Orcas: Mysterious Gathering at Shiretoko

Orcas are huge and powerful. That's why they're called the Kings of the Sea. But not a lot is known about the habits of orcas in the waters off Hokkaido Prefecture's Shiretoko Peninsula. Here they gather in great numbers and engage in a puzzling display, arraying themselves in straight lines. Using drones, underwater sound equipment, satellite transmitters, and other tools, marine researchers and NHK undertake an in-depth investigation over 2 years. They learn that the nutrient-rich waters off the coast of Shiretoko make the area a magnet for orcas. And the key to their mysterious behavior might be found in their highly developed social intelligence and strong family ties.

Tokyo's Lost Islands: Minami Iwo-to

In Tokyo, there are unapproachable "lost islands" with unspoiled environs and rich wildlife. Minami Iwo-to, part of the Ogasawara island chain, is about 1,300km from the Japanese capital. Normally, entry is banned to protect the environment. An exception was made in 2017 for the first comprehensive scientific survey in 10 years. The island compresses multiple climate zones into a small area, offering researchers a rare opportunity to view evolution in action. Braving an arduous climb and a swarm of seabirds, the team discovers one new species after another.

Tokyo's Lost Islands: Sofugan

In Tokyo, there are unapproachable "lost islands" where unspoiled environs cradle rich wildlife. Sofugan is a 100-meter-high solitary rock pillar standing in the ocean 650km south of the capital city's center. Remote and difficult to access, it had never been explored in detail. A group of scientists and engineers set out on a two-year survey. This program records their journey, along with the creatures they discover - from unusual species amongst the rugged rocks to mysterious marine life in the surrounding deep sea.

Decommissioning Fukushima Daiichi: Tackling Nuclear Fuel Debris

8 years after the Fukushima Daiichi disaster, a robot touched nuclear fuel debris deep inside the damaged facility for the first time. It was the initial step toward removing the highly radioactive debris, the greatest challenge in the decommissioning process. At the same time, more and more evacuees are returning, as Japan's government pursues the unprecedented task of rehabilitating communities while proceeding with decommissioning. We examine efforts to deal with the nuclear debris, and see how residents are doing now.

Nobel Laureate Salaryman: Staying Ahead in Science and Technology

Over the past few decades, the number of Nobel Prizes awarded to Japanese scientists has increased dramatically. They received 18 Nobels in the Natural Sciences category, gaining an international reputation for their scientific and technological capability. But in recent years, Japanese science and technology has become less competitive in the international arena. And Japan's budget for research has not kept pace with those in the United States and China, casting a dark cloud over the future. But Nobel laureate Koichi Tanaka is once again making waves with his ground-breaking research, after 16 years of relative obscurity as a company employee. How has Tanaka continued to innovate? We look into the struggle to keep Japan at the forefront of science and technology.

AI Robots: Friend or Foe?

From bartending to hotel room deliveries and fruit picking, robots equipped with artificial intelligence are making inroads into workplaces around the world. Some experts say that by 2030, robots will have taken over 30% of the work now done by humans. That would undermine one of the basic tenets of capitalism -- the promise that if you work hard, you will have a better life. In our program, we question whether the human race will be able to create a new form of capitalism that will allow people to coexist with automation technologies.

A Right to the End

The questions are simple yet profound. Would you prefer control over the manner of your death? Could you accept a wish for physician-assisted death on the part of a loved one? NHK was granted permission to follow 2 patients and their families as they grapple with the debilitating stages of incurable illness. Emotions run loose as all involved must confront the inevitable in their own way. Yet the very different outcomes specifically chosen by the patients focus as much on life as about a right to the end.

Death of a Dream: Vietnamese Workers in Japan

The Japanese government's Technical Intern Training Program, a solution to the country's severe labor shortage, is making it easier for people from other Asian countries to work in Japan. Some 1.46 million people from abroad are now working in Japan, many dreaming of a better life. But harsh working conditions, long hours, and even wage theft lead many to quit their jobs or even commit suicide. And they are often exploited by schools that charge high tuition but fail to provide an education. We explore the reasons behind this harsh trend and meet the Vietnamese monk who's trying to reverse it.

Police are still struggling to get a grip on Han-gure activities, with current laws targeting only designated crime syndicates. As Han-gure encroach ever deeper into the lives of ordinary people, we take a peek into the dark abyss of their world.
