Zipang takes a more realistic look at how a modern military ship from our time would interact with a period in time where the world was fighting itself. We watch as Mirai's crew tries to alter history, and as they scavenge for food. While some parts are off, or inaccurate, it manages to overall potray a lifelike scenario. The characters themselves can be bland, and at times, uninteresting, but its not over the top. Theres no big eyed anime girls to be found, or SDF worshipping like GATE, but rather an actual scenario that could be expected. Overall, it can be boring at times, but ithits just right.
