Being stood up is a painful experience at the best of times, but when you’ve been in prison for three whole years and no one comes to meet you, it is more than usually upsetting. Sixth generation Oyabun of the Ona clan, Daisaku, has made a new friend whilst inside – Taro is a younger man, slightly geeky and obsessed with bombs. Actually, he’s a bit wimpy and was in for public urination (he also threw a firecracker at the policeman who took issue with his call of nature) but will do as a henchman in a pinch. Daisaku wanted him to see all of his yakuza guys showering him with praise but only his son actually turns up and even that might have been an accident.
His mistress has moved on, his wife got religion, and the clan has gone legit and formed a corporation. That last bit might have been OK except Daisaku isn’t the president, he’s the Chairman, and the new top dog is a pen obsessed political candidate who runs under the slogan that pens can save Japan and violence is the enemy! Taro and Daisaku come up with a way to get revenge on the usurper by sneaking a bomb into one of his beloved writing implements but it’s far from plain sailing in this typically anarchic Okamoto world.
Okamoto casts his ironic tale as a musical, cartoon style slapstick comedy with frequent digressions into musical interludes which take inspiration both from Hollywood movie musicals and classical Japanese drama. Daisaku may only have been inside for three years but he’s a man out of time with behaviour and attitudes more suited to the pre-war world than the modern era. Consequently he often breaks into theatrical rhythms inspired by noh or kabuki with their characteristic chant style recitative and stylised movements. Younger characters sing in the vernacular of the day with Taro and Daisaku’s son belting out a popular hit, and the office workers suddenly breaking into a musical set piece themed around the idea of overtime in which the men and women of the office bicker about balancing the books. Similarly, the would be mayor, Yato, takes his cues from ‘20s gangsters so he naturally dances the charleston before breaking into a tango when he gets some unwelcome news.
Rhythm is the key as the film continues to respond to its various musical fluctuations in highly stylised approach which takes advantage of Okamoto’s innovative editing techniques. Apparently inspired by a Cornell Woolrich story, this is nominally a noir inflected crime story of an ousted gangster trying to rub out his rival and get his old life back, but Okamoto neatly deconstructs the genre and turns it inside out with a hefty serving of irony on the top. Daisaku is an old guy and his era has passed, but Yato isn’t real enough to represent the future either which seems to either belong to bumbling bomber Taro, or Daisaku’s hardworking and straightforward son.
The plot to blow up Yato using his favourite prop becomes progressively more ridiculous as the pen ends up everywhere but where it’s supposed to be and threatening to explode at any second (to great comic effect). Things get even darker when Yato is talked into considering the orchestration of an “accident” for his mayoral rival involving a golf ball which once again causes everyone a lot of bother (though not the kind that was intended).
Daisaku has brought some of his old fashioned habits out of jail with him, quickly corrupting his old friend the chauffeur (who ultimately proves incorruptible even if grateful to have been reminded of the happiness he already shared with his wife, poverty or no) and allowing Taro and his crazy bomb plots access to the criminal mainstream, but ultimately he proves more of a loveable rogue living in the past than a criminal mastermind. Yato, by contrast, is a darker figure with his hypocritical campaign slogans and lack of personal integrity. Daisaku may be deluded in many ways but he never pretends to be anything other than he is, unlike the would be dictator.
Filled with Okamoto’s idiosyncratic touch of absurd irony, Oh, Bomb! (ああ爆弾, Aa Bakudan) is one of his most amusing and formally ambitious pieces of work. Mixing classical theatrical techniques with modern movie musicals, jazz rhythms, expressionist sets and unpredictable editing, he once agains creates a crazy cartoon world in which anything is possible but somehow it’s all quite good natured even when you’re talking about bank robbery and possible assassination plots. Hilarious fun but also intricately constructed, Oh, Bomb! ranks among Okamoto’s most charming masterpieces and is urgently in need of a reappraisal.
Kihachi Okamoto first made his name with his samurai movies but his output was in fact far more varied in tone than the work most often screened outside of Japan might suggest. Marked by heavy irony and close to the bone social commentary, Okamoto’s movies are nothing if not playful even in the bleakest of circumstances. He first teamed up with Japan’s indie power the Art Theatre Guild for
