I don’t know whether my calculations are valid (there’s many different kinds of radiation; some are more dangerous than others; also people absorb radiation at different rates; and there are no doubt many other complicating factors), but they are what I’ve been able to come up with. If anyone knows better (or I made some calculation or logical error) please let me know.
According to Idaho State University’s Radiation Information Network, average yearly exposure to radiation in the United States is around 3600 microsieverts. This includes radiation from natural sources like radon in the air, or cosmic radiation from the sun, as well as radiation from medical tests. This is equivalent to 360 millirems (e-1)/ 3.6 millisieverts (e-3)/ 0.36 rems ( e-4)/ 0.0036 Sieverts (e-6).
US regulations cap nuclear power plant workers’ yearly exposure at 50 millisieverts (that’s 50,000 microsieverts). (See Table 4 on the link).
Reuters reports that radiation exposure does not pose an elevated cancer risk until it reaches 100 millisieverts (that’s 100,000 microsieverts) a year. Even that level is disputed; the evidence that this amount does, in fact, increase cancer risk is far from conclusive, according to the Health Physics Society. (See the Power Point download on Radiation Effects).
Acute radiation sickness occurs in exposures of over .25 sieverts (that’s 250,000 microsieverts) in the course of a few hours or a day (See Table 2). In the US, rescue workers may be asked (on a volunteer basis) to expose themselves to up to twice this much radiation in "once in a lifetime" life-threatening rescue situations.
So, where do the levels stand from radiation emitted by the Fukushima Daiichi power plant? In 66 measurements from 34 locations in Fukushima prefecture on Thursday Friday, March 17, the median level of radiation measured was 3.7 microsieverts/hour. Even if these levels continued for a full year, this radiation dose does not come close to the threshold for elevated cancer risk (3.7 * 24 *365 = 32,412).
In Tokyo, March 17 readings show levels of radiation at .053 microsieverts/hour. That’s only about 1/70 of the median measurement in Fukushima, so really, Tokyo is fine, too.
However, there are some stations in Fukushima that posted measurements far above the median, and these are quite worrisome. Stations 31, 32, and 33 (all located just outside the 30km perimeter to the northwest of the plant) recorded an average reading of 104.34 microsieverts/hour. The nine measurements from these three stations are by far the highest recorded by any station. At this level, 40 days of exposure increases the risk of cancer (104.34*24*40=100166.4).
Radiation readings come from the Japanese government, and are available here.

For the past decade, the trend has been towards greater involvement by the national government in moral education. In 2002, the government funded the printing of a new national moral education textbook
Other laws and regulations further deepened national government involvement. In 2006, the Diet passed the new Fundamental Law of Education, which elevated moral education’s position in the curriculum as a whole. And new national curricular guidelines that come into effect in 2011 attempt to move the changes from the law books into the classroom .
As the LDP government’s 2007 Basic Policy for Economic and Fiscal Reform makes clear, many law and policy makers connected national moral education with
However, the DPJ’s electoral victory in August 2009 may mark the decline this view. During the DPJ-appointed Government Revitalization Unit’s hearings on budget issues, national expenditure on moral education came under fire. The committee recommended cutting these costs
In the greater scheme of things, the DPJ’s changes to moral education are modest. But these modest changes demonstrate the DPJ’s stance that the issues

In the hope of improving equity in education, the DPJ has made good on its campaign promise to eliminate tuition at public high schools. Until this year, public high schools
Funding for tuition remissions will come primarily from a progressive tax increase on families with high school-aged children . After the tax increase is factored in, a middleclass family with one child in high school and an income of $50,000-$60,000 can expect to be better off by $500-$600 a year, while families with annual incomes over $200,000 will only see a benefit of about $70 .
But will this actually increase equity in education? According to Ministry of Education statistics, 97% of children who complete middle school proceed to high school , and in 2008 only 2208 students left high school for financial reasons . So financial barriers to attending high school are not actually a widespread source of inequity in Japanese education, and a smaller program, targeted only at students financially unable to attend high school at all, would have been a more efficient use of these funds.
A more serious issue is the link between students’ wealth and the quality of the high school education they receive. Students in the public school system attend neighborhood schools during elementary and middle school, but for high school, students compete for slots in high-quality public high schools. Although middle school tuition is fully funded by the government, parents of children in the public school system spend an average of $3000 per year per child on supplemental tutoring and classes during the middle school years to bolster their children’s chances of earning a place in a top high school . Students with the resources to get outside education are more likely to get good grades  and have an obvious advantage when it comes to placement in a top-notch public high school, which in turn affects their competitiveness in college admissions and the job market. To seriously address inequity in education, the government should pay out more to families earlier in their children’s educational careers, even at the expense of reducing the subsidies for high school education.
*Even though tuition has been eliminated at public high schools, attendance is not completely free of charge. The average cost to parents of sending a student to high school is still around $2400 per year; this figure includes non-tuition school fees, books and supplies, after-school activities, fieldtrips, and commuting expenses .

