Nintendo certainly needs a hit.
Net profits slumped by 74% to 49.5bn yen ($598m; £372m) in the nine months to December on the back of falling sales and the strong yen.
The company faces tough competition from Sony and Microsoft, and new entrants to the games market like Apple’s iPod and iPhone and other smartphones.
Games like the hugely successful Angry Birds are a fraction of the price of Nintendo’s titles.
“Nintendo makes software for our own hardware,” says Mr Miyamoto.
“Of course I try to make software that is valuable enough for customers to pay for it. So the fact that different types of games are available to customers, and what happens to Nintendo’s games seems a separate issue to me.
“So my goal is to continue creating the software to high standards. As long as we keep doing that, I believe our business will follow.”
An innovator he may be, but Mr Miyamoto is in some ways a typical Japanese salaryman.
He has worked for Nintendo since 1977, never creating a company in his own name, nor the vast fortune to go with it.
When asked why, he laughs.
“Maybe I am richer than you think,” he says.
“But seriously, it is not me, myself, creating any software at all. I am working comfortably with a bunch of other colleagues and that is how I like my job.”
