Murakami also has a passion for listening to music, especially classical and jazz. When he was around 15, he began to develop an interest in jazz after attending an Art Blakey and the Jazz Messengers concert in Kobe. He later opened the Peter Cat, a coffeehouse and jazz bar. Murakami has said that music, like writing, is a mental journey. At one time he aspired to be a musician, but because he could not play instruments well he decided to become a writer instead.
