I will go Osaka Japan in coming months! This is the question I also concern but as no much other place better than for my little child so Japan should still better choice. Also many HK BB and parent also still continues to go this place and even HKSAR government still no signal for Japan as disaster place.
What if the radioactive substance in food or drinks absorbed and combined with bone, or stay in thyroid or whatever organs?? The impact to babies and kids is definitely much worse to adults. Why expose babies and kids to unnecessary risk?
We used to visit Japan frequently before 311. Spring trips for Sakura, Autumn trips for red leaves, Kobe for beef and hokkaido for seafood... There are so many nice places in the world. Why not enjoy something different?
