Nearly half of the companies on the Tokyo Stock Exchange¡¯s prime section have responded to a call to disclose plans to improve capital efficiency, the bourse said on Monday, as it released for the first time a list of those who had complied.

The list, which did not include some of Japan¡¯s biggest and most influential companies such as Toyota Motor and SoftBank Group, marks the culmination of the bourse¡¯s push to nudge firms to improve governance and investor returns.

Some 40% of the 1,656 companies on the exchange¡¯s prime section have publicly disclosed plans, while another 9% are considering such measures, the bourse said.
