The government in Fukushima, Japan released drone footage Thursday showing the progression made in the area’s rebuilding process six years after an earthquake, tsunami and nuclear meltdown devastated the region. The videos showed a multitude of areas in the prefecture, including Iwaki City, about 30 miles south of the Fukushima plant, and Futaba, a town 11 miles north of the plant.

The videos also showed reconstruction on roads and coastlines, areas severely damaged by the earthquake and tsunami.

The government has been working for six years to revive the area. Earlier in May, a bill was enacted to accelerate reconstruction by using state funding to aid the decontamination process in certain districts, according to the Japan Times. The prefectural government announced recently it had made “tremendous progress” in revitalization efforts, allowing some residents to return to evacuated areas.

Officials began welcoming residents back to towns nearby the defunct power plant in April, six years after 160,000 residents were evacuated from a 310 square mile uninhabitable zone. The region was rendered uninhabitable after an earthquake and tsunami hit in 2011, breaching the nuclear plant’s seawall and causing a massive meltdown. The ensuing nuclear disaster was the worst the world had seen since Ukraine’s Chernobyl in 1986.

In the years since, the plant’s operator, Tokyo Electric Power Company (TEPCO), has worked to clean and decommission the facility. The company estimated that the entire process would likely take decades at a cost of $188 billion.

At one point in February, officials announced they were struggling to locate nuclear fuel debris inside one of the plant’s reactors that had caused radiation levels to skyrocket. Cleaning robots deployed by the company had to be pulled out of the plant after they ceased to function due to the excessive radiation.

But TEPCO has made progress — in April the company announced that workers at the plant were finally able to shed some of the heavy protective gear that was previously necessary. The company said the 7,000 workers employed there were now able to wear regular uniforms at about 95 percent of the site.

In addition to decommissioning the plant and cleaning nearby areas, workers were confronted with some rather unconventional tasks as well. As areas surrounding the plant laid barren following evacuations, wild boars descended from nearby mountainsides to invade the area.

“After people left, they began coming down from the mountains and now they’re now going back,” Soichiro Sakamoto, a hunter who was employed to exterminate some of the animals, told Reuters in March. “They found a place that was comfortable. There was plenty of food and no one to come after them.”

Though the reconstruction process in the prefecture has made strides in the past six years, it’s unclear just how many residents will choose to return to the area. A government survey released in 2016 found that more than half of the residents of a town near the plant said they wouldn’t return, even after evacuation orders were lifted.

“We have caused it,” Daisuke Hirose, a spokesman for TEPCO, told the Japan Times in April. “We have to make every effort to create a place to which people want to return.”
