Japan is defusing its demographic time bomb, but the US is building one of its own

Kosuke Mori, a three-month-old baby, is fed by his mother as Satoru Saito (not pictured), general manager of Pigeon Corp's R&D centre, conducts a research on how babies drink milk, at Pigeon's facility in Tsukubamirai, Ibaraki prefecture April 4, 2014. Pigeon Corp's researchers are on a high-tech quest - to perfect a baby's bottle teat that replicates a breastfeeding mother's nipple. Pigeon, founded almost 60 years ago, sells about 100 million bottle teats a year and has a more than 80 percent share of the Japanese market. As the country's birth rate declines, the company has moved overseas and hopes to have 50 percent share of the baby bottle teat market in all major international markets by around 2020, according to a note by Shared Research.
