Self-Defense Forces personnel opened a makeshift clinic in central Java on Saturday to treat victims of the May 27 killer quake.

The clinic, equipped with beds and other medical supplies, opened in front of the town hall in Bantul, in the Gunung Kidul area of the Yogyakarta Special Region.

SDF medical staff treated about 40 patients Friday from inside the town hall.

Ahead of the clinic's opening, a ceremony was held with the participation of some 100 local residents.

"We hope to be of assistance to you," Col. Sakae Ueno, the team's leader, said. "We hope you will make good use of this facility."

About 50 SDF medical personnel are currently in the area to provide relief in the aftermath of the quake, which has left more than 6,000 dead and thousands injured.

Japan has decided to send another 100 troops, including more medical staff, to provide additional support. They were scheduled to leave Japan in two batches Sunday and Monday.
