The 2011 Canadian movie
Memories Corner involves
a French-Canadian reporter who travels to post-earthquake Kobe and is assigned a French/Japanese interpreter. It's not *technically* a Japanese production, but it takes place in Japan and has a mostly Japanese cast so maybe it's still of interest to you. Most of the movie is actually either in French (since it's the language shared by Ada & her interpreter Akira) or English (the language shared by Ada and another Japanese man she meets). Here's the
link to the (spoiler-free) blurb I wrote about it on my tumblr blog.
