Is Saipan far from Japan? Does the nuclear leak in Japan have an impact on Saipan? If you want to go next month, ask urgently! ! ! ! Thank you all ~

I'm going to Saipan on the 1st-5th of next month ~ ~ I heard that the current wind direction is blowing in the Pacific Ocean. If Saipan is 2km away from Japan, it's the same distance as Japan from Shanghai ~ ~ ~ But the geography is just the opposite ~ ~ ~ I'm also worried about it because of the wind ~ ~ But think about it, life and death are rich in the sky ~ ~ ~ and it's a shame to be scared ~ ~ instead of being scared.
