In this concept album, Happy End attempted to paint a musical picture of Tokyo before the 1964 Summer Olympics, through which sweeping changes transformed the city forever.

[1] Takashi Matsumoto's lyrics to "Kaze wo Atsumete" were inspired by a line from a poem by Fuyue Anzai that he saw scribbled in the bathroom of Max Road, a Shibuya café that he frequented.

The song's title is a pun: "aiueo" is the order of pronunciation in Japanese, while ai ue (愛飢え) translates as "love hunger".

[6] The front cover of Kazemachi Roman features portraits of the four members of Happy End drawn by manga artist Kazuhiko Miyaya, whom Matsumoto was a fan of.

[7] In actuality, while looking through photos Miyaya took as reference, Matsumoto was struck by an image of a trolley going down an S-curved hill on the Toden Arakawa Line in the Ōji area of Kita.

Although Matsumoto had a vague connection to the area through his aunt, the other members of the band did not, so he requested Miyaya draw the trolley as if it were traveling from Shibuya, where Happy End was based, to Shinbashi.

[8] Together with their self-titled debut album, Happy End's Kazemachi Roman marked an important turning point in Japanese music history, as it sparked what would be known as the "Japanese-language rock controversy" (日本語ロック論争, Nihongo Rokku Ronsō).

[11] AllMusic's Jesse Jarnow described "Sorairo no Crayon" and "Kaze wo Atsumete" as "decent country rockers" that could stand with any contemporary "west coast psych-twang LP" and "Hanaichimone" as one of the album's "slick and sleek organ-driven pop tunes".

Calling it "California folk-rock filtered through Tokyo, streamlined and, well, perfected", he also noted the sweet melancholic and nostalgic songs with their "aching, vulnerable harmonies.

"[12] In September 2007, Rolling Stone Japan ranked Kazemachi Roman No.1 on its list of the "100 Greatest Japanese Rock Albums of All Time".

[18] "Kaze wo Atsumete" was covered by Mayu, Manaka and Asahi from Little Glee Monster for the 2021 Takashi Matsumoto tribute album Take Me to Kazemachi!.
