Upon its release, "Go! Go! Let's Go!" received positive reviews from music critics, who commended the tracks mixture of genres and production, with compliments aimed towards their incorporation of the Japanese Neo Girls concept.

Commercially, it experienced minor success in Japan, peaking at number two on the Oricon Singles Chart and on the Japan Hot 100, the latter published by Billboard, but selling fewer copies than their previous releases. In order to promote the single, E-girls performed in the accompanying music video, which was directed by Daisuke Ninomaya, and features the band exemplifying the respective concept into the visual; for example, the girls utilize various Japanese cultures. Additionally, the girls sung and performed the track on several shows.

Background and composition
After releasing their "summer concept" singles "E.G. Summer Rider" (July 2016) and "Pink Champagne" (August 2016), E-girls continued recording material for their fourth studio album, E.G. Crazy (2017). On October 20 that year, the band announced through their website about the release of "Go! Go! Let's Go!", and confirmed its pre-order availability that same day. Details were still unavailable at the time, but revealed the three accommodating formats for the single. Additionally, this is the last single to feature Dream member Erie Abe, whom announced her retirement in October from both E-girls and Dream, and the entertainment industry as a whole, by the end of the year; on December 31, Abe committed to her promise and left the bands.

The song was written by Kotake Masato, composed by Lisa Desmond, Erik Lidbom and Maria Marcus, and produced by Exile's Hiro. Musically, it is a dance number that incorporates elements of hip-hop and rock music, and delves into themes of being ambitious and moving on. According to a contributing editor of CD Journal, they felt that the single presented an "edg[ier]" dance sound, and also noted elements of Westernized contemporary R&B music. Similarly, a staff editor from Tokyo Girl Update believed the track "mashed hip-hop and rock" sounds together, and managed to keep within the concept of E.G. Cool, a recurring theme from E.G. Crazy. "Go! Go! Let's Go!" is the third single after "E.G. Summer Rider" and "Pink Champagne" to include vocals from all remaining vocalists from E-girls; these are members Shizuka, Aya and Ami from Dream, Karen Fuiji and Ruri Kawamoto from Happiness, Reina Washio from Flower, and original E-girls member Yuzuna Takebe. Accompanying the single is the B-side "Bon Voyage", which is included on the physical and digital distributions. Composed as soft tropical house–pop number, it features vocals from all singing members.

Release
"Go! Go! Let's Go!" was taken as the final single from their fourth studio record E.G. Crazy (2017) where it featured as the closer to the E.G. Cool disc. The track was released on November 30, 2016 through Rhythm Zone and Avex Music Creative Inc. in three physical formats—two CD's and a DVD bundle—and for digital consumption. The standard CD release, and DVD bundle included both songs; the former formats featured its instrumental compositions, while the DVD only placed the single's instrumental as track number three, and a bonus disc featured the music video. A special One-Coin edition was made available on their website with limited pressings, only including the single and a promotional trading card that ranged from 20 different kinds. Furthermore, a flyer was placed inside the jewelcase that gave access to exclusive merchandise that was available on the band's website. The single was made for digital consumption that same day, but included the first two tracks. The cover art featured all members except Erie Abe; the separate CD and One-Coin editions featured each member placed randomly in front of the song's text, while the DVD package feature all members standing and sitting next to the song's title. Japanese retail store CDJapan had issued first-press editions that included a trading card and sticker for each format, and a limited edition photo album that included each member, including Abe, in their looks from the video, for the DVD packaging. The CD only version featured an A3-size poster of the DVD cover.

Reception
Upon its release, "Go! Go! Let's Go!" received positive reviews from music critics. A contributing editor of CD Journal was positive in their review, commending its mixture of sounds and instrumentation. The review also noted its arrangement and R&B elements, and described it a "new standard" for Japanese music. In an article written from Tokyo Girls Update, a staff member agreed about its choices of genres, but also believed its lyrical content of moving forward "takes on another meaning" since member Erie Abe's retirement announcement. Despite enjoying the track and its B-side "Bon Voyage", Sou of Arama Japan felt the packaging and concept was "unoriginal". Reporting from Musicman-Net, an editor felt it fit the entire E.G. Cool concept, and compared it to the E-girls' single "Pink Champagne".

Commercially, "Go! Go! Let's Go!" experienced minor success in Japan. It opened at number two on the daily Oricon Singles Chart, continuing their streaks of top three positions, but remained unsteady for the remaining six days.

On the week of its availability, the single re-entered the chart and opened inside the top ten at number five, its final peak position, but started to descend quickly. Additionally, "Go! Go! Let's Go!" reached number 16 on the Radio Songs chart and number two on the Hot Single Sales chart, and garnered a similar run to the Japan Hot 100 chart.
