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

volcanism: both Unzen (elev. 1,500 m, 4,621 ft) and Sakura-jima (elev. 1,117 m, 3,665 ft), which lies near the densely populated city of Kagoshima, have been deemed "Decade Volcanoes" by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; other notable historically active volcanoes include Asama, Honshu Island's most active volcano, Aso, Bandai, Fuji, Iwo-Jima, Kikai, Kirishima, Komaga-take, Oshima, Suwanosejima, Tokachi, Yake-dake, and Usu

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
