The Trump administration has demanded that Japan nearly triple its payments for hosting U.S. troops to more than 3 trillion yen, or about $19 billion, over five years beginning in fiscal 2027.

Japanese and U.S. officials are negotiating a new five-year host-nation support agreement to replace the current deal worth 1.06 trillion yen through March 2027. The U.S. request would raise annual contributions from roughly 211 billion yen to around 600 billion yen.

Japan is considering a counteroffer of about 1.5 trillion yen over the same period, or roughly 300 billion yen annually. Sources close to the talks described the full U.S. figure as difficult to accept while noting room for compromise around the lower amount.

The new package is expected to cover utilities, Japanese civilian staff salaries at U.S. bases, facility maintenance, and new investments to improve the resilience of American military installations against potential attacks. Annual spending on such hardening measures could exceed 300 billion yen.

Bilateral negotiations intensified in Tokyo over the summer, with another round of talks possible as early as next week. Both governments aim to finalize an agreement before the end of the year.

This marks the latest round of cost-sharing discussions under the long-standing U.S.-Japan security alliance. During the first Trump term, Washington also sought significantly higher contributions from Tokyo.
