Speaking to The Project from Japan on Monday, Gower said Brave Blossoms' fans also love the All Blacks.

All Blacks great Michael Jones said having so much support in Japan had been another point of difference.
"There's this great following," he said. "It's all over the world, but particularly here in Japan, they just adore and have such huge respect for the All Blacks."
