Population distribution

all primary and secondary regions of high population density lie on the coast; one-third of the population resides in and around Tokyo on the central plain (Kanto Plain)

Natural hazards

many dormant and some active volcanoes; about 1,500 seismic occurrences (mostly tremors but occasional severe earthquakes) every year; tsunamis; typhoons

volcanism: both Unzen (1,500 m) and Sakura-jima (1,117 m), 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; see note 2 under "Geography - note"

Geography - note

note 1: strategic location in northeast Asia; composed of four main islands (the "Home Islands") - from north: Hokkaido, Honshu (the largest, most populous, and site of Tokyo, the capital), Shikoku, and Kyushu  

note 2: a 2023 Geospatial Information Authority of Japan survey technically detected 100,000 islands and islets, but only the 14,125 islands with a circumference of at least 100 m (330 ft) were officially counted; only about 260 of the islands are inhabited

note 3: Japan annually records the most earthquakes in the world; it is one of the countries along the Ring of Fire, a belt of active volcanoes and earthquake epicenters bordering the Pacific Ocean; up to 90% of the world's earthquakes and some 75% of the world's volcanoes occur within the Ring of Fire
