He is just citing paragraphs from their law. Seems rather generic and doesnt really go into much detail.
Basically, if you went to medical school that is deemed equiavalent to the japanese medical education, you can take their Exam.

Of course, if that is that simple in reality might be another matter.

I would think long and hard about if you really want to do this.

That second link contains translations of their medical practitioner act. They dont seem machine translated.

Edit:

第十一条　医師国家試験は、左の各号の一に該当する者でなければ、これを受けることができない。

You might get better answers from people who actually went through it, rather than from official bodies like the one you wrote to. I suspect they don’t really care. They just copy-pasted the paragraphs and nothing more.

Ask around in expat forums like http://www.reddit.com/r/japanlife/

There is some info in the third link (the table at ３．書類審査の認定基準) but it’s only in Japanese. My understanding is still patchy so I only get the general gists (with the help of Rikaikun haha).

Im not quite sure whats the difference between the actual exam and the prelim exam.

Your med school has to be 6 year program, 4 of which is the (I think) clinical part. Or 5 in the case of prelem.
You must have graduated within the last 10 years, unless you kept practicing medicine. (something like that)
You must have graduated with good grades (vague..)
The teaching hospital, teaching staff have to be equivalent to a Japanese one. (again vague)
Your med school is registered in WHO’s World directory of medical schools.
If you havent received a medical licence in your home country you have to take the prelim exam (I thinik..)
You need to have JLPT N1 (this might take you a few years assuming you’re still a beginner haha)

Also before the actual exam you have an additional practical exam to demonstrate your Japanese skill.

Oh, not to discourage you or anything but..
Asian countries generally have this Senpai-Kouhai thing. Sticking out for graduates of the same University, rivalry towards other University even after graduation. Medicine being generally an even more conservative field than the country already is.
Breaking into that as a foreigner might be tough, on top of insane hours.
