A seismic wavefield means seismic waves propagating in a 3D medium. The method was constructed with the goal of adequately treating seismic surface waves trapped by a deep (several kilometers) underground structure in a soil\u2013building interaction system. Surface waves play an important role in a soft sediment where the amplitudes increase strongly. In the new method, very soft soils are substituted for the water volume so that only solid material is treated, and wave propagation is controlled according to wave types in the very soft soils that replace the water volume. The method is applied to the reclaimed zone of Tokyo Bay to explore the effects of the water volume on soil and building responses. The method seems to work fairly well, showing that the soil responses become more variable and the building responses get larger because of the water volume.<\/p>\n<figure id=\"attachment_1965\" aria-describedby=\"caption-attachment-1965\" style=\"width: 300px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-1965 size-medium\" src=\"http:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-300x231.jpg\" alt=\"\" width=\"300\" height=\"231\" srcset=\"https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-300x231.jpg 300w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-768x591.jpg 768w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-1024x788.jpg 1024w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-1200x924.jpg 1200w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842-500x385.jpg 500w, https:\/\/www.eri.u-tokyo.ac.jp\/en\/wp-content\/uploads\/sites\/2\/2018\/05\/35e8897390032c356a9097afc2b21842.jpg 1700w\" sizes=\"(max-width: 300px) 85vw, 300px\" \/><\/a><figcaption id=\"caption-attachment-1965\" class=\"wp-caption-text\">Fig. 1.
