The Games are now 12 days in and India has only two medals - the other from weightlifting champion Mirabai Chanu in the women's 49 kg category.
She won a silver, putting to rest the disappointment of the Rio Olympics in 2016 where she was knocked out after a freak injury.
The man & women's and men's hockey teams have been in good form, and their medal hopes are still alive.
Men's hockey team
India beat Great Britain in the Men's Olympic hockey 3-1 on Monday to earn a place in the semi-finals.
They will face Belgium in the last four. The India team are historically the most successful team in Olympics hockey history, but the last of their eight golds came back in 1980.
Women's hockey team
India broke out into celebrations as the women's hockey team created history on Monday by beating Australia 1-0. The team has entered the Olympic semi-finals for the first time in history after the Rani Rampal-led side took the lead in the 22nd minute and defended it fiercely.
To put this win into context - the country's best result was a fourth-place finish at the 1980 Olympics.
Women's boxing
Lovlina Borgohain has assured India of another medal - a bronze after she beat Chen Nien-chin of Chinese Taipei to enter the semi-finals.
In boxing, there is no third-place match. Both semifinalists are awarded bronze medals. But she could still get a gold or silver if she wins her semi-final bout on Wednesday against Busenaz Surmeneli of Turkey.
Javelin throw
The Indian javelin contingent is led by Neeraj Chopra who is expected to win a medal. He is the current national record holder with a throw of 88.07m at the Indian Grand Prix in March this year.
At the international stage, he has a best of 88.06m at the Asian Games in 2018.
Wrestling
The Indian wrestling squad will begin its Olympic campaign led by Bajrang Punia and Vinesh Phogat. Having suffered a freak injury during the Rio Olympics, Vinesh Phogat returned to India in a wheelchair and underwent surgery.
With three world championships to his name, Punia is the top contender from India in the 65kg men's category at his first Olympics.
Here are India's big misses, and remaining medal hopes in Tokyo.

The big misses for India's Olympic hopes
Shooting
India's 15-member shooting contingent was the favorite to bring back a big haul of medals but that did not go according to the plan. Manu Bhaker and Saurabh Chaudhary, favorites for a podium finish in the mixed 10m Air Pistol event, crashed out in the second qualification stage in Tokyo.
Bhaker, pegged as a certain medal prospect even before the Games started, failed to reach the finals in any of the three events she participated in. She had a pistol malfunction in the 10m women's Air Pistol event, leading to more pressure as she lost time.
In the men's 10m Air Pistol event Saurabh Chaudhary, world No.2 and Youth Olympic champion, qualified for the final but failed to finish in the top three positions.
