The only non-wacky non-historical documentaries I've seen in English were all pretty old pre-boom kinda stuff, or about discrimination. Probably also not good to show the rents. No one is going to make a modern documentary about anything other than Akiba type crap, since that is what people want to see.
In my case, my father thinks that Japan is like the ghetto red-light/entertainment areas he saw in Thailand/Philippines when he was in the military, since that is all he has seen of Asia. I never sought his permission/approval/help to go though... You've gotta start living your own life at some point.
iirc you're the one with the religious fanatic parents?

You can probably never conquer their racial/religious hatred/suspicious/spite for others, but if it's more about your safety overseas here are some bulletpoints:
-Japan has the second largest economy in the world
-Japan has a higher standard of living than America
-Japan has manatory national healthcare, even for foreigners
-Japan is one of if not the safest country in the world (re: violent crime)
-Japan has the highest life expectancy in the world
-One can get by just fine not speaking ANY Japanese
-It's not actually that expensive if you adjust your lifestyle
-Food here is much healthier than in the US due to less use of preservatives, chemicals, additives, etc. Most western food is easily available if you want it, but you probably like Japanese food too anyways.
-It isn't a car based society so chances of dying in an accident are much lower than in the US (dying in a crash is #1 cause of death in the US iirc)
-While there is some discrimination, it is based on xenophobia and not racism (at least if you're a westerner) and so isn't directed personally at individuals as much (you aren't going to get lynched but it might be harder getting the apartment you want). Personally I experienced MUCH more xenophobia (of the hate variety) as a white Canadian in Texas than as a white Canadian in Japan.
