Hendrik Tui revealed the Brighton crowd helped roar Japan to a “world changing” win over South Africa.

The No.8 admitted he was “buzzing” after the injury time 34-32 victory over the Springboks at Albion’s home on Saturday.

The stadium’s first taste of World Cup rugby was a momentous occasion as the underdogs pulled off one of the biggest – if not the biggest – upset in rugby union history.

Tui said: “I can’t believe it. We have helped to change history. From half-time we gained confidence, we spoke in the dressing room that if we keep doing what we were doing, chopping them low and playing as a team, we could win.

“The boys rallied together and came away with a world changing win.”

Asked if he was aware of the crowd urging Japan to the last gasp win, he said: “The South Africa national anthem was very loud and the crowd seemed all behind them.

“But during the first half the crowd seemed to start supporting us and chanting for us so it was great.”

He added: “It’s the greatest game I’ve been involved in. It’s the World Cup on the greatest stage. I will go away from Brighton with very happy memories.”

South Africa coach Heyneke Meyer accepted the blame and did not look for excuses.

He said: “It was just not good enough. It was unacceptable and I take full responsibility.

“I am not going to blame the players. I picked the guys and still have confidence in them.”

Japan now play Scotland on Wednesday.

Yesterday, Samoa began their Group B campaign with a 25-16 victory over the USA in front of a crowd of 29,178 at the Brighton Community Stadium.
