US reportedly wants Japan to almost triple its budget for hosting US troops, Nikkei reports.

Host nation support negotiations between Washington and Tokyo recur on a multi-year cycle, and the opening ask is traditionally set well above the eventual settlement; past rounds have seen the US table demands several times the incumbent level before both sides converge on a more modest increase, often packaged with in-kind contributions rather than pure cash. The parallel worth holding in mind is the parallel negotiation with Seoul, where aggressive opening demands historically produced prolonged deadlock and temporary lapses in the agreement before compromise, which suggests the headline figure is a negotiating anchor rather than an outcome. The transmission channel is narrow: direct FX impact on USDJPY has tended to be negligible in previous rounds, while the more consistent read-through runs to Japanese defense-adjacent equities and to the broader question of whether Washington conditions alliance posture on fiscal transfers. The actors' form matters here, since this administration has treated burden-sharing as a transactional lever across multiple alliances simultaneously, so the Nikkei sourcing is worth noting as the Japanese side signalling resistance through the press, a standard tactic in these talks. Worth watching is whether the demand leaks through official channels or stays at the report stage, and the state of the concurrent Korean negotiation, which has tended to set the template for the Japanese round.
