Major H. Rahmat Shigeru Ono (September 26, 1918 – August 25, 2014) was a Japanese soldier who defected and sided with Indonesia.

When Japan was defeated by the Allies, Ono became one of the troops who refused to return to Japan and chose to join the Indonesian people to seize independence, they were known as the elite commandos of the Pasukan Gerilya Spesial[citation needed] (Special Guerrilla Force) under Untung Surapati's troops.

However, in 1952 when Ono was summoned by the Japanese Consul General in Surabaya, he managed to reconnect with his mother.

The story of his life is told in a book entitled Those Who Have Been Forgotten: Memoirs of Rahmat Shigeru Ono, Former Japanese Soldiers who took the Republican side by Eiichi Hayashi.

At the time, President Susilo Bambang Yudhoyono had asked him to be present at the Merdeka Palace to celebrate the Independence of the Republic of Indonesia.
