As a result of the recent murder of a 20-year-old woman in Okinawa, allegedly at the hands of a U.S. base worker and former marine, calls are once again growing for a revision to the U.S.-Japan Status of Forces Agreement, or SOFA.

On Tuesday, Aiko Shimajiri, the minister in charge of Okinawa's affairs, and other LDP lawmakers from the prefecture submitted a request to LDP Secretary-General Sadakazu Tanigaki calling for revision of the agreement.

Tanigaki reportedly told the group that "the party will make every effort" regarding the issue.
