Where did factories start and where/how did the factory system spread?

The Industrial Revolution brought on factories that started in Britain mainly because it had the iron deposits, and the coal to power many machines. Factories spread because of outside sources bringing the idea during trade and the fact that nations, such as China and Japan, looked to the West and saw the success and had the drive to start factories for economic growth. Factories later to places such as China and India, but had worldwide recognition. China was not the first to use factories to mass produce goods such as porcelain and silk and did not lead in industry, but had the biggest economy along with India until about 1900, when Britain ultimately surpassed them in overall production. Factories spread greatly through connection with other regions. This can be expressed when the Japanese were finally opening ports to Europeans after Matthew Perry eventually opened the ports in 1854 for Europeans. Along with the goods now entering the Japanese, there were also new ideas, one of these ideas was the factory system. By the 1870s the Meiji Restoration saw the making of thousands of miles of railroad and telegraph lines, and by the early 20th century the country had around 32,000 factories.
