TOKYO (Reuters) - Japan marked the somber nine-year anniversary of devastating natural disasters and a nuclear accident on Wednesday as official commemorations and vigils were canceled because of fears over the spread of the coronavirus.

The March 11, 2011, earthquake and tsunami triggered the worst nuclear accident since Chernobyl at Tokyo Electric Power Co's 9501.T Fukushima Daiichi plant, 220 kilometers (130 miles) northeast of Tokyo.

The natural disasters and meltdowns at the Fukushima plant forced hundreds of thousands of residents to flee their homes.

Prime Minister Shinzo Abe and other government officials attended a small memorial ceremony and observed a moment of silence on Wednesday, sitting in chairs spaced a few feet apart.

In his speech, Abe apologized for not holding an official memorial for the anniversary, saying it was a necessary step to contain the spread of the respiratory disease.

Abe also lauded the reconstruction of Japan’s disaster-struck region and said he hoped the Tokyo Olympics would be a chance for the country to showcase its recovery efforts.

“I think there were other ways to handle (the memorial),” said Natsumi Hoshi, a 42-year old Tokyo resident, who was among a group of around a hundred people gathered in a city park to lay flowers.

“I think people are still hurting,” he said.

Despite the many signs of recovery in Japan’s northeast, some residents are still unable to live in the areas closest to the Fukushima plant. Radiation levels in such areas remain high despite repeated decontamination efforts.

“I think the memory (of the disaster) is fading away,” said Masahiko Sano, a 47-year old company owner, who also joined the event at the park.

The government called off a memorial event that was scheduled for Wednesday as Japan sought to contain a widening outbreak of the coronavirus. The country has closed schools, theme parks and zoos, as part of its wider effort to scale back public events and mass gatherings to slow the transmission of the virus.

Japan has nearly 1,300 cases, including about 700 from the Diamond Princess cruise ship that was quarantined near Tokyo last month.

With every new spike in the figures, speculation has grown that the Tokyo 2020 Games, which are due to open on July 24, could be canceled, delayed, or held without spectators like many pre-Olympic qualifiers and other unrelated sports events in recent weeks.

The virus has infected more than 117,000 people and killed over 4,000 globally.
