Is nuclear radiation serious in Japan now? Consider whether to travel there.

I planned to travel to Japan a few days ago and did my homework. But after hearing a few news, our trip was cancelled immediately: 1 A friend went to Japan for his honeymoon and was warned not to have children for five years after returning home. Because the influence of nuclear radiation is potential and intangible, it may not be discovered for several years but it is afraid of a long-term potential crisis. The current unstable situation between China and Japan may have little impact on this kind of folk tourism and cultural exchange, but we are afraid of what will happen in such a tense situation. The Japanese have always been very clever. I saw some netizens saying that air tickets were discounted and so on. At present, I heard that some places in Japan grant visa-free access to China people. I think this purpose is not simple. So don't go to Japan at present, consider other countries. There are many interesting places in Asia ~
