The outline of the research history, magma genesis, edifice evolution, eruptive period, and scale of the volcanoes in Japan have been reviewed as follows: 1) Recently advanced researches on the mechanisin and process of magma genesis and reservoirs beneath the subduction zone studied petrologically and seismologically have been introduced. 2) The fact that stratovolcanoes in Japan have evolved through a difmite course has been found. 3) The total volume of the volcanoes in Japan is ca. 15,000 km3. 4) The life span in average of the stratovolcanoes is approximately 0.4-0.5Ma 5) Many stratovolcanoes have erupted in the individual periodicity, mainly in the periodicity of once every 102 years. 6) Andesite volcanoes have mostly erupted in the one cycle eruption series through a changing course as follows: phreatic-vulcanian-strombolian-vulcanian-phreatic eruptions.
