I`ve read this online many times already. That Nintendo only cares about Japanese sales and if they have to do something in detrimental of the rest of the world  to save their japanese sales they will do it no caring about revenue and profits because Japan is what matters to them.

There`s any interview or statement where any Nintendo important person directly said that? Because it`s very illogical considering Nintendo is and open traded company, and even if it wasn`t, it`s a company, and they want to make profits, where they come from should not matter.

There profit margins are obscene, always backfires. I wouldn't be surprised if Nintendo provided more support in Japan after the switch struggles in the west of the world.

Just an opinion that more people are thinking to be true

Nintendo definitely cares about rest of world since a huge portion of their profits come from there

A person or company can be interested in their own heritage more than others and still very much care about them all.

But Nintendo always want to be as universal as possible, considering nationality, gender and age. They want to make games for everybody, wherever a 10 years old boy from New York, a 25 year old woman from London and a 40 years old man from Tokyo, can play and have a good time. This seems to me that it`s much more their focus being universal than pleasing japanese only.
