This study investigates the tendency of the word order of Japanese adjectives. Japanese adjectives are the representative adjectival modifiers and they define the nature, condition and characteristics of the words that are defined. There were not many studies on the word order among Japanese adjectives; however, their natural and general word order exists in case that the plural adjectives are used in the sentence. This study reveals the existence of a tendency in word order such as the adjectives representing the amount, the adjectives representing the old and new and the short- and long-term period and the adjectives representing the evaluation (judgment) by means of focusing on the word order among Japanese adjectives. Meanwhile, the adjectives representing the small and large, color and shape are not likely to have their word order. In short, this study suggests the following word order: amount〉time (old and new, long-term and short-term)〉small and large, color, shape〉evaluation> main noun.
