# Summertime (Cinnamons and Evening Cinema song)

"Summertime" (stylized in lowercase) is a song by Japanese bands Cinnamons and Evening Cinema, released digitally on August 7, 2017. The song was composed and written by Natsuki Harada, the vocalist, keyboardist, and guitarist of Evening Cinema.
In 2019, "Summertime" went viral in Southeast Asia, and its popularity spread to Japan through TikTok. In 2021, the song was adapted into a novel titled Kimi no Toriko ni Natte Shimaeba, Kitto.

## Background and release

"Summertime" is described as a love song. The composition and lyrics to "Summertime" were written by Natsuki Harada, the vocalist, keyboardist, and guitarist of the Japanese band Evening Cinema. Harada stated that, while composing "Summertime", he did not know how to compose music. He drew influences from J-pop songs from the 1980s, and while he did not intend to make "Summertime" a city pop song, the song became associated with the city pop revival in the late 2010s due to its association with the 1980s.
Evening Cinema collaborated with Japanese band Cinnamons, with vocals performed by Harada and Mariko Suzuki from Cinnamons. In 2022, Harada stated that, at that point, Evening Cinema had been doing live performances with Cinnamons often, and the idea for collaboration had spontaneously occurred at an after-party after one of their joint live shows.
"Summertime" was released digitally on August 7, 2017, on an independent label. It was later released physically on CD as a double A-side single with the song "Tokimeki of Winter" on December 12, 2018. A version of "Summertime" (サマータイム, titled in katakana) with a new arrangement was released on Evening Cinema's 2018 studio album Confession. In 2017, "Summertime" was featured in a commercial for the chat novel mobile app DMM Teller.

## Music video

The music video for "Summertime" was animated by Tsukunem (credited as Tsukunejirou), who also provided the illustrations to the single's cover. The animation features a man and a woman on a drive by the coast who are cast under a love spell.

## Cultural impact

"Summertime" received little interest during its initial release in 2017. "Summertime" went viral in Southeast Asia between the end of 2019 and the beginning of 2020, where it ranked no. 1 and no. 2 on the Spotify Virtual Charts in Vietnam and the Philippines respectively. In 2020, the song went viral on TikTok, inspiring song and dance covers. It became known under the hashtag "#KimiNoToriko", or "#KimiNoTorikoNi" (#君の虜に, lit. "Only if I could just fall for you") in Japanese, from the song's opening lyrics. By July 2020, it was the most used song on TikTok in Indonesia, Singapore, the Philippines, and Myanmar. The popularity of "Summertime" in on TikTok led to the song gaining more traction in Japan. Despite Harada's lack of intent to make "Summertime" a city pop song, he attributed its popularity to the city pop revival in the late 2010s, as well as the music video being animated.
By the end of 2020, "Summertime" ranked no. 7 on Spotify's Most Played Songs by Japanese Artists Overseas. The song won the TikTok Buzzwords Award 2020 in the music category for the hashtag "#KimiNoTorikoNi". In 2023, "Summertime" was nominated in the category for Top Streaming Music of the Decade at the Independent Artist Awards by TuneCore.
