Native English listeners' perception of Japanese phonemic length contrasts was investigated using a minimal-pair identification task with Japanese words that differed by the length of a vowel or consonant, e.g., "haken"-"hakken". Identification accuracy was found to be higher for listeners with Japanese exposure than for unexposed listeners, and higher after five days of perceptual identification training than before. Even though listeners were trained to identify words containing vowel length contrasts only, accuracy improved for other length contrasts also. However, accuracy was relatively poor when the contrasts occurred in certain positions within the target word. In sum, while training improved English listeners' perceptual ability, a significant gap remained before they reached native-like performance.
