The group opposing Japan Amateur Boxing Federation chairman Akira Yamane is looking for a complete systematic transformation of the JABF. Otherwise, they feel, the very existence of the sport in Japan could be in jeopardy going forward.

That said, the members are not content with only Yamane's resignation on Wednesday in Osaka, which came a few hours before they held their own news conference in Tokyo.

The group was cautious in its reaction to Yamane's resignation.
