TOKYO (Reuters) -Japan's top currency diplomat, Atsushi Mimura, said on Wednesday that he is concerned about the surging valuation of the stock market powered by the AI boom.

There are concerns "whether or not the current stock market situation might be a bit too rapid and going too far," Mimura said, speaking at a Bloomberg event in Tokyo.
