Protesters on rubber boats hold up a banner saying "Do not come, Osprey", in reference to the arrival of MV-22 Osprey aircraft, in the sea in front of the US Marines' Iwakuni base in Iwakuni, Yamaguchi prefecture on July 23, 2012. The US military's Osprey aircraft arrived in Japan at Iwakuni as residents rallied against their deployment after recent crashes raised safety concerns.  The US military plans to fully deploy Osprey aircraft to Okinawa in October while the governor of the sub-tropical Japanese island chain has denounced the US plan because of safety concerns.
