Chihayafuru/Karuta club
Though categorised as a girls' comic and attracting many female readers, Chihayafuru is also very popular among boys. Karuta clubs are a new phenomenon in Japan, where a national karuta competition takes place every year. The comics first came out in 2007 and the anime version launched in 2011, leading to a threefold rise in karuta competitors across Japan. A live-action film based on the series was released this year, attesting to the popularity of a series that makes for a great example of friends with a common interest coming together to set up a club.
