“What’s important is that the people that I work with are also recognized and that it’s the Nintendo brand that goes forward and continues to become strong and popular,” he said by way of comparing Walt Disney’s role in the larger brand with his. “And if people are going to consider the Nintendo brand as being on the same level as the Disney brand, that’s very flattering and makes me happy to hear,” he added, through an interpreter. (He understands spoken English well but does not speak it beyond a few phrases, a twist of considerable amusement to him given that his father taught English.)

Mario, the mustached Italian plumber he created almost 30 years ago, has become by some measures the planet’s most recognized fictional character, rivaled only by Mickey Mouse. As the creator of the Donkey Kong, Mario and Zelda series (which have collectively sold more than 350 million copies) and the person who ultimately oversees every Nintendo game, Mr. Miyamoto may be personally responsible for the consumption of more billions of hours of human time than anyone around. In the Time 100 online poll conducted this spring, Mr. Miyamoto was voted the most influential person in the world.

But it isn’t just traditional gamers who are flocking to Mr. Miyamoto’s latest creation, the Wii. Eighteen months ago, just when video games were in danger of disappearing into the niche world of fetishists, Mr. Miyamoto and Satoru Iwata, Nintendo’s chief executive, practically reinvented the industry. (Mr. Miyamoto’s full title is senior managing director and general manager of Nintendo’s entertainment analysis and development division.) Their idea was revolutionary in its simplicity: rather than create a new generation of games that would titillate hard-core players, they developed the Wii as an easy-to-use, inexpensive diversion for families (with a particular appeal to women, an audience generally immune to the pull of traditional video games). So far the Wii has sold more than 25 million units, besting the competition from Sony and Microsoft.

In an effort to build on this success, last week Nintendo released its new Wii Fit system in North America, a device that hopes to make doing yoga in front of a television screen almost as much fun as driving, throwing, jumping or shooting in a traditional game. Though there were no hard sales figures available as of Tuesday, there were reports of stores across the country selling out of Wii Fit.
