Prime Minister Sanae Takaichi on Wednesday vowed to make every effort to create an environment conducive to wage increases, speaking at her first May Day event since taking office last autumn.

The prime minister also called for cooperation to achieve "sustained wage hikes that outpace inflation."

The May Day central convention was held by the Japanese Trade Union Confederation, the umbrella organization for labor unions in Japan known as Rengo, at Yoyogi Park in Tokyo.
