Japan's first woman governor has thrown down a challenge to the traditionally male world of sumo wrestling.

Fusae Ota, who was elected governor of the city of Osaka three days ago, says she wants to follow the example of previous governors and present an award at sumo wrestling championships next month.

But this is being opposed by the wrestlers themselves because Governor Ota would have to step inside the clay circle, where matches take place.

The circle is regarded by sumo wrestlers as sacred and has traditionally been out of bounds to women. The Osaka Sumo Wrestling Association says it's just trying to protect its traditional culture by excluding women.

But a BBC correspondent in Tokyo says it may find it difficult to resist the growing drive in Japan for sexual equality.
