Japan says it will send Patriot air defence missiles to the US after changing its arms export rules, in a significant shift away from its pacifist policies.
The move could free up the US to send its own stockpile to Ukraine.
Shortly after the government announced this change on Friday, the foreign ministry said it would ship Patriot missiles to the US to "further strengthen the Japan-US alliance".
It added that the missiles could only be sent to the US, and would require Japan's approval to be sent to a third country. Japan still bans the export of weapons to countries at war.
This could mean that Japan-made Patriot missiles may replenish the US' stockpile, while Washington sends US-made ones to Ukraine.
Tokyo is also considering exporting 155mm artillery shells to the UK as it makes them under licence from London-based BAE Systems, according to the Financial Times.
