In April 2017, the BJT Business Japanese Proficiency Test started to be conducted using a Computer Based Testing (CBT) system, and the structure of some of the questions in the test was changed. This Second Edition has been partially revised to reflect such changes. The book also provides practice of all the types of questions found in the BJT test, but in greater numbers than in the actual test.

The Question Analysis section, in which the type of question, degree of difficulty and hints on solving it are discussed, is provided not only in Japanese but also in English, Chinese, and Korean.
