Yes they were. Asians were subject to segregational practices in many cities. I wrote a bit about this topic previously here, but am always happy to add on to it or have more of a discussion on the topic. Filipinos, for example, were prominent targets of attacks by white people. This was often rooted in white men feeling threatened by Filipino masculinity; it manifested in arresting or even attacking or shooting Filipinos who were seen with white women during periods where anti-miscegenation laws were in place, as well as the invention of stereotypes about Asian men that are still widely believed today. In general, Filipinos were seen as less civilized than whites.
