ga Kitara" (Hyper Bug Mix) and "Ashita, Haru ga Kitara" (Techno Dub Mix) was released on August 21, 1997, through BMG Victor. It also features a remix of the album track "Love Sick", titled "Love Sick (Deep Sick Mix)". Reception A reviewer for CD Journal commended "Ashita, Haru ga Kitara" for being "pure" and noted that Matsu's "unobtrusive [and] naked voice" is like "sitting in a sunny spot on early spring day". Similarly, Rolling Stone Japan wrote that the song has a "heartwarming" production, which they noted has become synonymous with Takako Matsu. Another reviewer for CD Journal said that the b-side, "Zutto... Iyō yo"s arrangement makes it an "impressive pop song". Since its release, "Ashita, Haru ga Kitara" has often been associated with the onset of spring in Japan. The song also entered the top requests list of many FM radio stations around the same time. Since the introduction of Billboard Japan in 2010, the song has spiked on its airplay charts during the time of spring. It was also included on the compilation True Love: Spring Memorial Songs in 2003. In a web poll conducted in 2013 by MyNavi news asking people about their favorite spring song, "Ashita, Haru ga Kitara" was ranked at number 10. The single debuted at number 15 on the Oricon singles chart during the week following its release in March 1997, selling 35,640 copies. A few weeks later, it moved to number 8, moving 46,400 copies, which became its peak position. The single spent nine weeks in the top 20, including two in the top 10, and finished at number 75 on the yearly chart, due to sales of 428,170 copies. As of May 2014, it has sold 431,540 copies in Japan and has been certified platinum by the Recording Industry Association of Japan for shipments of over 400,000 copies. Live performances and covers In 1997, Matsu performed the song at the 48th Kōhaku Uta Gassen in 1997, representing the "Red" team in the event. The previous year, before her debut as a singer, she had hosted the "Red" team. This made Matsu, who was 19 at that time, the youngest person to reach that position in the event. In June of the same year, she appeared on the show Love Love Aishiteru, her first music talk show appearance, and performed the song along with a cover of Seiko Matsuda's "Hitomi wa Diamond"
