I want to go to Tokyo in August (about 4 days). Is it safe? Because there is still radiation in Japan, I am worried that it will do harm to my health. ..

According to the data given by the Japanese government, there are basically no radioactive substances in the air and water except Fukushima, the hardest hit area of nuclear leakage. Even so, many open-air vegetables and grains around Fukushima still contain radioactive substances, which makes them impossible to sell. This is a fact, so it is still free to travel to Kanto, Japan. Besides, you are only 16 years old, and radiation is particularly bad for young people. Generally speaking, it doesn't matter after 40.

As for many people who say that there are still many Japanese or foreigners in Japan, why? Actually, it's all forced by life. Aren't they scared? The fact is that the Japanese have no choice but to stay if they want to work, get a mortgage and live. As for international students, they have already started school, so they can't go back to Japan. I spent so much money to study abroad, and I can't help my parents without a degree, can I? Those who are coming to study abroad have paid a considerable intermediary fee, so they can only comfort themselves if they don't come.

At present, it is not clear how serious the harm of this nuclear leak is, and it will take some time to cause cancer or other consequences.