Ichiro Ozawa, the DPJ’s Secretary General, has strongly pushed a proposal that would grant local suffrage to the over 900,000 foreigners with permanent residency status . After the DPJ took power in August 2009, it seemed briefly that, with his support,
Ironically, it may have been Mindan’s crucial support for voting rights that has helped solidify the opposition to Ozawa’s proposal. Opponents’ most urgent criticism is that foreigner suffrage would provide an avenue for foreign governments to influence internal affairs ; as Mindan receives operating funds from the South Korean government , its success in pushing the issue this far seems to prove the opponents’ point.
In actuality, this argument completely mischaracterizes Mindan’s accomplishment, and the implications of foreign suffrage. In the long term, Mindan’s movement would not primarily benefit
Furthermore, the permanent foreign resident community is increasingly diverse: Chinese, Brazilians and Filipinos all make up a growing share . Although Koreans historically have held a supermajority, in the future, no single nationality will dominate
There are plenty of legitimate arguments for and against foreigner voting rights, but there is no evidence to support that interference by foreign governments is one of them. Hopefully proponents will debunk this baseless criticism, and voters and lawmakers will consider the proposal on its actual merits and demerits, not on ill-reasoned paranoia.
* Around 40 countries allow some form of non-citizen suffrage. EU member nations permit foreign residents who hold citizenship in another EU country to vote in local elections; a smaller number of countries, including Korea, Venezuela, and Belgium grant local voting rights to foreigners who have met a multi-year residency requirement and

In 2007, more than 1 in 20 marriages
Japanese men may be marrying foreign women because they have difficulties finding suitable Japanese partners. The average age of a Japanese man embarking on an international marriage is 43, compared to 31 for a Japanese man marrying a Japanese woman . This suggests that marrying a foreign woman is not men’s first choice, but as men age, they become more willing to search further afield for a bride.
As for foreign wives, economic incentives undoubtedly lure many to
The nationalities of women marrying Japanese men shed some light on this issue. Chinese woman account for 37% of foreign brides, Filipina 29%, Korean 18%, Thai 5%, and Brazilian 1%.

Japan’s Industrial Trainee and Technical Internship Program brings 80,000 to 100,000 foreigners to Japan each year  to work for up to three years in industries such as agriculture, textiles, and food prep . Japanese immigration policy makes no general provision for unskilled foreign workers; technically, no visa category exists for unskilled labor. But by calling the participants “trainees” and “interns,” the program has created an ad hoc mechanism to bring these types of workers to
It is easy to see the program as a cynical creation of lawmakers eager to woo manufacturing and agricultural constituencies. Indeed, the record on this score is not good. Around 67% of participants come from mainland
However, lawmakers and bureaucrats did not sit idle while these criticisms came to light. The Ministry of Health, Labor, and Welfare, and the Ministry of Economy, Trade and Industry both investigated and recommended reforms. In response to this, in July 2009 the Diet overwhelmingly voted to strengthen legal protection for trainees and interns and increase government oversight of employers . For example, employers must now provide trainees with written contracts in their native languages, which are inspected by immigration officials. Trainees will be informed of their legal rights and obligations, and JITCO employees will inspect each place of employment once a month. The new regulations come into effect in one year .
These actions will certainly require a deeper investment of both government and employer resources. Even if the program is really a handout to crucial political constituencies, this heartening commitment demonstrates that the government is not willing to hand over cheap labor regardless of the human costs.
