Yokohama was visited by Alejandro Agag in the last week for meetings to try and reach an agreement on hosting the first ever all-electric race in the country.

A delegation from the Dentsu company, which is believed to be involved in hosting a race in Japan, was in Hong Kong conducting meetings with Formula E officials over the weekend.

“The discussions were good last week and Yokohama looks strong, but I would be happy with either of Yokohama or Tokyo for our first event," Agag told Motorsport.com.

"It is important to race in Japan at some stage. We are open to both, but the problem is that the police are very strict for permissions,

"So we hope we can do something for season five at the earliest, we are making progress.”

The potential entry of a Japanese manufacturer ahead of that date is believed to be pushing on discussions to have a race in the country.

Honda and Nissan are believed to be the most likely to make the leap in to Formula E.

Agag would not be drawn on when such an announcement might come, but a leading series source indicated to Motorsport.com that it could come before the end of the current season.
