Can Florida residents get divorced in Japan, if they were married there?

My husband and I are both Florida residents and were married in Japan. We haven't been married long, only 10 months as of June 1st. But Florida requires one of us to be in Florida for at least 6 months before the divorce is filed for. Can my husband file for it in Japan where he is currently stationed? Or does it have to be filed in Florida to be valid?
