About Application to Japan Universities

Hi there, I'm a high school student who lives in Turkey, Istanbul. And this year, I became 11th grade student. So I plan to study in a good Japan University (especially for agriculture) after 2 years have passed. Frankly, I got nervous about application to Japan universities, because I don't know which part I need to start. Like which exams I need to sit for? And where or whom I need to submit the exams results? Can I need N1 or something? Or just English is enough? Actually, my english is not that great, in my opinion it is around b1 – b2 for now but I believe that I can improve it in 1 – 2 years. Any slightest advice or info would be great. Thanks for in advance.
