The Indian paddlers have been in exceptional form throughout the competition, not dropping a single game en route to the gold medal match.
Veteran paddler Sharath Kamal was India's second singles competitor on the day and like his teammates, he too recorded a 3-0 win against Bangladesh's Md Rifat Sabbir.
Singapore, Australia, Malaysia and Wales are the four sides that have made it through to the semi-finals of the event.
The men in blue have had a positive start to their campaign, winning all of their matches without dropping a single game.
It was yet another straight victory for the women in blue who are yet to lose a single game so far.
In the second qualifying round, India were drawn against Fiji and once again, the women in blue recorded a 3-0 triumph.
The 38-year-old paddler believes the country has a good chance of bagging a medal in the mixed doubles category in Tokyo.
