"Japan has a culture based around personal networks and connections. Japanese consumers look for consensus and poll their friends in making a buying decision."
When door to door salesmen or telemarketers try to sell me things in Japan, they always start off with "Everyone in your area is doing XX" or "You're the only one in your area that isn't on XX yet."(1) It ticks me off to no end, but my wife (Japanese) actually starts reconsidering sales propositions when she hears that everyone else around her is doing the same thing.
As an American, I grew up with the phrase "If everyone else jumped off a bridge, would you?" instilled in me. Talking with my Japanese friends, they seem to find that saying very odd -- if everyone else is jumping off the bridge, there must be some merit to it, they try to reason.
(1) A network provider tried to convince me that I was the only house in the neighborhood who was not yet on the optical network. My neighbors are pretty much all over the age of 60, and many of them probably do not own a computer more powerful than a cellphone.
