I am also surprised that some of us want to go, no matter what. Of course, I can understand that you all are eager to finally go to Japan, but under the actual circumstances, there is no way we will be able to study or "enjoy" our life.
I agree with you that if the worst happens, it would be wiser (although disappointing) to stay home, but the "actual circumstances" on which we should base our judgement, are such as this:
-Major damage caused by the earthquake and following tsunami in the Tohoku area.
-Serious situation in the Fukushima Daiichi power plant. Serious, but it's nowhere near Chernobyl (which some sensationalist reports tend to compare it to, while it will probably end up as the Japanese Three Mile Island). Those are different reactors, evacuations started early and there is much more transparency regarding the whole incident.
-Electricity, gas, water, food and gasoline shortages in the Kanto area. Minor damages to buildings and roads, too. The public transport is not functioning properly - few lines are operating at their full capacity, several are cancelled.
-Rest of the country is functioning more or less normally, if under stress.
I don't know about your local media, but the reports on Polish TV are extremely sensationalist (they have finally learnt that Miyagi is not in Tokyo, I give them that), and CNN or BBC are not much better. The NHK World is doing a much better job. You can also watch the NHK emergency channel, if not for information (all done in Japanese), then to see that Japan is not drowned in chaos and panic. For information on the Fukushima situation, see the TEPCO website. (Can't post links, but they're googleable.) You might say it's all lies meant to contain panic and all Japanese are going to grow green scales all over their skin in a matter of days (like some people I know), but we all trusted Japanese authorities when we signed up for this scholarship, we shouldn't distrust them now.
Apart from those who were supposed to go to Tohoku, we actually should be able to study. It would be stressful and we'd have to put up with lots of inconveniences, but it was never meant to be a relaxing trip to Japan sponsored by the Monkasho in the first place. It's common knowledge that Japan is seismically active and has many nuclear reactors. I decided to study there knowing that things like the Friday earthquake and the following events might happen any moment.
