His stated motto is \"the world is a struggle to take; if it is take or be taken, I choose to take.\"[1](https://www.shopro.co.jp/license/title/316/) The people who come to him are those turned away by legitimate lenders: office workers, part-timers, sex workers, hosts, delinquent youths, and welfare recipients, whose fates begin to move once they borrow from Ushijima.[1](https://www.shopro.co.jp/license/title/316/)\n\nEach story arc centers on a debtor and traces how debt, desire, and desperation push the character downward, while Ushijima functions as the connective figure who appears in each episode.[7](https://dokode-mireru.sakura.ne.jp/drama/yamikinushijimakun/) The work is described by its licensor as a problem novel that realistically depicts the decline of people abandoned by mainstream financial institutions, and by the drama's broadcaster as confronting themes of social disparity and the working poor.[1](https://www.shopro.co.jp/license/title/316/) • [8](https://www.tbs.co.jp/tbs-ch/item/d1952/) Its social content has been used in Japanese sociology education, with the manga cited in university teaching on poverty, safety nets, precarious labor, and social stratification.[9](https://www.saniku.ac.jp/files/saniku_bulletin2022.pdf)\n\nThe title's \"-kun\" suffix takes its cue from the friendly names of consumer-finance automatic contract machines popular at the time, such as Acom's \"Mujin-kun\" and Aiful's \"Ojido-san.\"[7](https://dokode-mireru.sakura.ne.jp/drama/yamikinushijimakun/)\n\n## Publication and sales\n\nManabe began the series irregularly in *Weekly Big Comic Spirits* in 2004.[2](https://gigazine.net/news/20100809_ushijima_kun/) Circulation grew steadily across the franchise's run: promotional material for the 2012 film cited 5 million copies, the film's distributor cited over 6 million, and by the time of the 2016 final season Shogakukan's licensing site reported the total had passed 10 million.[10](https://www.youtube.com/watch?v=O3pYtuWC3HM) • [11](https://www.stardustpictures.co.jp/movie/ushijima.html) • [1](https://www.shopro.co.jp/license/title/316/) The manga won the general-category prize at the 56th Shogakukan Manga Awards in 2011.[1](https://www.shopro.co.jp/license/title/316/)\n\n## Television dramas\n\nThe first live-action adaptation was a late-night serial produced by MBS for the TBS network, nine episodes broadcast from October 12 to December 14, 2010, with Takayuki Yamada as Ushijima, Nana Katase as the drama-original character Chiaki, and Kyosuke Yabe as the loyal employee Karasawa; it drew a viewer rating of 2.3 percent.[3](https://asianwiki.com/Ushijima_the_Loan_Shark) • [8](https://www.tbs.co.jp/tbs-ch/item/d1952/) Producer Masatoshi Yamaguchi, who had earlier produced the Fuji TV finance-drama series *Naniwa Kinyudo*, conceived the adaptation after leaving Fuji TV in 2005 and persuaded the *Big Comic Spirits* editorial department almost immediately; because the protagonist ran an illegal lending operation, there were fears during production that the series might not be allowed on air at all.[12](https://yawaspi.com/ushijimakun/interview.html)\n\nSeason 2 returned in January 2014, again nine episodes on TBS/MBS, with Go Ayano joining as Inui and a storyline in which Kaukau Finance itself faces a crisis.[5](https://wiki.d-addicts.com/Yamikin_Ushijima-kun) Season 3 aired from July 2016 and, according to Yamaguchi, took on episodes of the original that had been called absolute taboos for live-action adaptation, bringing back the rival female [loan shark](https://www.edgepedia.org/loan-shark) Akane Saihara (Maryjun Takahashi) from the second film.[13](https://www.mbs.jp/ushijima/)\n\n## Films\n\nThe franchise produced four theatrical films, all directed by Yamaguchi and starring Yamada.[1](https://www.shopro.co.jp/license/title/316/) The first, a 129-minute feature released on August 25, 2012 and distributed by S.D.P, expanded the late-night drama into a violent, comic entertainment; it added Yuko Oshima as the freeter Miku Suzuki and Kento Hayashi as the event-circle leader Jun Ogawa, alongside a large new cast.[14](https://jfdb.jp/en/title/3187) • [11](https://www.stardustpictures.co.jp/movie/ushijima.html) It received the Cut Above Award for Outstanding Debut at Japan Cuts 2012.[14](https://jfdb.jp/en/title/3187)\n\n*Part 2* opened on May 16, 2014, adapting the manga's \"Yankee-kun\" and \"Host-kun\" arcs with Suda Masaki among the new cast.[15](https://jfdb.jp/en/title/6500) • [16](https://www.youtube.com/watch?v=n6RmbPVI418) In 2016 two films were released back to back: *Part 3* on September 22 and *The Final* on October 22, the latter a 130-minute conclusion that reveals Ushijima's origin and follows his former middle-school classmate Takemoto into a poverty-business dormitory called Junai no Ie.[15](https://jfdb.jp/en/title/6500) • [17](https://avex-pictures.co.jp/lineup/67704/) Counting dramas, films, and the spin-off, the live-action franchise ran to eight titles.[18](https://www.mbs.jp/saihara/)\n\n## Spin-off and afterlife\n\nA spin-off drama, *Yamikin Ushijima-kun Gaiden: Yamikin Saihara-san*, aired for 15 episodes on the MBS/TBS Dramaism slot from September 20, 2022, following Ushijima's rival loan shark Akane Saihara. It draws on both the main series and the side-story manga *Ramen Namerikawa-san*, which features Ushijima's arch-nemesis Namerikawa.[5](https://wiki.d-addicts.com/Yamikin_Ushijima-kun) • [18](https://www.mbs.jp/saihara/) Even after the 2016 conclusion, the series has continued to record high streaming viewership in Japan.[18](https://www.mbs.jp/saihara/)\n\nManabe's follow-up manga, *Kujo no Taizai* (*Sins of Kujo*), began serialization in *Big Comic Spirits* in October 2020 and had reached 15 volumes and more than 4 million copies in print when Netflix announced a live-action adaptation for its 2026 global lineup, produced by TBS and starring Yuya Yagira as the lawyer Taiza Kujo.[6](https://about.netflix.com/ja/news/sins-of-kujo-teaser) • [19](https://www.contentasia.tv/eNewsletter/2025/ContentAsia_eNewsletter_27_October_2025.pdf)\n\n## References\n\n1.
