Both are adapted from Jun Ikeido novels. Though the leads are very different people (Hanzawa is an intense and almost samurai-like banker, Akamatsu a gentle yet steadfast everyman) each is pitted against the financial equivalent of Goliath. Conflicts of both dramas share a common theme and atmosphere, though Soratobu Taiya lends itself more to gray motivation and sentimentality. The promotional artwork is nearly the same, too.
