Thanks!

The government has been making efforts, such as trying to improve the training and certification of Japanese language teachers, making Japanese language ability a condition (or at least an advantage) for getting certain types of visas, and offering language support to immigrant children in public schools. They are also trying to promote the use of simplified Japanese—avoiding difficult vocabulary and indicating the readings of all kanji—in documents and services aimed at the general public, something that would help not only immigrants but also Japanese with lower literacy skills. I’m sure much more could be done, though.
