A Japanese nappy maker has announced that it will stop producing diapers for babies in the country and, instead, focus on the market for adults. Oji Holdings is the latest firm to make such a shift in a rapidly ageing Japan, where birth rates are at a record low. Sales of adult nappies outpaced those for infants in the country for more than a decade. The number of babies born in Japan in 2023 - 758,631 - was down by 5.1% from the previous year. It was also the lowest number of births on record in Japan since the 19th Century. In the 1970s, that figure stood at more than two million. Meanwhile, the adult diaper market has been growing and is estimated to be worth more than $2bn (£1.6bn). Japan now has one of the world's oldest populations, with almost 30% of them aged 65 or older. Last year, the proportion of those aged above 80 surpassed 10% for the first time. A shrinking population, the result of both ageing and plummeting birth rates, has become a crisis for Japan, one of the world's largest economies.
