Investors are raising concerns that Japan’s logjam of annual general meetings on the same day will limit shareholder engagement, posing an obstacle for corporate governance.

Almost 60% of companies will hold meetings this month, among which 30% will host on June 27, according to the Japan Exchange Group.

Blue-chip names with heavy weightings on the benchmark Topix — such as Nintendo, Sumitomo Mitsui Financial Group and Mitsui Fudosan — will report on that day.
