The South African loose forward plays for Japan's Toyota Verblitz where Hansen has coaching links.
Du Toit said he was enjoying the experience of being coached by Hansen.
"Being part of the group where Steve is involved is a whole new experience for me. If you look at what he has achieved with the All Blacks, it goes without saying," he told South African newspaper Rapport.
"Something I noticed is that Steve is focused on a good team culture. The players should be happy. Another thing that got a lot of focus this week is individual skills.
"What has also changed is the balance of our training sessions. Where it has always been 100 percent temp, there is also more focus on clarity…what exactly is expected of each player," he said.
Du Toit has played only four Tests since being part of South Africa's 2019 Rugby World Cup success after several bouts of surgery.
But, he has returned to the game in Japan, where he recently produced a man-of-the-match performance for his side.
"I am finding my feet again," he said.
"As always, I still have a lot of work-on to become a better player. However, the Japanese league is very focused on attacking rugby. Because rugby here is still a fairly new thing among the spectators, they want to make it attractive to the public.
"It is different from what I was used to, and gives me the opportunity to adjust my game as I should," he said.
