Another card from Nazrin, who didn't want her full name used, said: "I want to thank you with all my heart for being a great example to the world showing love, kindness and true strength reflecting your character. I pray almighty alah continues to shower you with love and blessings".
There was also a card from Wong wishing him a happy birthday as Sato is turning 97 early January.
Sato said publicity was never his intention and he was thankful for the cards.
"Thank you for your very, very kind thoughts. I'm truly blessed that you have come into my life too, even if it's from a distance, you're still there," he said.
"There are many, many people. They think the same as we all do. We care for each other. We respect each other and we love each other and may it always be that way...bless you all. Thank you. My love to you all."
Sato, who was born to a Scottish mother and a Japanese father, said he joined the anti-racism march at Aotea Square because he was aware of racism and different religious beliefs growing up in west Australia.
He said people should be aware of racism and be more understanding. He said he'd love to visit a mosque in Pakuranga in east Auckland some day.
"As far as I'm concerned, we're all people living in one world, so why do we go like that? We are all brothers and sisters in a way. We don't have to all agree. One family doesn't all agree either."
