There are six total and as far as I know from press reports four have been damaged. I think Nos 1,3, and 4 have had hydrogen explosions damaging the buildings. All four have probably had partial meltdown or at least damage to some of the fuel. The state of the primary pressure vessels is unknown but from the figures of high activity water in the basements it does appear there may have been some damage (cracking) of at least one vessel. Nos 5 and 6 reactors have not been reported as far as I know. I suspect this may be because they had already been shutdown a while before the incident so had less decay heat to remove, but this is only a guess.
During the Fukushima Daiichi nuclear disaster in Japan, three of the reactors experienced hydrogen explosions. These explosions occurred in Reactors 1, 3, and 4.
Fukushima is not an event that happened, it is a place, a prefecture, or district, in Japan. There are two Fukushima nuclear power plants. The plant where the accident took place, Fukushima Daiichi, is located in Okuma, Fukushima, Japan.
It happened on March 11th, 2011 at 2:46 local time.
I think four of the six on site, but they have not all had the same problems. The explosions were actually in the reactor buildings, not inside the reactor pressure vessels, and these explosions were due to hydrogen accumulating and forming an explosive mixture with air

Some examples of nuclear disasters include the Chernobyl disaster in 1986 where a reactor at the Chernobyl Nuclear Power Plant in Ukraine exploded, releasing a significant amount of radioactive material. Another example is the Fukushima Daiichi nuclear disaster in 2011, where a series of equipment failures and a tsunami caused meltdowns at multiple reactors in the Fukushima Daiichi Nuclear Power Plant in Japan. These disasters have had long-lasting environmental and health impacts.

Yes. That's how the diesel generators were damaged at Fukushima Daiichi, leading to the current crises there. Note that the reactors themselves were not touched by the tsunami because of the containment structures in place.
Before the Fukushima Daiichi Disaster, there were 54 operational nuclear reactors in Japan. Three of those melted down, and one had problems that rendered it inoperable. The government has decided the other two reactors at Fukushima Daiichi cannot be restarted. Also, as other reactors have been shut down for maintenance or refueling, they have not been restarted, with the result that now, in early December 2011, only eight Japanese reactors remain in operation.
