adding tag

We would like to translate English course into Japanses. 

Would it possible to add Javascript tag into the course site we created ( inside of html header tag) or add the tag in each specific site or directory?  we are thinking to use the following automate translation tools.
自動ページ登録機能の設定方法｜shutto翻訳>ご利用マニュアル｜shutto翻訳｜さぶみっと！ (submit.ne.jp)

Also can we add html coding or XML coding on rise 360?
