Abstract

This article aims to help learners wishing to work in Japanese machinery and automobile design and manufacturing industries learn vocabulary effectively, and to enhance their work efficiency as well as enhance their Japanese employment capacity. The five-year history of the Japanese Mechanical Design Engineer’s Examination was used as analysis data, and the analysis was limited to nouns. A ratio of words in the upper 25th, 50th, 75th, and 100th positions is investigated by each word type. They also examined the consistency of the analyzed words with the “Basic Bictionary Survey for Japanese Language Education,” which is a survey data of the National Institute of Japanese Language. The results analyzed are as follows: First, the total number of nouns analyzed was 9,276 and the number of different words was 1,622; in the word classification, 65.4% Chinese words, 14.5% foreign words, 12.1% Japanese words, and 8.0% mixed words. Second, by examining the coverage of words by word type, it is confirmed that systematic vocabulary learning is necessary. Thirdly, words within the top 100 of each word category were presented, and many words related to machine design were confirmed except for the basic vocabulary presented by the National Institute of Japanese Language. Fourthly, it was confirmed that the degree of conformity with the basic vocabulary in foreign languages was low. This can be said to indicate that foreign words have many technical terms in the mechanical design field.
