Burma Star veterans have a window epitaph at St John's Church to the servicemen who died in Britain's Far East war.
It is named after the battle of Kohima, the turning point in the fighting against the Japanese in Burma.
Norman Davies, who was a 22-year-old flight lieutenant in the Royal Air Force when he joined the Burma campaign, said the service offer the chance for him to remember the many friends he lost.
Dozens of veterans and their families attended the service
He said: "I thought the service was very moving. It brought back sad and happy memories.
"We fought together, suffered together and laughed together and it just continues.
"You inevitably thank God for the friends you lost. Lots of my friends were killed and it was just nice remember them."
Cardiff Burma Star Association Secretary Walter Burns, 82, was emotional when he was asked to share his memories of the campaign.
He said: "We don't talk a lot about it, we get choked up. A lot of them have gone now."
In Newport, members of the Royal British Legion gathered in Tredegar Park for a service attended by the Lord Lieutenant of Gwent, Simon Boyle.
On Saturday, around 500 veterans with 40 British Legion standard-bearers took part in a parade through Porthcawl.
