In 1900, Masaki Tanaka left his Kumamoto, Kyushu home where his family owned an asbestos mine and timber business. He was the oldest son born in 1874 with 2 younger sisters and brother. Masaki boarded at a school up to the 8th grade, which would be considered highly educated in 1800's Japan. Why he emigrated to America is unknown.
At age 26, Masaki arrived first in Hawaii and later entered the U.S. via Tacoma, WA. In San Francisco, he met friends and moved south to Los Angeles where Masaki worked on road construction leading up to Mt. Wilson Observatory. Eventually, Masaki and a partner went into a Little Tokyo boarding hotel business which later failed. By 1911, he had shifted to farming in Arcadia, CA with other Kumamoto immigrants and also a ranch near a South Pasadena railroad station.
Masaki was introduced to Kaori, 14 years his junior, by her uncle, a Hawaii road contractor. In 1911, Kaori arrived as picture bride via Tacoma, WA, unhappy that she was "tricked into it." As children entered her life, she felt more content.
