Philippe Troussier has achieved many things during his time in charge of the national team.
But one of them isn't finding a regular captain.
Tsuneyasu Miyamoto believes he has the answer to the Frenchman's problem: himself!
The Gamba Osaka defender is as smart and intelligent off the field as he is on it, and just relishes the responsibility of wearing the captain's arm band.
When asked if he would be leading the national team out for their friendly against Poland at the home stadium of Widzew Lodz on Wednesday, Miyamoto replied: ''I hope so.
''My position in the team is very important, so I must take big responsibility as a player.
''If I am made captain, then I must impose myself on the other players as well, but I enjoy that.''
It's unusual to find a Japanese player openly saying he wants to be the leader, and this attitude has not gone unnoticed by Troussier, who appointed him captain for the first time against Italy last November.
Miyamoto responded with an inspirational display, the highlight of which was an incredible goal-saving tackle on Francesco Totti as the Prince of Roma seemed certain to score from close range.
Miyamoto was not quite as assured in the 1-0 victory over Ukraine last Thursday, but he should retain his place in the continued absence through injury of Ryuzo Morioka.
The 25-year-old centre back appreciates he has a wonderful opportunity to book his slot in Japan's World Cup 23.
''Of course the injury to Morioka has given me a chance, but I was challenging for the position before that,'' he is quick to point out, and rightly so after running Troussier's oft-discussed flat back three in the 2-2 draw with Nigeria at Southampton last October and the 1-1 draw with Italy before Morioka got hurt.
''I understand the situation with Morioka, because I have had injuries of my own in the past.
''I have to show Philippe Troussier what I am capable of before Morioka returns from injury.''
Japan's flat three, which plays a very aggressive offside trap and pushes up quickly to deny the opposition space in midfield, is pivotal to the overall success of the team.
If the flat three system breaks down, the team is in trouble, but if it runs smoothly the opposition often do not know which way to turn.
Despite these pressures on the middle man, Miyamoto is more than willing to take the job on.
And the captain's arm band, too, please Monsieur.
