea into your future if you have another legitimate reason to be in Japan, so decide on that first.
You can get over there for a short time through college or a language school, but it's illegal for you to work in the entertainment industry on a student visa. An agency that would employ you in that circumstance is probably very dodgy.
In the meantime, are you happy with building up an acting resume in your own country? Apply to any small acting or modelling jobs near you now, advertisements being a good example.
Of course they "pick people who are best looking". If you grew up outside of Japan, your idea of good looking may be a little different from what's sought over there.
Improve your Japanese. You need to be able to speak for yourself. No matter how well you think you speak and read, you also need a Japanese citizen you can trust, who can read anything and act as your contact. Having a savvy relative there would be invaluable to you. Actually, this goes for moving there, acting aside.
Finally, you need to be realistic about the acting and modelling industries in both your home country and Japan. It's very easy to get taken advantage of and slip into the adult industry, or get into real financial trouble, even more so if you're foreign. Even if you've always felt drawn towards acting, it needs to be your secondary option.
