Japanese Prime Minister Yoshihide Suga sent an offering to the controversial Yasukuni Shrine for war dead to coincide with its autumn festival.
It's Suga's first such offering to the shrine since taking office last month.
Watchers note the Japanese PM technically worshipped the war dead by sending an offering without visiting in-person to avoid angering Seoul and Beijing.
It's also seen as following in the footsteps of former PM Shinzo Abe, who regularly sent offerings during his time in office.
The Yasukuni shrine's controversy lies in the fact thatit honors Japan's war dead, including 14 Class-A war criminals.
