I would think so, as Nagano prefecture doesn't have any ocean to it, It's smack in the middle of Honshu!

My worry is the earthquake in Niigata, where there are nuclear plants knowingly built on faulty lines and with poor safety and security record.

Hope everyone's okay.

Worth remembering Fukushima was damaged by a tsunami not an earthquake.

As long as they were not in Fukushima near reactor 4 I think its good news...

My worry is the earthquake in Niigata, where there are nuclear plants knowingly built on faulty lines and with poor safety and security record.

Just the one plant, but Kashiwazaki-Kariwa was the biggest in the world in terms of output until it was shut down after the Tohoku earthquake. And, as you say, it has a very poor safety record. I would have to admit to being very glad that I no longer live in Niigata, in that respect.

Worth remembering Fukushima was damaged by a tsunami not an earthquake.

I believe there is still some debate about this - I have a recollection of seeing a headline from a Japanese-language media story on Twitter recently that said that at least part of the damage was (or possibly was) caused by the quake, not the flooding by the tsunami.

I don't know what the risk of a tsunami on the Sea of Japan is, since it's a smaller body of water than the Pacific Ocean, but with all of Japan's nuclear plants using the sea as their ultimate heat sink (other countries also use lakes or even the air), a tsunami is a risk for all of them.

Not according to the report released by the gov't commission which investigated the cause of the disaster. They also called it a man made disaster.

Tsunami have happened in the Japan Sea but since more than 50% of the world's tsunami's are generated in the Pacific Ocean, a tsunami in the Japan Sea is less likely than on the Pacific side. But TEPCO and KEPCO are both increasing the size of their sea defenses.

It's all good. Only the northern part of Nagano was shaking. Nothing new in those parts.

Regarding earthquake caused damage, NHK reports today::

Fuel rod container at Onagawa plant found damaged

Japan's nuclear safety agency has ordered Tohoku Electric Power Company to check and report on whether the damage was caused by the massive earthquake on March 11th last year.

The utility recently used an underwater camera to inspect the 4.5-meter-high metal containers in a fuel rod storage pool.

It found a 2-centimeter-long, several-millimeter-wide chip on one of the containers. It also found more than 12 places on other containers where pieces were missing.

Such damage has never been reported at a nuclear plant in Japan.
