Tokyo’s Olympic organizing committee is moving closer to pushing sponsors to declare gender equality and diversity goals as it looks to overcome a series of public gaffes.

The organizer of the Tokyo Games plans to unveil its own pledge to advance equality and inclusion next month, Chief Executive Officer Toshiro Muto said at a briefing earlier in the week, without elaborating. Mikako Kotani, who leads the organizer’s push to promote gender equality, said in a March interview that the Tokyo committee would follow up by asking sponsor companies, sports bodies and educational institutions to unveil their own targets.

While neither Kotani nor Muto mentioned any specific companies, the ranks of Tokyo 2020 sponsors include some of Japan’s biggest corporate names. Among them are Toyota Motor Corp., Nomura Holdings Inc., Fujitsu Ltd., Canon Inc. and NEC Corp.
