Total renewable water resources:
430 cu km (1999)
Freshwater withdrawal (domestic/industrial/agricultural):
total: 88.43 cu km/yr (20%/18%/62%) per capita: 690 cu m/yr (2000)
Natural hazards:
many dormant and some active volcanoes; about 1,500 seismic occurrences (mostly tremors) every year; tsunamis; typhoons
Environment - current issues:
air pollution from power plant emissions results in acid rain; acidification of lakes and reservoirs degrading water quality and threatening aquatic life; Japan is one of the largest consumers of fish and tropical timber, contributing to the depletion of these resources in Asia and elsewhere
