Location of japan
East Aisa
36.2° N 138.2° E
Population statistics
124 million
‘hyper-aged’ - >30% of citizens are over 65
median age is 48 - nearing post reproductive years
aging and declining pop
uneven distribution of pop - higher in the south
capital city is tokyo - 13 million people live there
literacy rate is 99%
highest average life expectancy in the world - 88 for women & 81 for men
Geographic features
made up of around 6800 islands
¾ is mountainous because of tectonic plate movement along pacific ridge
temp is temperate, varies from north to south
37,000 square kilometers, which is about 120th the size of Australia
What is causing the shrinking & aging population (population dynamics data)
current DTM stage: 5
peak pop was 148 million in 2010
pop pyramid went from: pyramid to coffin
BR: 6 per 1000 people
DR: 12 per 1000 people
TFR: 1.21
IMR: 1.50 (good healthcare)
LE: 84 yrs
pop growth rate: -0.4% (2024)
About the smaller workforce in Japan
Workforce has been declining since 1995
because of aging population
less people contributing to the economy
Social drivers for a smaller workforce
Social/cultural drivers
low birth rate - 6
high life expectancy - 84
work habits - 11% of employees work >60 hours per week (8 hours each day w/ no weekends)
family-based support for the elderly means less time at work, making money and contributing to the economy
Traditional gender roles - women leave the workforce once they get married and have children
What is the trend in the data
Aging and shrinking population
One issue the population faces becuse of shrinking & aging population
smaller work force, smaller domestic market, less women having children
Context for smaller work force
Employment-to-population ratio is 60.2% in 2024
minimum mandatory retirement age is 60
uneven old age dependency ratio
working-age population fell 13% (from 87.3 million in 1995 to 73.7 million in 2024)
low immigration - represent only about 2% of Japan's population (approximately 2.93 million people in 2020)
Only about 11% of Japan's land is arable
Context for smaller domestic market
smaller population directly results in a smaller domestic market and less demand for goods and services, negatively impacting the country's Gross Domestic Product (GDP)
Context for women having less children
Childbearing in Japan is strongly linked to marriage, but marriage rates are falling
average age of marriage for Japanese women has increased to 29.9 years. This results in fewer reproductive years to have children
Long working hours - averaging up to 60 hours per week for employees
11% working > 60 hours
More than 50% of women stop working after the birth of their first child
husbands contribution to household tasks never exceed 5.3 hours per week on average
husbands have estimated 1 hour of childcare contribution compared to 3 in the USA and Germany
what are the challenges faced because of the smaller work force, smaller domestic market, less women having children
WF -Increased Elderly Dependency Ratio - elderly dependency ratio increased rapidly
7 economically active individuals supporting each person over 65 in 1985
2.8 in 2010
projected to fall to 1.7 by 2035
less government revenue from taxation
Benefits for the aged account for about 70% of Japan's total social security expenditure
exceeds ¥2,200 billion annually and is expected to grow
proportion of the 0 to 14 age group has significantly reduced, almost by one-third between 1950 and 2020, to 12%
What’s a response to Increased Elderly Dependency Ratio
self-driving tractors using GNSS (geographic navigation satellite systems)
first automatic tractor was made in 2017
updated in 2020 with x-tractor (which uses AI)
11,000 units were sold in 2024
38% of tractors sold in 2024 are semi-automatic
costs between $160-$250 AUD NEW
operated with supervision
provides accurate plowing, seeding & fertilization
How has the Kubota tractors affected the environment
Environ Factors
reducing waste or runoff of fertilizers
how has the Kubota tractors affected the economy
Economic factors
significant investment - $160,000 and $250,000 Australian Dollars.
reduce the labor needed in the fields - lead to cost savings for farmers by lowering labor expenses
Improved Efficiency and Accuracy - X-Tractor model, updated in 2020, uses AI to achieve accuracy between 1-5 cm, leads to more efficient use of resources and potentially higher yields
how has the Kubota tractors affected the social
Social factors
Response to Aging Farmers - helps alleviate the physical demands of farming
average age of Japanese farmers increased from 51 years in 1980 to 65 years in 2020, with 70% of farmers aged 65 years and over in 2020
Effectiveness (SAFFEIT)
sustainability - could prevent eventual runoff, keeps waterways healthy
accessibility - expensive (160,000-250,000 AUD), able to be accessed on phone
flexibility - precise between 1-5 cm accuracy using AI
fairness - using a retrofitted tractor ($17,000 AUD)
effectiveness - uses GNSS/QZSS (quasi-zenith satellite system) to reduce labor shortages
incentives - the profit from the more precise harvesting
time - reduces travel time to operate vehicle
