But the Cardiff Blues flanker has warned his team not to take their opposition lightly as Warren Gatland’s side look to make three wins from three this November.
“It will be nice to be captain. I think there are 60,000 tickets sold. It will be a big occasion, as it is any time you get to play at Principality Stadium,” Jenkins said.
“The big focus for me, as it will be for everyone else, is performing as well as possible. That’s all that matters. It is a big game for lots of us and it’s something we are really looking forward to.
“There are always a few nerves. The bus journey in is probably the most nervous part. The atmosphere is great and it’s surreal to see everyone cheering.
“Tonga can be dangerous, especially if the game gets loose. When we played them in 2017 we drove them a lot.
“The weather conditions were terrible, but we managed the game quite well.
“We ground them down, ran them around, tired them out, and came through in the last 20 minutes. That could be what happens again.
“We’ve spoken about not getting carried away and not getting pulled into the type of game they want.”
Jenkins captained Wales against South Africa in Washington DC in June, but has never led his country on home turf.
The Cardiff Blues flanker will win his 10th cap against Tonga as one of 14 changes from the Wales team which ended a 10-year wait to beat Australia.
“I think playing too much is something we maybe have been guilty of in the last couple of years,” Jenkins said.
“When we play the tier two nations and make lots of changes, there are different combinations and it can be difficult. We try and do too much too early.
“We have spoken about sticking to our guns and it will be a good test for us.”
