Nintendo Integrated Research & Development Division, commonly abbreviated as Nintendo IRD, was a Japanese developments division that handled everything related to producing Nintendo's console hardware and associated peripherals. Originally established in the 1970s with engineer Genyo Takeda acting as manager, Nintendo Research & Development No. 3 Department and part of the Manufacturing Division, the department was responsible for various hardware technologies and even developed several arcade and console titles. In 2000, as technology evolved into the 3D era, Takeda's group spun-off and established itself as a division into Integrated Research & Development Division, and began spending longer periods of time researching and testing the various and rapidly evolving hardware that would power Nintendo's next generation of consoles.
