In 2011, the National Institute for Japanese Language and Linguistics launched a corpus compilation project with the aim of constructing a ten-billion-word Web corpus. The project was split into the following four sub-projects: page collection, linguistic annotation, release, and preservation. In the page collection stage, crawling began during the fourth quarter of 2012. We crawled 100 million URLs every three months as fixed-point observations. This paper presents the basic statistics of the crawled data and discusses possible theoretical and practical implications of these language resources.
