This paper reports on a case study of how Brazilian learners of Japanese learn Japanese word level prosody. Recordings of nouns and verbs with 2 and 3 morae by two advanced level Brazilian learners were analyzed. The results indicated that the learners most likely use interlanguage to realize Japanese word pitch patterns. The learners showed the following tendencies which cannot be interpreted as resulting from native language interference. (1) Application of different pitch assignment rules to nouns and verbs respectively. (2) Tendency to give high pitch to the heavy syllables in CVCVN and CVNCV structures. (3) Tendency to give high pitch to the first two morae in CVN and CVRCV structures.
