Dai Saito (Matsumoto Hitoshi) may look like your average middle-aged chump, but he’s actually a superhero. When electrocuted, Dai Saito transforms into the gigantic, boxer-wearing Dai Nipponjin, doing battle against unsavory super-sized monsters like Jumpy Baddie, Baby Baddie, and of course Smelly Baddie. Saving Japan over and over again is all well and good, but Dai Saito doesn’t get much in return. Estranged from his ex-wife and daughter, he ekes out a boring life with a stray cat in a rundown house, waiting for the Department of Defense to call him to superhero action (for middling pay). All his battles are broadcasting on television, but the public couldn’t care less for his patently unstylish look and his neighbors all-out hate him. With plummeting TV ratings and bleak prospects ahead, can this superhero save himself?
