Shobushi, whose real name was Kiyotaka Suetake, died on May 13, 2020 due to multiple organ failure caused by the novel coronavirus.
The 28-year-old was the first sumo wrestler to die from the pneumonia-causing virus.
He is also thought to be the first person in their 20s to die from the virus in Japan.
According to the JSA, Shobushi, who suffered from diabetes, recorded a fever of about 38 C on April 4. His Takadagawa stablemaster and others contacted hospitals and local health centers but were unable to find a facility able to take in the wrestler.
After coughing up blood, Shobushi was finally admitted to a university hospital on April 8 and transferred to a different facility the following day.
The Yamanashi Prefecture native became the first sumo wrestler to test positive for the virus on April 10. His condition worsened on April 19 and he was treated at an intensive care unit at a hospital in Tokyo.
Shobushi made his professional debut in 2007 out of the Takadagawa stable and reached the No. 11 rank in the sandanme division.
