In Thursday's Paralympic action, Japanese swimmer Suzuki Takayuki has won the men's 100-meter freestyle.
It's Japan's first gold medal at the Games.
Suzuki was born without both legs and a right hand. He also has an impairment affecting the fingers on his left hand. He took up competitive swimming in high school and has now taken part in five straight Paralympic Games.
In Thursday's event, the 34-year-old was second after 50 meters, but took control in the closing stages to claim the gold with a Paralympic record.
This is Japan's first gold in two Paralympics. The team did not win a single event at the 2016 Rio Games.
In the men's 100-meter backstroke, Belarus's Ihar Boki won his second gold of the Games. The swimmer has a visual impairment. He won 6 events in Rio, the most at the Games.
And Anastasia Pagonis of the US won the women's 400-meter freestyle, setting a world record in the process. The 17-year-old is known for using her social media platforms to spread awareness about Paralympic sports and visual impairments.
Meanwhile, the Godfather of para equestrian has got off to a fast start in Tokyo. Britain's Lee Pearson won the dressage individual test event, adding yet another gold to his record tally.
Pearson was born with a condition affecting the flexibility of his joints. He has competed in six straight Paralympics, and has now claimed 12 golds, a record for Paralympic equestrian.
He won Thursday's event with a precise and dynamic showing.
Pearson is openly gay and has been a passionate campaigner for equal representation in sports throughout his career. He said after his victory the Paralympics are "about acceptance" and society should respect all sexualities and impairments.
Austria's Pepo Puch took home the silver. He competed in able-bodied events, including the 2004 Athens Olympics, before a spinal injury in 2008 left him with incomplete paraplegia.
But he returned to competition at the London Paralympics, and has picked up two golds since.
