1122: For a Happy Marriage

About this title

Based on Peko Watanabe's manga of the same name, this drama follows a couple in their seventh year of marriage who live under a mutually agreed rule permitting the husband to have an extramarital relationship, and who begin to re-examine their relationship as that rule starts to waver.

Prime Video released the series as a worldwide exclusive, rolling out all 7 episodes in three installments: episodes 1–3 on June 14, 2024, episodes 4–5 on June 21 and episodes 6–7 on June 28. In Korea, Prime Video lists it under the Korean title 1122: 좋은 부부. The original manga by Peko Watanabe ran in Kodansha's Morning Two from 2016 to 2020 and was completed in 7 volumes. Its circulation had passed 1.46 million copies as of November 2023, when the drama adaptation was announced, and as of October 2026 Kodansha's official description puts it at over 2.1 million copies, print and digital combined. The theme song is Spitz's "i-O(Shuri No Uta)."

The series is directed by Rikiya Imaizumi, who has delicately portrayed romance and human relationships in films such as What Is Love?, Over the Town, By the Window and Undercurrent. The screenplay was written by his wife, Kaori Imaizumi, a filmmaker who directed the feature Just Pretended to Hear (2012), and this is the first time the two have worked together as director and screenwriter. Kaori had been away from filmmaking for more than 10 years, and during the years when Rikiya struggled to make a living, she supported the household as a nurse. Rikiya has said he wanted his wife to return to the world of filmmaking. The script took shape with Kaori writing the plot and first draft, and Rikiya adding his input to refine it. The series was planned and produced by Junko Sato, with murmur as the production company.

Mitsuki Takahata plays Ichiko Aihara, a web designer, and Masaki Okada plays her husband, Otoya Aihara, who works for a stationery company. The couple have not had sex for 2 years, and at Ichiko's suggestion they follow a rule under which Otoya spends the night of the third Thursday of every month with his lover. In episode 1, Ichiko makes advances to Otoya on a trip for their 7th wedding anniversary and is turned down, and her friend Kei (Kurumi Nakata) tells her that she, too, has the right to an extramarital relationship. In episode 2, Otoya's lover is angered to learn that their relationship had been sanctioned by his wife, while Ichiko meets Rei (Hokuto Yoshino), a therapist at an establishment catering to female clients. Nanase Nishino and Kengo Kora play the Kashiwagis, Otoya's lover and her husband, and Ryo Narita plays Godai, Ichiko's friend from university.

Rikiya Imaizumi has described the series as a story about people who love earnestly, yet clumsily, in order to stay with the person beside them, while Kaori Imaizumi explained that she tried to preserve the heart of the original by centering it on the question of "what makes a good married couple." Masaki Okada said that although the work itself is a sensitive, edgy story, he sees it as the story of a married couple getting back on their feet. Mitsuki Takahata said she had previously read the manga and wanted to see it as a drama, but thought that with so many challenging scenes it might not be possible to depict it fully on network TV, so she was truly happy when she was later offered the role of Ichiko in a streaming drama. The two leads, who appeared together for the first time in this series as husband and wife, each announced their marriage on Instagram on November 19, 2024.
