Japan and the United States are poised to agree on measures to keep upper limits intact when they renew a treaty on host-nation financial support for U.S. military facilities in Japan, Japanese government sources said Sunday.

The measures are designed to keep Japan's financial obligations almost unchanged, departing from the cost-setting method that led to higher burdens when the treaty was renewed twice in the past, the sources said.

They would address U.S. objections to reductions in host-nation support and calls by Japanese lawmakers for outlays to be scaled back after the current treaty expires next March.
