The characters' ages in the anime "Smoking Behind the Supermarket with You" are a key detail that adds realism to the plot and confirms fans' suspicions about the two main characters. The 2026 anime adaptation by Crunchyroll tells the story of a touching, slowly developing romance between two lonely adults, Sasaki and Yamada, after they develop a genuine, unobtrusive connection during shared smoke breaks behind the supermarket.
One of the main topics of discussion among fans of the anime "Smoking Behind the Supermarket with You" is the ages of the two main characters. The official synopsis for the anime, released on Crunchyroll, confirmed that Sasaki, a stressed-out office worker, is 45 years old at the beginning of the anime and manga.
«At forty-five, office worker Sasaki is tired of the corporate grind. His only solace is a cigarette and the welcoming smile of supermarket cashier Yamada. When Sasaki can't find Yamada after a particularly tough day, a striking woman invites him to join her for a smoke. The dejected man thinks he's found a new smoking buddy in the cool and playful Tayama, but Sasaki doesn't realize he already knows her!»
However, the manga of the same name confirms that the characters' ages actually increase as the story progresses, rather than remaining constant. Chapter 29 of the manga confirms that Sasaki is 46 years old, meaning he was 45 in the previous chapters.
Meanwhile, at the beginning of the story, Yamada is 24 years old, which is the same age she started working part-time at the supermarket eight years ago, around age 16. In that same chapter, 29, she turns 25.
This age difference essentially creates an initial 21-year age gap, but it's worth noting that the story itself approaches this with self-deprecating irony. It explicitly states that both are consenting adults, and their relationship develops based on shared emotional understanding, rather than being rushed (like a casual affair).
By comparison, the age difference between some characters in other well-known series like The Good Girl's Guide to Murder, The Summer I Got Pretty, and Heat Rivalry isn't that big.
The characters' birthday sequence adds a nice layer of time-passing to this otherwise quiet and unobtrusive episodic series.
The comic "Smoking Behind the Supermarket With You" began as a webcomic on X in 2022 and later began serialization in Square Enix's Monthly Big Gangan magazine. An anime adaptation began streaming on ABEMA Premium for subscribers in Japan on June 3rd of last year, with regular airings scheduled for July.
Why the age difference between Sasaki and Yamada is a compelling plot device.
The 21-year age gap between Sasaki and Yamada in Smoking Behind the Supermarket with You actively influences the tone and character dynamics, making the story mature and fresh in the age gap romance genre.
Sasaki is portrayed as a tired, insecure office worker, worn out by decades of corporate routine, while Yamada is portrayed as a young but disillusioned part-timer who has worked at the same supermarket for nearly a decade. The 21-year age difference highlights how two adults at completely different stages of life can find profound emotional resonance in each other.
Sasaki is also aware of the age difference, and this is, in fact, a central character trait. He even repeatedly downplays any romantic possibilities, considering himself too old and exhausted to pursue a younger woman. This internal hesitation is intentional and adds humor and tenderness to the unique story.
Meanwhile, Yamada often takes the initiative and teases, giving her a clear role in their relationship. Her portrayal of a confident and insightful woman inverts the typical dynamics of relationships between people with a large age gap, as it is the younger heroine who determines much of the emotional development of their relationship.
Overall, the age gap serves as a solid storytelling foundation that underpins the show's core strengths: authenticity, emotional restraint, and the quiet joy of unexpectedly meeting someone who understands your everyday struggles.
