Do different nationalities have "notably" different play styles? In chess, noting the more common countries I've played (Indian Russia, Australia, France, US,  China, Japan etc) I've noticed some similarities in their play style. Like how Japanese players, from what I've seen, play aggressive pawns; France and US play the more typical tactics, China doesn't play gambits, and overall isn't rich in strategy.

While these may just be coincidence, Is there enough similarity within a nationality that it's notable?
Consider this quote from wikipedia regarding the Soviet Chess School:


  The main contribution of the Soviet School of Chess was not the style of players but their emphasis on rigorous training and study of the game, i.e. considering chess a sport rather than an art or science.


Emphasis is mine.

Given that chess is taught as a school subject in Russia, then this points to there not being trends in chess style by country.

Moreover there seems to be little evidence that openings named after regions are done so because of their popularity there. If this were the case, then Scandinavians would tend to play the scandinavian-defense, which has a different style to the italian-game. In fact, the Scandinavian is called such because it was first seriously analysed by Scandinavian masters.
