It was initially reported on websites and magazines under the tentative title of "Together for a Long Time: The Story of Voice Actress Nobuyo Ōyama" ("Zutto Issho Dayo ~Seiyū Ōyama Nobuyo Monogatari~").
When she was initially offered the role of Ōyama for the drama, Suzuki felt a huge mix of surprise and joy, as she had never portrayed someone different than her and that while she was a cat person, never expected to be able to portray Ōyama. She wondered for a bit if she could even take on the role before deciding to accept because she wanted to "express how the 'Doraemon' character we are all familiar with today was actually created."
Suzuki did not try to replicate Ōyama's voice for her performance from the beginning, as she felt it was a "one-of-a-kind voice" and wanted to portray Ōyama as "not just a voice actress, but a woman." She didn't particularly think about reading references to help build the character because she's read Doraemon manga ever since she was a child. She consulted co-star Kōsuke Toyohara, who portrayed Ōyama's husband Keisuke Sagawa in the drama, on how to respectfully portray specific aspects of Ōyama's life as a woman such as her struggles with infertility and aimed to show how Ōyama was able to serve as a maternal presence in children's lives and bring joy to them through the character of Doraemon.
Regarding the pressure of portraying both Doraemon and Ōyama, Suzuki said, "The excitement of getting to play Nobuyo Ōyama, whose voice and appearance are completely different from my own, came first."鈴木砂羽、大山のぶ代役に「難易度高い」ドラえもんボイスに苦戦 (in Japanese). Drama & Movie by Oricon News. Oricon News official website. November 25, 2015. Retrieved June 3, 2026.
She then reflected, "Of course, I knew she was battling an illness, so I was shocked at the time, but I guess an actor's spirit just takes over. Since our voices are completely different, I was filled with curiosity and excitement about how the director, myself, and the rest of the cast would bring this all together."
In late November, a press conference was held in Tokyo, with the main cast members for the drama attending.ドラえもん声優・大山のぶ代の半生描くＮＨＫＢＳドラマ プロレスラー・小川直也のあだ名はやはり「ジャイアン」だった… (in Japanese). The Sankei Shimbun. The Sankei Shimbun official website. November 29, 2015. Retrieved June 3, 2026. There, a producer on the drama revealed that the actors were cast in their roles based on the Doraemon characters the voice actors portrayed rather than the voice actors themselves. Taku Suzuki, the actor who portrayed Kaneta Kimotsuki in the drama, was surprised upon hearing, as he had been "verbally abused" on Twitter when it was announced that he would be portraying Kimotsuki in the drama. He then revealed that he was referred to as Doraemon character Suneo throughout his elementary school, junior high, and high school years, much to the surprise of the other cast members, who reacted with surprise and telling him that he does resemble Suneo. Suzuki then expressed his delight in "having become Suneo", as he has admired the character ever since he was a child, before remarking with a serious look to "please stop saying bad things about me on Twitter", which made the venue laugh. Naoya Ogawa, the actor who portrayed Kazuya Tatekabe in the drama, then said that when he received the offer to portray Tatekabe, he "knew he wanted to do the part," as his nickname has been Gian ever since he was in elementary school. The rest of the cast members burst into laughter at this and remarked at how they knew it and that he had even resembled the Doraemon character of Gian.
One day before the drama's premiere broadcast, Misato Tanaka, the actress who portrayed Michiko Nomura in the drama, posted on her online blog about how she hoped through her performance as Nomura that she'd be able to get closer to Nomura's "strong, gentle and lovely" personality and image.
The drama is based on three books, "My Interesting Life" (Watashi no Omoshiro Jinsei) (Kosaido Publishing, ISBN 978-4-3315-0178-8), published in 1984, "My Wife is Doraemon" (Kami-san wa Doraemon) (Futabasha, ISBN 978-4-5752-9295-4), published in 2001, and "I Was Doraemon: 26 Years of Tears and Laughter" (Boku, Doraemon Deshita: Namida to Warai no 26-Nen Uchiaobanashi) (Shogakukan, ISBN 978-4-0938-7654-4), published in 2006.
Release The television drama premiered in Japan through the NHK BS Premium channel's "Premium Drama" programming block on December 13, 2015.
