The 65-year-old's enthusiasm stems from the sterling display of the Indian Para athletes in the build-up to Tokyo that has already landed them 22 spots.
Singh, a former middle-distance runner, is confident the tally could swell to 35 by June, when the qualification period for most Paralympic sports closes.
Archery, athletics, badminton and shooting are the sports where India could gain 13 more slots in Tokyo, according to Singh.
He also marked out India's gold medal hopes - Sandeep Chaudhary (javelin F44), Sundar Singh Gurjar (javelin F46), archer Harvinder Singh (men's recurve open) and badminton player Pramod Bhagat (SL 3).
"We could also get a gold in either high jump or club throw event," he added.
These numbers are paltry compared to China's haul (239 medals, including 107 gold) at the Rio 2016 Paralympics. But for a country where Para sports and Para athletes have struggled to get national attention in the past, it is a big leap.
The turning point came in Rio, where the 19-member Indian Paralympic contingent fetched two golds, one silver and a bronze, to upstage the one silver and one bronze bagged by the 117-member Indian contingent at the Olympics.
Before 2016, India's best display at the Paralympics was in 1984 where they claimed four medals, two silver and two bronze.
Singh said the biggest change for Indian para-sports since Rio has been the rise in awareness levels about the para athletes in the country. The Paralympic Committee of India have had its hands full as it witnessed a significant rise in the number of Para athletes turning up for national and state-level events.
