Okinawa Gov. Takeshi Onaga expressed disappointment Wednesday that the U.S. and Japanese leaders failed to show a willingness to respond to calls to revise a bilateral accord defining the handling of U.S. base personnel in Japan in the wake of the arrest of a civilian U.S. base worker over the death of a local woman.

"It is extremely regrettable that there was no mention of amending the Japan-U.S. Status of Forces Agreement," Onaga told reporters in Naha, referring to the press conference after the meeting Wednesday evening between Prime Minister Shinzo Abe and U.S. President Barack Obama.

Onaga said people in Okinawa "have been forced to bear the heavy burden of hosting the bases."
