Marriage of Kamejiro Miyashiro 1894 1960 and Matsue OR Matsu Kaneshiro 1894 1933

Looking for a marriage date/record for Kamejiro Miyashiro b. 4 Jun 1894 d. 7 Oct 1960 and Matsu or Matsue Kaneshiro b. 27 Jun 1894 d. 16 Jun 1933.
The first record I have of them married is the United States Federal 1920 Census, Hawaii Territory, Kauai, Koloa, District 0015. It says that Kamejiro was 25 and immigrated in 1910 and Matsue was 24 and immigrated in 1913. They were both born in Japan as were their parents. Their occupations were laborers on a sugar plantation.
