This chapter first introduces law translation in 19th-century and post-war Japan, focusing on the purposes of law translation and the effect of translation on the development of Japanese legal language. It then shifts the focus to the current law translation project. Its background and aims are introduced, followed by a discussion on the law translation database system and some of the problems with translations contained in the system. Further, possible solutions to the problems are suggested, such as the use of a translation memory. In conclusion, the importance of the government’s commitment to the continuous effort to provide quality translation of Japanese laws is reiterated.
