(CNN) - U.S. Ambassador to Japan Caroline Kennedy stirred up controversy after expressing her "concern" over the slaughter of dolphins in Taiji, Japan.
Now, the Japanese government is firing back.
"Dolphin fishing is one of the traditional fishing forms of our country and is carried out appropriately in accordance with the law," said Chief Cabinet Secretary Yoshihide Suga.
Kennedy took to Twitter last week, saying she was "deeply concerned by the inhumaneness of drive hunt dolphin killing."
"We have fishermen in our community and they are exercising their fishing rights. We feel that we need to protect our residents against the criticisms," said Taiji Mayor Kazutaka Sangen.
Could Ambassador Kennedy's comment complicate relations between two vital allies?
