Besides being only Chinese, the Japanese were another big part of Seattle’s population at the time. Trying to exclude themselves from the Chinese, they built themselves a home on Main street 4th avenue and 7 th avenue also known as Japantown or Nihonmachi. It flourished with its many hotels and communities, Japan soon made the largest minority population. Traces of Nihonmachi go back as far as 1891 when Dearborn street was once called Mikado street. Around 1940 when the Japanese population diminished, the eastern side of Nihonmachi was demolished to build Yesler Terrace.
