A Face-Threatening Acts (FTAs) is considered to be an act, including an utterance, that can damage a person's face. This study aims to identify FTAs unintentionally committed by tourism workers toward Japanese tourists. Drawing on a qualitative approach, this study involved 25 participants selected in purposive sampling, and interviews were conducted with five Japanese tourists and four tourism workers who were available during the research. Data were collected through observation and interviews. Records and field notes were also used to collect data. In addition, domain, taxonomy, componential, and cultural theme analyses were applied to analyze the data and consider the power, distance, range of imposition, and speech situation. The results show that tourism workers perform negative FTAs when addressing Japanese tourists and offering goods or services for sale. Specifically, tourism workers demonstrate speech that implies oppression, the absence of honorific "keigo," the use of titles not commonly addressed in Japanese culture in the same context, a failure to understand that Japanese tourists may want to enjoy the beach privately, and speech when making offers that invades the privacy of Japanese tourists. Linguistically, tourist workers are using correct local conventions, but this cultural context is improperly perceived.
