Today's Close-Up

For many elderly Japanese, a car provides vital access to daily necessities and essential services. While many remain confident in the safety of their driving, their families often become concerned with the decline in their cognitive and physical functions. Should they keep their driver's license or give it up? It's a question given added urgency by a spate of accidents involving older drivers. Researchers are hoping to provide an answer with a new body of data-driven work that has given rise to the idea of the "driving lifespan" - the years during which someone can continue to safely operate a vehicle. We take a look at what the latest science shows and ask an expert what people can do to extend their driving lifespan as much as possible.

Gold prices continue to soar worldwide. Amid this unprecedented boom, international operators are conducting exploratory mining around closed gold mines in Japan. Meanwhile, competition is intensifying to extract gold from used electronic devices. While efforts to acquire gold are accelerating in some countries around the world, problems such as the spread of illegal mining are also arising in Africa. What will this new gold rush bring to the world, and to us?

As the world continues to shift from handwriting to digital input, in Japan, an increasing number of people are forgetting how to write some kanji characters by hand. Recent studies show handwriting can help stimulate the brain and prevent cognitive decline. Indeed, schools in countries like Sweden and the United States are allocating more time on classes where students learn through writing by hand. With our guests, we explore the value of handwriting in this digital age.

Japanese people are increasingly living longer lives, but the change is not always a welcome one. For many, the progression into old age, and the accompanying decline in bodily functions, results in continence issues. 
Many are reluctant to acknowledge the problem or accept outside help on such an intensely private matter. We asked experts how carers and loved ones can support people dealing with toileting issues, and consider how the elderly themselves can embrace a positive shift in perspective to get the most out of their final stage of life.

Sushi is enjoying a global boom, but it's a different story back in Japan. Dwindling catches of local fish and intense competition for foreign customers have polarized the domestic industry. High-end restaurants and popular chains are thriving, but local restaurants have been pushed to the brink. Some experts worry the future of sushi culture is at risk. But in some corners, efforts are underway to preserve the traditional cuisine and modernize its appeal. We take a close look at the new era of sushi.

Demand for private lodgings known as minpaku is on the rise, with approximately 36,000 across Japan at present. A series of problems with trash and noise have led to moves by local governments to tighten regulations. While unexpected changes are underway, exploration is also ongoing to utilize private lodgings that are rooted in the local community. What should the future hold for private lodgings? We consider the current situation as they stand at a crossroads.

The struggles of everyday life are driving more and more people to use AI chatbots to fill the void in their hearts. Attracted by the sense of support and the constant availability, some have even 'married' AI characters, or recreated deceased partners to fill the feelings of loss. Meanwhile in the US, there have been cases where bereaved families have sued AI companies, claiming that the bots caused loved ones to take their own lives. We look into the way people use AI, along with some precautions it might be wise to take.

Hospice-style housing is emerging as a new end-of-life housing option for people with terminal or incurable illnesses in Japan. These residences offer a level of comfort and care unavailable at nursing homes, and they are spreading rapidly at a time when hospital capacity is declining across the country. But they also present serious challenges. The quality of care varies dramatically by residence, and some operators have been known to overcharge for medical care. We talk to experts about the merits of hospice-style housing and what needs to be done to improve the system.

In January 2026, the Nara District Court delivered a life sentence to Yamagami Tetsuya who assassinated former Prime Minister Abe Shinzo. A focal point of the trial was how much consideration would be given to the upbringing of the defendant who'd been struggling due to his mother's adherence to the former Unification Church. In this program, NHK interviews children of Church followers with backgrounds similar to Yamagami's, who share their views on the trial. We also speak with someone who met with Yamagami for a total of ten hours, religious studies expert Sakurai Yoshihide, and hear what the defendant told him.

Research has found that chewing ability is closely connected to healthy lifespan and brain stimulation. At the same time, data suggests there has been a decline in chewing strength across Japan, a trend that experts attribute to changes in the modern diet, among other factors. The result has been a greater prevalence of underdeveloped jaws in children, and increased frailty and health problems in older adults. We spoke with experts, who explained how consistent oral training and mindful eating can boost our focus and ensure a longer and healthier life.

Guest: Teruyama Yuko (Dentist and Doctor of Dental Science)
