Japan's total US energy investment commitment under the March 2026 White House deal is $73 billion: $40 billion for BWRX-300 SMRs in Tennessee and Alabama plus $33 billion in natural gas power plants in Pennsylvania and Texas. This is part of the broader $550 billion US-Japan bilateral investment framework agreed under the Trump-Takaichi trade agreement. The energy package is the centrepiece of a landmark US-Japan economic partnership announced at a historic White House meeting.
