Tokyo Gov. Yuriko Koike on Tuesday pledged greater support in child and nursing care to address growing social needs as the nation seeks to deal with its shrinking and graying population.

Koike, in an interview with The Japan Times, also said she will do more to improve the capital's living environment to improve Tokyo's status as a global hub.

"In 2025, five years after the 2020 Olympic and Paralympic Games, the population is projected to peak, and the baby-boomer generation will reach 75 years of age or more, and we will witness a rapidly aging society," Koike said. "Tokyo is also seeing an exceptionally low fertility rate, which is why I want to focus on people's needs."
