[Machine Translation] Two editions of the JLPT Official Question Book have been published so far for the Japanese-Language Proficiency Test revised in 2010. The "JLPT Official Question Book" (published in 2012) and "JLPT Official Question Book 2" (published in 2018) contain the equivalent number of questions for each level of the JLPT from the actual test questions that have appeared since the 2010 revision.
