Grammar/reference books/dictionaries
All good textbooks should introduce grammar in a systematic way and often provide supplementary materials for additional practice. For example, the popular Mina no Nihongo series have 2 supplementary Bunkei Renshuu Choo at elementary level. However, often students at an intermediate or advanced level of Japanese want to do a comprehensive review of grammar that the textbooks cannot supply. One way of doing this is to work through texts that prepare students for the grammar section of the Japanese Language Proficiency Test (JLPT). Any bookshop stocking English titles in Japan will have a good selection of these books. There are also a number of websites giving lists of the grammar patterns designated for each level such as http://www.jgram.org/
Another way to tackle comprehensive grammar review is to use one of the 4 texts introduced in Texts for Comprehensive Grammar Review below.
