Eddie Jones believes the Japan Rugby Football Union must not waste a glorious opportunity to build on some of the successes of the World Cup.
The Brave Blossoms wrote one of the stories of the World Cup when they beat two-time champions South Africa in their opening Pool B fixture ten days ago. The result met with considerable excitement from the Japanese rugby fraternity.
Jones said it was now incumbent upon the JRFU to improve their structures and ensure that the opportunity to increase the profile of the sport in that country is not wasted. However, the coach does not appear confident that this opportunity for growth will be exploited.
"The legacy now is how the Japan Rugby Football Union uses the win and how strong they are in developing good coaching systems and improving infrastructure to go forward," Jones told the Kyodo News.
"This is like a balloon. It can be popped or it can be a real growth spurt. It's entirely the responsibility of the JRFU," added Jones.
While Jones is partially satisfied by the progress made with the resources at his disposal, he thinks there is still considerable room for the improvement of the rugby structures in that country. What will upset him, is the failure to implement change.
"To keep improving, things have to change. I couldn't go back after the World Cup and do what I have done for the last four years because we are not going to improve enough within the current structures. I know enough about rugby to know that," said Jones.
Jones suggested the notion that the Japan national team were merely representatives of the country needed to be addressed, adding that there was more to it than just that.
"One of the reasons I decided not to continue was because I didn't think those things could change," explained Jones, who has since taken up a coaching job with the Stormers.
