Kazuki Nakashima (中島かずき): The Epic Storyteller of Stage and Screen

Introduction

Kazuki Nakashima (中島かずき) is the company writer of Gekidan Shinkansen (劇団☆新感線; the name is a homophone of shinkansen, the bullet train, written with different characters). For the company he has written period action plays alongside its rock-driven productions.

Winner of the 47th Kishida Kunio Drama Award in 2003 for Aterui (アテルイ), Nakashima is also an anime writer: he was head writer of Gurren Lagann and Kill la Kill, and wrote the film Promare.

Early Life and Career

Kazuki Nakashima was born in 1959 in Fukuoka Prefecture. In an interview with the Japan Foundation's Performing Arts Network Japan, he recalls joining his high school theater club because the school had no manga club, loving action stories from youth manga, and reading the romantic sagas of writers such as Shiro Kunieda, Ryo Hanmura, and Keiichiro Ryu.

After university he joined the publisher Futabasha, bringing his own manga to the interview. He worked there as an editor until 2010, writing for the stage at the same time.

Gekidan Shinkansen was founded in Osaka in November 1980 by students centered on Osaka University of the Arts. It is led by director Hidenori Inoue (いのうえひでのり), who directs its productions. Its work centers on original pieces set to hard rock and heavy metal.

Nakashima joined as company writer in 1985, and he has mainly written story-driven scripts for "Inoue Kabuki" (いのうえ歌舞伎), the company's series of period adventures drawing on myth and history.

The Kishida Prize-Winning Work

Aterui (アテルイ), 2002

Aterui draws on the real figure of Aterui (阿弖流為), an Emishi leader who resisted the Yamato court's expansion into northern Honshu. According to the historical record, he surrendered to the general Sakanoue no Tamuramaro (坂上田村麻呂) in 802 and was executed that year, despite Tamuramaro's appeal for his life.

The play was first staged in 2002 and runs about three and a half hours, with a cast of 42. The prize was given for the production starring Somegoro Ichikawa and Shinichi Tsutsumi at the Shinbashi Enbujo Theater.

In the Japan Foundation's summary, the Yamato kingdom turns north against the Emishi. Aterui, an Emishi man under a spell, meets the Yamato commander Tamuramaro in battle, and the two part as equals. Aterui regains his identity and leads the resistance, then surrenders to end the bloodshed. Yamato breaks its promise, and in the end he accepts defeat to end the war, extracting a pledge that the Emishi will not be attacked.

Nakashima has said that he had to make it "Aterui's story" for the work to succeed. He sees the demon (oni) as standing for indigenous people, but he does not treat the resisters as "in the right and therefore pitiable," aiming instead for a level playing field between rulers and resisters.

Theatrical Style and Philosophy

Nakashima's dramatic writing is characterized by several distinctive elements:

Action: Nakashima describes himself as fitting the label "action theater playwright," and Inoue as an "action theater director." He defers to Inoue on the visual side of the staging.

Rock music: Hard rock and heavy metal are basic to the Shinkansen style. In the company's "R series," original rock songs are played by a live band.

Kabuki: Nakashima says he had no earlier interest in kabuki, but found on reading and researching it that it was "very close to what we were doing in Shinkansen": plays written for specific actors, crowd-pleasing entrances, exaggerated gestures. Asked whether Namboku or Chikamatsu came to mind first among Edo playwrights, he chose Namboku.

Popular fiction: His stated influences lie in manga and saga novels. He drew on Futaro Yamada's novels for Hoshi no Ninja, for example, while finding Yamada's pessimism against his own nature.

Entertainment and theme: He has spoken of balancing thematic depth against entertainment value, so that audiences leave satisfied rather than with only pessimism.
