Government figures show that nearly seven out of 10 postwar baby boomers in Japan will be aged 75 or older in 2023.

The internal affairs ministry estimates that the number of people born between 1947 and 1949 totaled more than 5.98 million as of October 2021.

Of these, more than 2.06 million people are expected to turn 75 this year, bringing the total in the age bracket to 68 percent of the baby-boomer population.

In 2025, all baby boomers will be aged 75 or older. That would raise the number of all those in the age bracket to about 20 percent of Japan's population.

As Japan's population quickly ages, the costs of nursing care are soaring year by year.

An expert panel of the welfare ministry started reviewing nursing-care insurance premiums paid by those 65 years or older last year.

The panel also considered raising the percentage of fees people pay out of pocket when they receive care services.

But no conclusions have yet been reached.

Ministry officials plan to make decisions by the coming summer so they can implement the revisions in 2024.
