More than 3,000 people gathered at Hibiya Park, about 10 minutes walking distance from the headquarters of Tokyo Electric Power Company in Tokyo on Monday to hold a minute's silence commemorating the victims of the tsunami, earthquake and nuclear disaster that struck Japan two years ago.

At 1446 local time , people, young and old, bowed their heads in respect for the dead.

The earthquake and tsunami killed more than 15,000 people. Several thousand are still unaccounted for.

The nuclear meltdown at Tokyo Electric Power's (Tepco) Fukushima Daiichi plant forced 160,000 people from their homes.

Many of them will never return.

Flags at the parliament building and prime minister's residence were flown at half-mast.

The Fukushima Daiichi plant has been brought into a stable state, but decommissioning its damaged reactors will take decades and cost billions of dollars. Many of the thousands who fled will never be able to return.
