I am interested in learning about the current status of the restricted zone surrounding the Fukushima nuclear power plant, which experienced a nuclear incident in 2011. A specific map on a website depicts the area in question. I am curious to know if the area shaded in grey represents the restricted zone.
By "restricted zone," does it imply that residency is prohibited, but visits are allowed? From my observation on Google Maps, it appears that there are operational businesses, including restaurants, within this zone. Additionally, railway stations such as Namie are also in service.
So, what exactly are the restrictions within this zone? Can tourists or visitors explore these places freely, as long as they do not trespass on private property?
