The issue discussed in this research includes learning new vocabularies by Japanese language learners who are competent and the relevance of vocabulary- learning strategy by Oxford (1990) to foreign language learners' current condition. This research aims to elaborate on the relevant vocabulary-learning strategy for foreign learners of the Japanese language. The research methodology is qualitative, with semi-structured interviews by adopting the questionnaire by Saengpakdeejit (2014). The vocabulary-learning strategy is classified based on the taxonomy of vocabulary learning strategy by Oxford (1990), Schmitt (1997), and Churches (2009). The result shows that Japanese language learners who are competent apply the vocabulary learning strategy, as Oxford (1990) stated. The dominant strategy used by the participants is a cognitive strategy, which allows new vocabularies to be stored in the participant's memory. Furthermore, information related to new vocabularies needs to be stored in the participant's memory using vocabularies. Besides, a competent Japanese language learner can use the learning resources, printed materials, and digital application to improve the vocabularies.

Introduction One of the most challenging tasks in learning a second language is vocabulary learning. Vocabularies have a crucial role since they cannot express their idea and understand what is stated by other people without adequate vocabulary. It is in line with the statement of Wilkins (1972); without grammar, very little can be conveyed, but without vocabulary, nothing can be conveyed. Since vocabularies are essential in learning any language, it requires a learning strategy. There are many strategies for learning vocabulary to be used by learners. The learners may apply a learning strategy different from each other and considered useful for learning new vocabularies (Goundar, 2015). Gerami & Baighlou (2011) performed an investigation from several researchers related to factors that affect the choice of a second language- learning strategy. They concluded that the influential factors are language fluency in learners, motivation, learning style, cultural background, gender, nationality, and language-learning context. Wang (2015) also stated that the use of second language- learning strategies is affected by internal factors (age, intelligence, personality, and
