Son, who arrived in Bandung on Monday to join the Korea Republic U-23 squad, said he will use the coming days to familiarise with his teammates.
"I have to get friendly with other younger teammates," he said. "I'll approach them first and will give them some advice. It's my job to help my teammates to play their best game."
Son arrived in Bandung after playing in Tottenham's opening 2-1 English Premier League win over Newcastle United on Saturday.
"On my flight to Indonesia, I thought a lot about the Asian Games," Son said. "I feel more responsibility as a wild card member and I have to play a good game."
Son, 26, is one of the three wild card players for Korea Republic at the 2018 Asian Games Indonesia. The other two are Daegu FC goalkeeper Jo Hyeon-woo and Gamba Osaka striker Hwang Ui-jo.
The men's football competition at the Asian Games is an U-23 affair.
Korea Republic are in Group E with Bahrain, Malaysia and Kyrgyz Republic.
Although expected to progress to the Knockout Stage, Son cautioned against underestimating their challengers.
"Like we beat Germany at the FIFA World Cup, we could also lose to other Asian teams," he said. "Football is a sport in which 11 players compete. We need to stay focused."
Son scored two goals at the 2018 FIFA World Cup, including Korea Republic's second goal in their 2-0 win over Germany.
Korea Republic open their Asian Games campaign against Bahrain on Wednesday before facing Malaysia (August 17) and Kyrgyz Republic (August 20) to complete the group stage.
