==Production==
Development for the show had begun during the summer of 2018.https://twitter.com/TomConstantines/status/1300248968320880640 Producer Takahito Omori had visited several technological institutes and spoke with many professors and experts on the topic of artificial intelligence. The suit's design was completed in time before the Reiwa-era change, but a name had not been decided on yet. Omori came up with the idea of "Rei-One", which was a shortening of "Reiwa's first Rider." It was later pointed out that "rei" could also be read as "zero", and that there was already a superhero named Kikaider with the "01" moniker. With the show being heavily-themed in technology, the name "Zero-One" was chosen as a reference to binary code and the trademark was filed on April 19, 2019.https://twitter.com/trademark_bot/status/1127954256294662144 
From this time until May, head writer Yuya Takahashi had completed the scripts for the first two episodes, while auditions for the cast were held. Filming began in mid-June 2019, and the cast were introduced through a scheduled press conference in July. The series premiered on September 1, 2019.
===Impacts due to COVID-19===
As a result of the ongoing COVID-19 pandemic, a state of emergency was declared in Japan on April 16, 2020https://www.bbc.com/news/world-asia-52313807, which delayed the broadcasting of new episodes following the airing of Superhero Time on May 10, 2020, which included Episode 35 of Zero-One and Episode 10 of . Ultimately, the release of Kamen Rider Zero-One: REAL×TIME which was originally scheduled to premiere that summer, was postponed until December in place of what would have been the premiere slot for the potential Movie War film between Zero-One and Kamen Rider Saber.
Further filming was temporarily ceased after the conclusion of Episode 39's production. Due to Toei wanting to maintain an early September airing for Kamen Rider Saber, Zero-One was given a final episode count of 45, which forced the production crew to make several script alterations to fit the reduced episode count.https://twitter.com/TomConstantines/status/1300248968320880640
*Several major plot-lines were scrapped, including an extended redemption arc for Gai Amatsu and ZAIA Enterprise's relationship with the original scripted version of Kamen Rider Ark-One.
*A Televi-Kun scan reveals that the initial identities of both Kamen Rider Ark-One and Kamen Rider Zero-Two were originally two different people, but the delays and reduced episode count resulted in the identities of both Riders being the same person instead. 
*Owing to long time Kamen Rider suit actor Seiji Takaiwa being casted as Horobi's suit actor, the long-term plan for the show's ending would be to have Horobi fight against Zero-One, but the process of how they would get there was undetermined at the time.
*There were various pitches for Ark-One's origins. One idea would've had Ark to assume a separate Humagear body to become Ark-Zero, evolving itself after learning more about humans.https://pbs.twimg.com/media/E0d0eAcVkAgiYhX?format=jpg&name=small Another pitch would've had Horobi's body possessed by the Ark to become Kamen Rider Ark-One.https://pbs.twimg.com/media/E0d0dxZUUAQ53o_?format=jpg&name=360x360
*Valkyrie was supposed to gain a power-up at the end of the story, but due to the reduced episode count, only Fuwa became Orthros Vulcan in order to stop Aruto.https://pbs.twimg.com/media/E0d0dhNUcAEgnO0?format=jpg&name=360x360
To allow time for the production team to rewrite scripts, a series of recap episodes were aired for five consecutive weeks from May 17, 2020, to June 14, 2020: the two-part "President Special", focusing on Aruto and Is, the "Shooting Special" focusing on Isamu and Yua, and the two-part "Super Work War" focusing on the Humagears throughout the series. At this time, Japan's government had lifted its state of emergency on May 25, 2020, allowing Toei to resume filming Zero-One and Kiramager under newly placed guidelines to control any further spreading of the COVID-19 virus.https://news.yahoo.co.jp/articles/98c01dea11eec97815ad98c53af95d52c74fa21a The series resumed broadcasting full-length episodes on June 28, 2020 starting with Episode 36.https://www.cinematoday.jp/news/N0116502 Filming wrapped up on August 4, 2020 and the finale aired on August 30, 2020.

==Notes==
*With "zero" in Japanese and "one" in Japanized-English, Zero-One can be read as in Japanese, referencing the fact that he is the Kamen Rider of the Reiwa era.
**The characters "zero" and "one" are known in tech, electronic and the mathematic world as , which is fitting for the series due to its theme of artificial intelligence.
*This series marks the first time since Hibiki where Seiji Takaiwa is not the suit actor of the Primary Rider. Instead, Takaiwa portrays Kamen Rider Horobi, while Yuya Nawata took on the titular role of Zero-One.http://tokusatsunetwork.com/2019/08/kamen-rider-zero-one-main-suit-actor-revealed/
*Owing to COVID-19, Kamen Rider Zero-One is the first series following Kamen Rider Ex-Aid to conclude with 45 episodes and, alongside Ex-Aid, it is the shared fifth-shortest Kamen Rider series overall.
*This is the first series to have its standalone film to be released after the end of the series, as Kamen Rider Saber would be airing at that time. The film was planned for a summer release, having been double-billed with Kiramager's standalone film. After a delay, both Zero-One and Saber's individual films had premiered that following December in lieu of a traditional Movie War between the two. Aruto would eventually meet Touma Kamiyama in , while Is would meet Reika Shindai in Kamen Rider Jeanne & Kamen Rider Aguilera with Girls Remix.
*This is also the first series to have an international airing start a week after the end of the series.
*An Indonesian dub premiered on RTV on October 28, 2021 https://twitter.com/langitrtv/status/1452971017953968134?s=21&t=F85VQyJzXga0kXOScpsdBA. The dub was made available on YouTube in the same year. The show received an English-style logo for the ads, different from the North American logo.
