Just when you thought it was safe to go back to the onsen, prehistoric sharks decide it’s time to strike back against unsuspecting bathers. Is it really so wrong to want to relax in some nice, warm water or are we actually invading the sharks’ territory? In any case, Morihito Inoue’s creature feature Hotspring SharkAttack (温泉シャーク, Onsen Shark) is as much about the ravages of capitalism as it is about aquatic terror as the social media-obsessed mayor fixes his sights on saving the town through a massive onsen complex.
Tellingly, many of the local people are against the plan, which will have profound effects on their livelihood, while many of the local politicians are reluctant to close the onsen despite knowing about the shark issue in much the same way the mayor in Jaws refuses to lose the beach because they don’t want to risk damaging the tourist industry. When they do eventually close them, little children cry to their mothers about not being allowed into the baths, which just shows how important hot springs culture is to this area.
But then it is quite weird, sharks suddenly snatching people from the baths and somehow dragging them back to sea. Modern science has an answer, thanks to top sharkologist Mayumi (Yu Nakanishi), but it’ll take a bit longer to find a way to stop them getting in while Mayumi agonises about her role in the proceedings as a lover of sharks yet essentially responsible for their destruction. A part of her still wants to find a way to coexist peacefully even as the sharks wreak havoc on the town and continue to pose a serious risk to life. Even so, the area ironically becomes a tourist hotspot after all as a swarm of live streamers arrive to try to experience the shark-infested waters for themselves despite the danger.
Meanwhile, the sharks’ gills light up like the onsen symbol on maps while the mayor is haunted by the spirits of his ancestors and also wears a tie with little onsens on it. He later thinks better of his sleazy capitalist ways and comes to the realisation that it’s his responsibility to save the town even if that means torpedoing his landmark new resort and acknowledging the harm it would do to the local area. It seems that these prehistoric, super squishy sharks only got woken up because of global warming which is why they’re drawn to warmer waters and able to terrorise innocent onsen-goers.
The same might be said of Maccho, a very buff guardian of onsen culture who can’t remember who he is or why he was born but is committed to defending protecting hot springs everywhere. Everyone in the town is keen to protect them too, and not just because they drive the local economy. The police chief’s about to retire with a vague idea about becoming a novelist but is still determined to clear up the shark problem, while his assistant later fights off a bunch of sharks single-handed to give the others time to do their thing.
Unable to use guns because these sharks are also full of methane, this particular issue requires a less conventional solution, though the irony is that it lies at the heart of the problem. The weird disease the sharks starts spreading can only be cured by an antidote found within their own fins. The government might be content to simply destroy the town first, hinting at the indifference of the Tokyo elite to small-town disaster, but the local community won’t let that happen and nor will the hot springs guardian. Inoue adds in a fair degree of absurdity in order to make his central conceit work including a series of weird gags about eating a sub on a sub while harnessing the reality of his low budget to add a note of surreality to the town. The sharks themselves have a pleasingly retro design while the practical effects add to the sense of absurdity right down to the cute little submarine the team eventually constructs using the 3D printer that was designed to build the soulless onsen complex with its rooftop pool and ill-advised bungee jumping facilities. If there’s one thing that Hotspring SharkAttack has, it’s genuine heart along with small-town pride and a sense of fun that actively revels in the ridiculousness of its premise.
Hotspring SharkAttack screens 31st May as part of this year’s Nippon Connection.
