Health Care in Tokyo, Japan

I have a 15 years experience in Japan, having different small or bigger medical problem (2-3 time a year), but except some "stupid experiences", I have nothing bad to say, only nice words.
My "family doctor" retired 2 years ago, at a 94 years old age. He was an excellent doctor, he was taking care about me including on his free time. He gave me his "private" phone number to call in the case of an emergency. I was the youngest patient of this doctor (I am almost 50 years old). He "made" me well after heavy burn on my face, after being poisoned by a dangerous local spider or by "futsu mosquito" (I have no natural anti-toxine in my blood, like local people have) or other "small-big problems", small for others but big for me.
Another place I was sometimes visiting was a hospital, for specialized check-up... a perfect place, the most new medical devices, also the best trained doctors. (and providing also english language).
Another hospital I visited was also "specialised" and I have only good words to say about the medical care I get here.
Bad experiences - only twice -
1. once at an emergency room in an isolated area, but a big hospital - after falling down 2 m into a concrete river bed - I was waiting a doctor almost 1 hour and after an x-ray another one hour to hear that I am well, nothing broken - that fact I told to the staff at entering the emergency room (walking on my legs), I was asking only for cleaning and stopping the blood to flow out... (blood stopped alone in that 2 hours anyway, but cleaning was not done, so I get infected very bad)
2. when I was once waiting for 6 hours at the door of the doctor, from 9 00 Am ( 9 30 was the appointment time). I really did not understand what was the problem, and I get so angry and told them how stupid they are. (in exchange for my waiting time, I get a "big discount" at the cashier)
