Japanese manufacturers tend to horizontally integrate their businesses across a wide array of product lines. Take Yamaha, for example, which makes everything from motorcycles to acoustic grand pianos. Or Honda, which – in addition to cars and trucks – makes motorcycles, marine engines, anthropomorphic robots, and even jet aircraft. And it produces a wide array of power equipment. Like power generators, snow blowers, and lawn mowers. And not just in Japan, either: As of just a few years ago, Honda had sold over 40 million power-equipment products in the U.S. since it started offering them here in 1973. That's nearly twice as many as all the Civics it has sold around the world. And with over 24 million sold, that's Honda's top-selling automotive nameplate.
