@LetMeRollIt are you Japanese? If you are would you have any objections to bringing in a non-japanese striker for the team?
Yes, I am. Thanks for the thought. In general if there's any good player, striker or otherwise, who happens to want to naturalize, personally I wouldn't mind at all. Would I accept a great gift? Of course.
But it's not like the government allows naturalization easily. Over the years there were several Brazilians who naturalized, but these guys had been playing in Japan for a long time. In case of Alex I thought he'd been here since he was a teenager or something. At least in Tulio Tanaka's case. And he was a Japanese-Brazilian.
Ramos Ruy who was the no.10 in the NT for the 94 American WC qualification played in the domestic league for years before we had J-league.
I don't know why any player who doesn't have any relevance to the country would want to become Japanese. And that shouldn't be our main strategy to make the NT better.
Football/soccer is really popular among sportive boys in our country. They seem to practice really hard, and they generally seem to have good technique, but we know the issues they often face at the international level; they're used to playing only mostly against fellow boys so they're not adapted to the more physical and aggressive opponents, guys that are simply bigger, stronger, taller, faster pushing and shoving you when you try to play, being intimidated and not being able to play confidently enough, etc.
One scene that stood out for me in the test match against Zambia yesterday was Kakitani being knocked down by a shoulder charge in the penalty box chasing a ball when the defender was not playing the ball at all. Kakitani is quite quick to run behind the line and has superb ball control, but he doesn't seem to be able to make an impact. Being knocked down like that would have been a foul all their lives they've played, so IMO you can't really blame them for not being prepared for that. (Such agression would generally raise eyebrows in our culture, you know generally we're supposed to be the polite kind of people, so you just don't grow up playing like that. Defenders don't pull the shirts to stop the attackers. Well, at least not before, may be the kids now have more "malicia" I don't know.)
We don't need one import who can overwhelm such defenders, we need a system to bring up whole bunch of players who can be like that. The players need to be exposed to the tough international stage at a much earlier phase, during their teens I think. Currently yes the best players will be selected to the NT at their ages and will experience several international games, but that's only a few games a year for 20 players or something. The good players will play in the NT in the Olympics or the WC, and some of them would get to go to Europe, but by then they'd be in their mid 20's or something, and then they have to adapt to the physicality.
I've read that the Mexican have their teenage NT play something like 50 international matches a year, for the players' experience. That's the sort of thing the Japanese NT needs to do I think. I want my NT to become stronger in a solid way in a long term plan.
