No where did I say that you are a liar or that I know more about Japan, you are clearly making that up or just being overly precious.
I wrote a long response to this but have deleted. The running personal attacks/defense/justification/counterattacks are not productive. Let's just call it a day, shall we?
So you are saying that the sites, the people who run the sites are liars and they run a 2 tier market in Japan?
I never said that. As I have said throughout the properties they are selling are not representative. They do not fall into the category of an "average dwelling".
Expats have different requirements and different standards. Accordingly the apartments that are being shown are of a different class altogether.
Your characterization of Japanese apartments as "dogboxes" is representative of this. Most Aussie/American families would probably be horrified if they were put into an "average" tokyo family's apartment. They are not used to living that way and they don't know how to do it. For Japanese people it can be a little cramped, but in Tokyo everything is cramped. You get used to it.
The places with the multi million dollar price tags listed on your sites are palacial by Japanese standards, with some going as high as 180m2. What is more, you only really get big apartments (120m2+) in fancy luxury buildings that are centrally located (i.e. 2-3 minute walk to major station), surrounded by fashionable shops and usually providing a range of on-site services such as concierge, etc. Think upper east side, manhattan. So it's not simply a question of m2.
Consider the reverse situation. A Japanese-language real estate agency based in Sydney targetting expat Japanese businessmen (i.e., elite and wealthy) coming to Australia but not having much/any competency in the English language or knowledge of local customs/laws. That is what the sites you listed are, but in reverse. The kinds of properties they list are marketed to that sort of clientele.
Perhaps I was careless in characterizing them as "overpriced". From the perspective of an average Japanese (or an expat who is wholly familiar with the language and the customs) they are certainly overpriced. For someone who does not have that background, the extra cost might well be worth the extra security of being able to deal with a brand you know and trust in a language that you can understand with people who are familiar with the situations of expats.
But hey, you are the expert, you are clearly right and those sites I linked to are there just to sucker in the Japanese speaking reading expats, but, couldn't those same Japanese speaking reading expats then read the sites you liked to?
If these expats could read/write/speak and understand Japanese and had the time to do the research I am certain that they could find a better value for their dollar even if they were buying the same level of prestige properties. However most cannot. Most have little or no knowledge of the language. so they rely on places like Century 21 which offers premium services for such customers and, as a result, charges premium prices. It's the same the world over.
Wouldn't they see that the sites I linked to were according to you BS? How would Century21 etc even stay in business?
Not BS, or at least not completely BS. But certainly not representative. Since this thread was, way back when, talking about "average dwellings" it is important that the samples used be representative in order for them to have any meaning.
This particular Cent. 21 branch (cent. 21 is not a major RE agency in Japan, btw. I have only ever seen it advertised in media targetting foreigners in Japan (such as english language cnn, etc.). I have never seen it advertised directly to Japanese) markets a very narrowly defined portfolio of properties to a very narrowly defined target audience. Their ability to stay in business is testimony to their skills in that very narrow field.
