The runner, Krystsina Tsimanouskaya, had posted a message to social media criticizing the way her team was managed.
Krystsina Tsimanouskaya said she hoped she could continue her running career but that safety was her immediate priority.
"The campaign was quite serious and that was a clear signal that her life would be in danger in Belarus," according to the Belarusian Sport Solidarity Foundation.
Krystsina Tsimanouskaya believes her life is in danger and will seek asylum in Tokyo, a group supporting the 24-year-old athlete said.
