The Lower House on Thursday adopted a resolution urging the government to reduce the burden on Okinawa in hosting the bulk of U.S. forces in the country, in a move that comes ahead of the 50th anniversary of the prefecture's reversion to Japanese rule.

The resolution was adopted at a time when defense experts fear for the security of the base-hosting prefecture amid increasing challenges facing the Japan-U.S. alliance in light of situations such as cross-strait tensions between Taiwan and China and the ongoing Ukraine war.

The House of Representatives also called on the government to make utmost efforts to turn Okinawa into a stronghold for global peace and stability.
