Abstract
Hashima Island, now ruined, is an artificial reclaimed offshore island where coal mining industry flourished from the last of 19th Century to 20th Century. Having extreme dense population (over 1400 persons/ha during its peak), middle rise buildings are densely distributed on the steep rocky mountain in the middle of the island. Through its history, Hashma experienced several severe typhoons and resulted to show the form of protection and buildings turned away from the wind and ocean. This paper aims to verify the effects of the form of protection against typhoon in Hashima using CFD. Typhoon is represented as extreme wind speed from eight directions and the differences of climates in several places between buildings are described.
