How to Wrap the Japanese Text in the WordML?

Hi,

I am having a requirement  where I need to display the Japanese Text in WordML. I am able to display the Japanese text using the wordml and opening the document in microsoft word 2013  but the text is not wrapping to next lines as the Japanese text is long in length .

Can anyone suggest the solution for wrapping the Japanese text in WordML.

Thanks in Advance!!!

Thanks.
