What was the reason that thousands of japanese americans voluntarily joined the us military during world war ii?

To show loyalty to the U.S., gain upward mobility and/or Citizenship

Explanation: During World War II, many Americans of Japanese descent volunteered to join the U.S. military. This was in spite of growing sentiments against them as well as internment of Japanese Americans in camps.

It was a way to show loyalty to the U.S. For some it was the only way to gain citizenship, as well as move up the social ranks as ethnic minority groups had limited rights. They were first rejected, with the exception of bilingual Japanese Americans who helped with translation and interrogation.
