Ginko is a Mushishi - an expert on Mushi, odd spirit-like creatures not everyone can see and that occasionally cause harm to unwary humans. Ginko travels Japan studying Mushi and helping solve problems related to them, such as a village paralyzed by rust mushi, or a bamboo mushi that traps travelers in its forest. Each episode stands on its own, telling of a different place with different mushi, with Ginko observing and assisting when needed.
This is a very languid, beautiful series. Ginko does have a backstory that is eventually revealed, but the series focus is individual episodes. The scenery and mushi combine to create a delightful viewing experience, and the stories are engaging, quickly drawing you in to the world they create. Watching this show made me feel relaxed and I came away from each episode with a contented, peaceful feeling. Not that the stories are boring - since Ginko is a healer-like character, most of the stories involve people who are suffering from their contact with the mushi. But the resolutions are normally uplifting and satisfying.
If you are looking for an action show, this is not it. If you are looking for a show that has an continues storyline, this is also not it. But if you want a show that you can just watch and enjoy on an episodic basis, that has emotional stories and beautiful scenery, please give this show a try. So far everyone I've showed this series to has enjoyed it, and I hope you will too!
Random Trivia: "Mushi" is the Japanese word for "bug", which is what the mushi of this show often resemble.
