Premise

The series follows Kiyoshi Oze, a physically powerful but careless young man who joins a sumo stable and, as the wrestler Enzou (猿桜), climbs the ranks while charming fans with his abrasive behavior and shaking a sumo world built on tradition and formality.¹ The title refers to the dohyo, the ring where sumo bouts take place, described in the series' own synopsis as a "sanctuary" (聖域) that has hosted sumo as a traditional culture and Shinto ritual for more than 1,500 years; the story places a cornered, reckless young man seeking money, women, and fame on that sacred ground.⁸

A second thread follows Asuka Kunishima, a sumo-beat journalist played by Shiori Kutsuna, whose reporting brings the audience into the sport's back rooms; her editor Tokitsu is played by Tomorowo Taguchi.²^•⁸ The South China Morning Post described the pairing as a bad-boy wrestler teaming up with a hard-nosed journalist, with Oze written as a former judo champion who takes up sumo.⁹

Cast and characters

Wataru Ichinose, previously seen in supporting tough-guy roles, plays the lead.¹ The supporting cast includes Shota Sometani as Shimizu (Masaki), Shiori Kutsuna as Asuka Kunishima, Kitaro as Koji Oze, Katsuya Maiguma as Ryuji Yasui, Hiroki Sumi as Shizuuchi, Sō Kakukaku? (Kaku Ryuki played by Sō Kaku), Akito Inui, and the comedian Omusubi, with Yoko Maki, Goro Kishitani, Akira Nakao, Toshi Shiozawa? (Takashhi Sasano), Matsuo Suzuki, Koyuki, and Pierre Taki in further roles.⁸^•³

Shizuuchi, Enzou's silent rival, is played by Hiroki Sumi, a real former professional sumo wrestler (Hishofuji Hiroki); Tokyo Weekender noted that the character never utters a single word yet reads as vulnerable, dedicated, broken, and terrifying thanks to the writing.¹⁰

Sequel status

No second season has been announced. As of 2026, Netflix's own page lists the title only as "2023, 8 episodes", and Japanese streaming guides report that no continuation has been announced; the lead actor said in a summer 2025 television appearance that the sequel situation was still undecided.¹^•⁷^•²

Production

The project began when a Netflix producer contacted Eguchi after seeing his 2018 film Gachi Boshi? (Gachi Boshi is not the title; the film was Gachi Boshi... ) — the contact followed Eguchi's 2018 film debut, and the script then took more than a year to develop.⁴^•¹¹ Netflix executive producer Kazutaka Sakamoto described the process: Eguchi and Kanazawa came to Netflix "like dojo-breakers" about two and a half years before release, the script was developed over more than a year, actors were chosen by audition, and the cast underwent about a year of physical transformation and more than six months of sumo training.¹¹ In interviews Eguchi put the total preparation at four and a half years.⁴

Kanazawa said on RKB radio that what he set out to write was "the Shiroi Kyotō (The Great White Tower) of the sumo world", a drama about the inner workings of an institution, and that he had expected the sport's masculine image to limit its audience.¹² Eguchi said the production team kept a "documentary perspective" in mind throughout, and worked to keep sumo's unusual rules from interrupting viewers' concentration in both script and editing.¹³

The opening title sequence, directed by Kei Uehara of the production company KOO-KI (which Eguchi founded in 1997), won a Bronze in the Film Craft category at the Cresta Awards 2024.⁶

Reception

The series entered Netflix's weekly global Top 10 in its first week (May 1–7, 2023) at No. 6 worldwide and No. 1 in Japan, and Eguchi reported that its momentum had not faded two months after release.⁴ In December 2023 it won the Best Screenplay (top prize in the category) at the Asian Academy Creative Awards, described by Mynavi as one of Asia's largest creative competitions.⁵ On the Japanese review aggregator Filmarks it holds a 4.1 average from 46,935 user reviews.¹⁴

English-language critics were more divided. The Japan Times called the series an ambitious attempt to depict sumo at a professional level but judged that the bad-boy wrestler's journey did not fully pack a punch.¹⁵ Tokyo Weekender called it a rare fictional story about sumo in Japanese entertainment and an "imperfect love letter" to the sport.¹⁰ The Washington Examiner praised the show for carrying the intricate, hierarchically ranked world of sumo, with its six divisions and hundreds of athletes, to an international audience.¹⁶
