On the eve of U.S. President Barack Obama's historic visit to Hiroshima, residents and hibakusha on Thursday expressed support for calls to revise the U.S.-Japan Status of Forces Agreement following the suspected rape and murder of a 20-year-old Japanese woman in Okinawa Prefecture by a former marine.

They also said they would view Obama's visit as a success as long as he paid his respects to those who died in the Aug. 6, 1945, atomic bombing of the city.

There will be no formal apology for the bombing, which some hibakusha and their supporters have sought.
