Over 200 people gathered recently on a hot day at a shrine in downtown Tokyo.
Many in the crowd were older adults. Some chewed gum and lifted dumbbells. The weight lifting was meant to increase their strength and balance.
The elderly Japanese had gathered for an event to mark Respect for the Aged Day.
The observance comes at a time when Japan's population is aging. The number of people aged 65 and over has grown to 27.7 percent of the population. That information comes from government reports.
The number of elderly Japanese who still work has also hit a new high. These numbers are evidence of efforts by the government and private businesses to keep the elderly at work.
The government estimates, released on Monday, are a sign of the problems resulting from a declining birthrate. Now, there are around 1.45 births for every woman in Japan. Many economists say a developed country needs a birthrate above 2 births per woman to prevent its population from shrinking.
Japan has struggled with a declining workforce for many years. The percentage of elderly people is among the highest in the Group of Seven Nations. Italy, for example, has an elderly population of around 23 percent. Germany has around 21.5 percent, while France has 19.7 percent.
In Japan, the government estimates that 35.14 million Japanese people are age 65 or older. 7.7 million of those men and women are still working.
For the first time, the number of Japanese aged 90 or older rose above two million.
