An earthquake fault under a nuclear plant in western Japan is "highly likely" active, meaning the two-reactor facility will probably be closed permanently, a panel of experts reported Monday. The draft report on the Tsuruga generating station, in Fukui prefecture, was commissioned by the country's Nuclear Regulation Authority. The panel discovered in December that Unit 2 sits atop a "crush zone" of small rocks and sediment that could move with a major fault, the Urazoko, which lies just 600 to 1,000 feet from the reactors. "If new knowledge is obtained, the judgment could be reviewed. However, at least at this point, the fault at the plant site is highly likely an active fault that needs to be considered in terms of seismic design," the report said, according toThe Japan Times. A fault is defined as being active if it has moved within the past 120,000 to 130,000 years, though regulators are planning to extend that back to 400,000 years. Last week, the NRA tightened a safety "guideline" by expressly forbidding the industry from putting reactors or cooling equipment on active faults.

What kind of moron builds a nuke over a fault line?
The whole country is in the red shaded area on this map, which is identified as the Pacific Ring of Fire:

Isn't the whole country on a fault line? But seriously, let's get that one closed
So, regarding your "but seriously..." statement, it's not that far off. Japan has so many fault lines that it's probably hard to find locations that are not within some distance of a fault line.
The Pacific Ring of Fire, or just Ring of Fire for short, is an area where a large number of earthquakes and volcanic eruptions occur in the basin of the Pacific Ocean. In a 40,000 km (25,000 mi) horseshoe shape, it is associated with a nearly continuous series of oceanic trenches, volcanic arcs, and volcanic belts and/or plate movements. The Ring of Fire has 452 volcanoes and is home to over 75% of the world's active and dormant volcanoes...
About 90% of the world's earthquakes and 81% of the world's largest earthquakes occur along the Ring of Fire.
I suppose if there's no safe place to build reactors, then perhaps don't build any? Burn coal instead perhaps? I'm not saying that's definitely the case...there may be some places in Japan that are relatively safe, but it's probably a challenge to find such sites.

As already mentioned, the whole of Japan is seismically active. Where would you have them build reactors?
