“…Several relevant previous studies have explored speech acts including criticism speech acts in cross-cultural contexts involving Japanese, Indonesian and regional languages in Indonesia. These studies cover various aspects, such as studies of directive speech act strategies in Japanese and Minangkabau focusing on politeness (Putri & Haristiani, 2021), Japanese and Javanese greeting terms (Rahayu et al, 2023), refusal speech acts in the context of politeness between native Japanese speakers and Japanese Indonesian language learners (Nurjaleka, 2019), interlanguage apology and complaint speech acts in Japanese and English (Tamanaha, 2003), expressions of reference used in Malay and Japanese speech acts (Okubo et al, 2022), speech acts from a referential perspective in German and Japanese (Matoba, 1996), and a study of Japanese language apology speech acts by Javanese and Sundanese Japanese learners (Savana & Meisa, 2021).
