I never said that the people up north don't need help; I have family and friends up there, and will be spending April and May helping people to rebuild.
What they don't need is a patronizing attitude. These people are tough, and they will overcome.
The reason that supplies aren't getting up to Sendai is not that there aren't any. The transportation network is broken, and fuel is in short supply.
Fukushima's got the double-problem of panic; there are hospitals 30km away from the plant that can't get supplies because the truck drivers are terrified that they'll get exposed to radiation, even though the equivalent dose of half a dental X-ray... if they spend the entire day.
Panic is the real problem here, and the rest of the world acting like the entire country has just been leveled by the fist of God is part of the problem.
I wouldn't be so frustrated if I didn't have to deal with daily phone calls from people back home asking whether or not I've grown a third head.
On the second bit, no. Religion works very differently here.
The temples and shrines play a vastly smaller role than churches do for Western religious groups, even in the countryside. There are no weekly gatherings, and most people don't identify with specific temples or shrines, at least not in any of the countryside I've spent time in.
Religion in Japan is national, not local.
You go to your local shrine for local festivals, and that's pretty much it. If you move, you go to a different one.
You've got a small shrine in your house for talking with your ancestors (called a kami-dana, or god-shelf), and people keep these to varying degrees, no matter where in the country they live.
Otherwise, social gatherings are defined by your school or work, or by whatever other organizations you might belong to. Youth groups, church football leagues, and all the other stuff you have in the US doesn't exist here.
So, no, they're not like agnostic christians. They're like Shinto-Buddhists, which refers not to the biggest sect (Jodo Shinshu), but to the religious blend that is most common in Japan (the Nichiren are also shinto-buddhists, for example).
