Prime Minister Fumio Kishida sent a chill through local markets late last year with talk of introducing restrictions on share buybacks, but the head of the Tokyo Stock Exchange says investors have little to fear.

Hiromi Yamaji, the president of the exchange, said in an interview that Kishida was unlikely to consider blanket regulation on share repurchases as part of his goal to better distribute the fruits of economic growth.

"Kishida has a quite cautious stance on the uniform regulation of share buybacks, because he is giving consideration to each company’s individual circumstance and decisions,” Yamaji said. "I don’t think it is going to be an impact on capital markets.”
