Virtually every Japanese school story will, at some point, depicts school clubs at some points. And said clubs will be very varied in nature. There will be sport clubs for the msot common sports, but there will also be 'cultural clubs' for the a whole range of random thing. Music, cooking, theater, computer, shogi...
In the American high school I've seem*
, not only clubs were not as present, but it were almost always centered around sports. There is always an American Football team and, sometimes, a Baseball Team as well, as well as cheerleaders around them. But that is it.
Also, the way I understand, Japanese school incentive is students to be part of clubs. Hell, apparently it is somewhat common being mandatory to be a club member.
Finally, when watching American school shows, there sport teams never seemed weird to me. The cheerleaders were, natrually, but only them. All the rest seemed very natural. However, I found Japanese clubs to be a very foreign in concept. It caused me weirdness. So, yeah, I think a page clarifying the issue to be useful overall.
