Houkai Amplifier is the major-label debut EP by Japanese rock band ASIAN KUNG-FU GENERATION, released on November 25, 2002 on Under Flower Records.
After six years since its inception and three independent releases, Asian Kung-Fu Generation contributed to the Under Flower compilation album, Whatch You Gonna Do?, before dropping their first major-label EP. The critically-acclaimed mini-album topped the High Line Records weekly chart for two weeks straight and peaked at number thirty-five on the Oricon indies sales chart. Due to its success, H?kai Amplifier was re-released by Ki/oon Records on April 23, 2003. Although the mini-album didn't release any singles, the intro track "Haruka Kanata" enjoyed immense domestic and international popularity after it came to be used as the second opening theme for the anime series Naruto.
