In the first episode of the anime, Mugi is making a big deal out of mixing her fries with those of the other two girls. In Japanese culture, sharing your food with the group is a sign that you accept the group as your own, so Mugi was both being formal and very sweet in one go.
The train station seen most in the series, which is the one Mugi uses for commuting, is the Shugakuin Station on the Eizan Electric Railway in Kyoto.
The high school is based on an elementary school in Toyosato in the Shiga prefecture. The building was supposed to be torn down, but after protests from the local community it got renovated and opened for the public, and it now serves as a museum. It's needless to say that the building is now a very popular destination for fans of the series.
The Max Burger fast food restaurant frequented by the girls is based on a real-life McDonald's.
In episode 5 of the first season, Sawako plays her super flashy solo. However, the way she moves her arm while "speed picking" is something more akin to new guitar players. Faster playing is done using mostly the fingers or the wrist, Sawako's using her arm almost exclusively.
The place where the girls go to feed the Japanese monkeys, as seen in in episode 4 of the second season, is the Iwatayama Monkey Park in Kyoto, situated on top of Mt. Arashiyama. It is pretty much as depicted, including the splendid view of the city.
The statue seen at the very end of episode 7 of the second season is based on a statue of◊ William S. Clark, the founder of Sapporo Agricultural College (now Hokkaido University), which implies that Sokabe-sempai is studying in Sapporo. Also, the full version of "Cagayake!GIRLS" contains the words "Girls, be ambitious", which is a reference to Clark's famous parting words to his students ("Boys, be ambitious!").
The festival the girls and Sawako attend in episode 12 of the second season is based on the Fuji Rock Festival, which is held annually in the Naeba Ski Resort, in the Niigata Prefecture of Japan.
Cash Cow Franchise: April, 2010. The pre-orders for the yet-to-be-released DVDs of K-On second season occupied ten of the Top 13 most bought movies in amazon.com Japan. And this is only after the first episode of season 2 has aired, folks. The momentum of success and die-hard fandom set by Season 1 in 2009 does not look like it will slow down any time soon, with twenty six episodes in this season altogether.
There's a movie coming out soon. Guess what the general reaction from the fans was...
It's getting worse and worse. K-On model plane, K-On video game...
There're also character cookies (quite horrifying when you realize you're basically eating the girls in cookie form), as well as Giitah cookies (yes, you CAN eat Yui's guitar), and other assorted snack foods. Now with pictures.◊
Defictionalization : A cassette with the tracklist the band put together in season 2 episode 23 was released three weeks after the series ended its broadcast run.
Sawako Yamanaka (Karen Strassman) and Nodoka Manabe (Laura Bailey) teamed up in Sakura Wars as two of the six combat pilots in the New York-based Star Division, while Mio Akiyama (Cristina Vee) fittingly worked behind the scenes as one of the team's support personnel.
The Japanese voice actresses of the 4 main girls have appeared in Hyouka as of Episode 14.
Also, their voice actresses also worked in the Queen's Blade franchise, albeit not everyone at the same time.
Though Aki Toyosaki seems to have avoided the typecasting that typically comes with successful roles; presently she has a tendency of taking perverted and sultry seductresses who are nowhere as sweet and innocent as Yui is.
