The Kochi Ramen Festival brings ramen types from across Japan to Shikoku. This year's event has twenty participants who span the country, from Hokkaido to Kyushu and various spots in between. The ramen varieties themselves also offer a great deal of individuality, and the official event website has all of the options listed if you want to scope them out in advance.
One particularly nice element of this festival is the duration. It spans a ten day period, allowing ramen aficionados the chance to sample a wider range of the event's offerings.
