In its announcement, Skype says:
Japan has also become a beloved destination for both tourism and business, and we’re excited for the potential benefit Skype Translator will bring to Japan, the community and our users.
In order to use it, click on the globe icon in your chat menu. If you’re using Windows 10, click the Skype translator button in the Preview app.
This isn’t just for Skype, though. Japanese is now available in all Microsoft Translation services.
Japanese is the tenth language in the Translator’s repertoire. The others are:
- Brazilian Portuguese
- Mandarin Chinese
According to the same post, Japanese was a tricky language to add. Skype hopes this will benefit native English speakers in particular, since Japanese is noted for being difficult for us to learn due to its different grammatical structure.
