What do you make of this? It's difficult to notice demographic changes, but the trends in Japan are similar to what will happen in other developed countries.
There are special nursing homes in Japan that offer service and assistance to more than 30 residents. In 2008, it was recorded that there were approximately 6,000 special nursing homes available that cared for 420,000 Japanese elders.[49] With many nursing homes in Japan, the demand for more caregivers is high. In Japan, family caregivers are preferred as the main caregiver because it is a better support system if an elderly person is related to his/her caregiver. Therefore, it is possible that Japanese elderly people can perform activities of daily living (ADLs) with little assistance and live longer if his/her caregiver is a family caregiver.[49]
Many elderly people live alone and isolated, and every year thousands of deaths go unnoticed for days or even weeks, in a modern phenomenon known as kodoku-shi (孤独死, "solitary death").[50]
The increasing proportion of elderly people has a major impact on government spending and policies. As recently as the early-1970s, the cost of public pensions, health care, and welfare services for the aged amounted to only about 6% of Japan's national income. In 1992 that portion of the national budget was 18%, and it is expected that by 2025 28% of national income will be spent on social welfare.[57] Because the incidence of chronic disease increases with age, the health care and pension systems are expected to come under severe strain. In the mid-1980s, the government began to re-evaluate the relative burdens of government and the private sector in health care and pensions, and it established policies to control government costs in these programs.
The large share of elderly inflation-averse voters may also hinder the political attractiveness of pursuing higher inflation, consistent with the evidence that aging may lead to lower inflation. With the increasing older population and decreasing young population, 38% percent of the population will be people aged 65 and older by 2065. This concludes that Japan has the highest amount of public debt in the world because of the low fertility rates and aging population.[58] Japan's government has spent almost half of its tax revenue trying to recover from their debt. According to IMF, Japan has a 246.14 debt percentage of GDP, making it the highest public debt
The decline in working-aged cohorts may lead to a shrinking economy if productivity does not increase faster than the rate of Japan's decreasing workforce.
