If you're a resident of Chiba Prefecture, you can get some ideas for day-trips from this. Apart from that, this short-series has near-zero plot or substance. It is a tourism promotion anime made on the occasion of Chiba Prefecture's 150 year anniversary, but not really relevant to any foreign visitors - since you can see the types of places featured in this basically anywhere in Japan, and I don't think they're going to mention Tokyo Disneyland (which is technically in Chiba). Chiba is a nice place, but probably not worth specifically coming to Japan for, maybe on a detour from Tokyo. If you do planto, you might want to give this a quick look; the individual episodes are just 3 minutes long after all.
