After the resignation of Tokyo Olympics chief Yoshiro Mori put the spotlight back onto gender politics in Japan’s circles of power, one software developer in the country has issued an apology for the composition of its board.

"We would like to apologize for failing to make a diverse workplace — by which we mean our board of directors. It’s three middle-aged men,” read the statement by Cybozu Inc., carried as a full-page advertisement in the Nikkei newspaper. "It’s truly embarrassing.”

Two of the three are the co-founders of the company, both former employees of what is now Panasonic Corp. The third, Vice President Osamu Yamada, will not seek re-election to the board next year. The men have an average age of 50.
