James Yoshinobu Iha (Japanese: 井葉吉伸, Iha Yoshinobu or ジェームス・イハ, Jēmusu Iha) born March 26, 1968 in Chicago, Illinois, U.S.) is an American rock musician. He is most famous as having been a guitarist in the alternative rock band The Smashing Pumpkins and for his eclectic musical projects of recent years, including A Perfect Circle. He is currently a member of the band Tinted Windows with members of Cheap Trick, Fountains of Wayne and Hanson.
Iha attended Elk Grove High School in Elk Grove Village, Illinois, which he described as "a boring, middle class suburb of Chicago." Iha received average grades in high school, and, after a successful two-year stint at a local junior college, he majored in graphic design at Loyola University Chicago before dropping out to dedicate himself to the Smashing Pumpkins. He currently lives in Manhattan, New York and co-owns independent record label Scratchie Records with Adam Schlesinger of Fountains of Wayne. Bands on the Scratchie label include The Sounds, Albert Hammond Jr., and Office. He also co-owns a recording studio with Adam Schlesinger and Andy Chase of Ivy called Stratosphere Sound in Manhattan.
He is a second-generation Japanese-American, and is only able to speak a little Japanese. Like his former bandmate Billy Corgan, he also has a brother with a disability.
