Kolisi, as South Africa's first black captain, knows delivering another World Cup in Japan could have a similar boost back home.
Kolisi could also join the 1995 Bok captain Francois Pienaar to make history lifting the Webb Ellis Cup.
Three years after he snuck into a pub to watch the 2007 final, Kolisi was a Junior Springbok.
The excitement over the final between England their soon-to-be decided opposition was rising, and ticket sales were mirroring that. "I just want to thank everyone for their support from back in South Africa; it's been special and I urge everyone to keep supporting us". In the second half, South Africa managed to score a try but Wales returned with their own try moments later bringing the score to a tie at 16-16.
With seven black players in the starting team for the semi-final, his side is the most representative to have run out at a World Cup, and the captain said that the Boks were playing for everyone in South Africa. Williams is patron of Wales Rugby Union while Harry succeeded the Queen as patron of the England team in 2017.
A spokesman said: "As it stands, we only have a tiny number of seats left on our twice-daily flights to the Japanese capital this coming week, but we're exploring a number of options to help fans get there".
Johnson might not be immediately focused on the Rugby World Cup as he attempts to have his Brexit deal pushed through before the 1 November deadline which is just a day before the final.
The Springboks last lifted the Rugby World Cup in 2007 when they beat England in a tight final in Paris, only Frans Steyn is still in the set-up 12 years on.
For England their only triumph came in 2003 when a Jonny Wilkinson drop-goal gave the Roses an extra-time win over the Wallabies in Perth.
A pair of Category A tickets were being sold for £25,000 on the secondary ticketing site StubHub on Sunday, compared with their face value of £717 each. The match is scheduled to kick-off at 11:00 SAST and will be broadcast live on Supersport with commentary available on SABC Radio.
