Well the article we're commenting on claims it's also an East vs West thing, and that Asians are "deeply in guess culture". Which, if you know Mainland China only a little you'll know isn't a thing, because in China it's not uncommon for people to make the most outrageous requests without breaking a sweat. Which in turn is seen as embarrassing or rude by some other Chinese. That may be much less common in Japan, where people are obsessed with etiquette. But then the author should say it's a part of Japanese culture, not Asian culture.
All this seems like good old stereotyping to me. It often comes down to the individual family or even the individual person. Maybe their social skills, maybe their level of selfishness. Maybe also how much they care about how they're seen by others vs how comfortable they are being themselves. A lot of factors can play into this.
