This article documents the heritage-language (HL) literacy practices of three Japanese American families residing in a predominantly Anglo and Latino community. Through interviews and observations, this study investigates Japanese children's HL-literacy practices, parental attitudes toward HL literacy, and challenges in HL-literacy development in a setting with minimal access to other HL speakers and resources. The data show that Japanese-literacy practices differed in each family, reflecting the situated nature of literacy and each family's unique needs for literacy. By providing exposure to varied forms of literacy texts and practices, the parents were instrumental in supporting their children's Japanese-literacy skills. Japanese literacy gave the children a strong foundation upon which to build their HL, supported familial relations, and also created channels of communication among family members. Although the parents possessed a focused commitment to achieve native-like HL literacy skills for their children, they were skeptical that their children would be able to reach this goal. The lack of external support, such as HL-speaking peers, HL schools, and accessible information about pedagogical strategies and resources, was perceived as a barrier to their efforts in helping their children sustain a high level of interest in HL-literacy practices.
