The Japanese union have come up with a list of 60 potential coaches to replace Eddie Jones including Fiji boss John McKee.
According to reports in Japan, there has been contact between McKee, who was the early frontrunner for the job before distancing himself.
However general secretary Noriyuki Sakamoto revealed that McKee is very much a candidate on the list of 60, which also includes around ten Japanese candidates which also includes former Bulls boss frans Ludeke.
The decision Jones' replacement will be taken in December, with the JRFU also having to decide on the coach of their Super Rugby franchise the Sunwolves.
"There have not been any negotiations (with McKee) but I won't say I haven't been in contact (with him)," Sakamoto told the Kyodo News.
"There has been contact from both sides, speaking with agents and things. We have to find out whether it is a possibility or not.
"Experience will count, but it doesn't have to include getting to the quarterfinals of the World Cup or something like that. If we made that requirement then there would be no Japanese candidates.
"(We are looking at) qualifications and knowledge. Apart from that, someone who has a knowledge of Japan, or someone like Eddie-san or (former coach John) Kirwan-san that has worked in Japan.
"(The candidate) will have to have an understanding of Japan's rugby culture. Finally, integrity will come into play. Then we will need someone that has a network."
