As a product of the ongoing collaborative research project "Exploring Variation in Contemporary Japanese: Multiple Approaches", we published a collection of research papers titled "Exploring Variation and Change in Contemporary Japanese" in October, 2013. This review gives a brief introduction to one of the papers, which deals with variation and change in the meaning of the compound verb himotoku (Aizawa 2013). The paper shows that the ongoing process of semantic change in himotoku has been elucidated by utilizing the results of nationwide surveys in combination with large-scale corpora, thus providing a good example of "multiple approaches to linguistic dynamics".
