Detonation: Violent Riders

July 2, 2010

Bakuhatsu! Bosozoku (Japan, 1975)

Detonation: Violent Riders is the first installment in Toei’s series of bosozoku biker gang films. Formed by youngsters grown tired of traditional Japanese school and societal systems, the bosozoku gangs received notable media attention in the 1970’s as newspapers and magazines cashed in with the phenomena and even took it out of its original frame. For Toei Studios, that had already been making money with their gang films for years, the bosozoku hysteria provided an opportunity to combine established cinematic formulas with a current and talked about real life phenomena.

Bosozoku’s roots date back to the post WWII years when a new societal problem group arised. Having lived under the war time rule and even an assumption of never returning home alive, such as the kamikaze pilots assigned for a mission that never came to be, some of the war veterans could not return to peaceful life without difficulties. The most extreme of these individuals started looking for new excitement by tuning cars and conducting less than desired, gang type activities on city streets. Inspiration and idols were found from foreign movies such as Rebel Without a Cause (1955). These ideologies later caught the motorcycle obsessed youth and bosozoku was born.

The first 20 minutes of the movie Detonation: Violent Riders is exactly what one would expect from a Teruo Ishii bosozoku film. Black dressed biker men chase on the streets, perform stunts on bikes and bring public outrage. A leather dressed lady provides the men with physical pleasures out in the nature, and the night is spent partying with topless dancers. Disagreements between men are solved by speeding towards cliff blindfolded. Ishii knows how to make quality cinema.

No high art by any means, Ishii directed the Detonation films as a gun for hire. Having first found himself somewhat bored with traditional filmmaking since the late 1960’s, Ishii ever since spend a notable amount his career – and Toei’s money – for his personal cinematic refreshment. The infamous Tokugawa-era torture epics are only the tip of iceberg in the director’s resume. In the Detonation movies Ishii threw in just about any elements he found potentially entertaining. Very describing of the director’s talent is, that even with this philosophy Ishii managed to deliver several technically competent cult classics.  Violent Riders, however, is not among his best efforts.

After a strong start it soon becomes obvious that Violent Riders’ biggest problem is the screenplay which, rather than being full of holes, appears to one big hole in itself. Pieces of poorly attached storyline are hanging somewhere on the sides, ready to fall at any moment.  If there is an actual plot to be found, it would probably be the romance between the wild hearted mechanic boy Iwaki (Kouichi Iwaki) and the innocent but gang tied Michiko (Tomoko Ai). The newcomer is quick to make enemies while at the same time his old pals are tempting him to re-join the gang and fight the competing group. The execution of this technically close-enough-to-decent plot is, however, far from dynamic and engaging.

Motorcycle money shots are what Ishii handles without difficulties. Close ups, sunset backgrounds and fast scenes on streets are plenty, even if there isn’t much in terms of bike tuning.  Worth a mention is also a jaw dropping truck crash escape stunt that does, however, turn out to be a trick shot with closer look. Far less convincing is the climatic gang war that is little more than a messy display of bikers riding in circle and kicking and punching each other on the way. Thankfully the film’s last few minutes mark an improvement and leave a good taste in the viewer’s mouth.

Next to the bikes Violent Rider’s best offering is the cast. Little known outside his native country, the soon to become television superstar Kouichi Iwaki handles the lead role with natural fluency. His manners and looks – in this film at least – mark him as a born to play gangster. Heavy weigh support is provided by Sonny Chiba whose beard-faced charisma is an instant hit. Regrettably, Chiba’s role is quite small and his action talent has been notably limited. Most other supporting actors are unknown stars and one-timers – real life gang members by a good guess. Toei’s executives have never been shy of picking up natural talents from the streets… and most of the time the results have been sufficient.

Ishii followed Violent Riders with two more gang films; Detonation: Violent Games (1976), and Season of Violence (1976). The series was, however, not buries after Ishii’s resignation but saw one more dawn under Yutaka Kohira’s direction in the film Detonation: 750CC Zoku (1977). Iwaki returned for all of the three sequels.


  1. This “motorcycle gang series” with Iwaki Koichi are on my wishlist. But only watched Bakuhatsu! Boso yugi on very poor quality.

  2. I’ve seen them all. The Toei dvds are very good. Having a bit of difficulties finding time to write, but I’ll try to cover them all.

  3. Yes, i saw they are in amazon.jp. Not so far i will publish some stuff of this movies!
