are fewer people? (ex. parties, shopping, etc.) Why?

Population Density in Japan:
Life in a Crowded Country
Background Information:
A. Japan occupies an archipelago,
or chain of islands
- 4 large islands and 3,900
smaller islands
B. Japan enjoys a temperate climate
- Heavy snowfall is limited to
high elevations & the far north
C. A chain of volcanic mountains
forms the backbone of Japan
- Mt. Fuji towers over Tokyo,
the world’s most populous city
D. Continued plate movement
leads to frequent tremors
- Undersea earthquakes can
trigger tsunamis
E. Only about 1/8 of Japan is
arable land. The rest is too steep.
- About 80% of the population
lives on limited flat land near
the coast.
How population density
affects transportation.
A. Public transportation
- The average commute time in
Tokyo is an hour and a half each day
- The Japanese have developed
an efficient public transit system
- Crowded underground subways
- Bullet trains travel between
cities at up to 180 mph
B. Private cars and parking problems
- Car ownership has increased, so
traffic congestion is a part of daily life
- Residents of Tokyo cannot own
a car unless they can prove they
have a place to park it
- The use of computer-controlled
parking lots has developed,
stacking cars in narrow slots
How population density
affects housing.
A. From the country to the city
- Because flat land for building is
scarce, housing can be expensive.
- Most homes in Japan are far
smaller than those in the U.S.
- Extended families used to live
together in rural areas
- Education & jobs = urbanization
B. Making the most of limited space
- The Japanese have developed
clever ways to use space wisely
- Many homes don’t have
separate bedrooms, only futons
- Household appliances shrunk
- Capsule hotels
- Cremation instead of burial
How population density
affects land use.
A. Building up and down
- The Japanese have found better
ways to use the land that is available
- Skyscrapers use earthquakeresistant construction techniques
in order to build higher
- Underground shopping centers,
restaurants, parks, museums,
and even a zoo
B. Creating new land
- New land has been created by
filling in shallow wetlands with dirt
- Destroys coastal wildlife
habitats & can be unstable to
earthquakes
- Cut rice terraces into hillsides
- Floating airport?
How population density
affects health.
A. Pollution problems
- Japan’s crowded cities have
created pollution issues
- Limited space for garbage,
sewage, & waste-water disposal
- Emissions from factories & cars
- Despite these problems, Japan
mostly remains extremely clean
B. Long lives
- The Japanese enjoy one of the
highest life expectancies in the world
- Sick people often wear face
masks to avoid spreading the
disease
- Japan has some of the strictest
environmental laws in the world
