While conventions like anime conventions are common in countries like Finland, the convention scene is more fragmented in Japan. There are industry-led conventions that focus on celebrities and merchandise, and fan-led events centered around doujinshi. Discussion spaces tend to be weaker and more closed-off compared to Western conventions. However, there are some exceptions like Niconico Chokaigi that aim to recreate online anime communities offline, and SF Taikai which has a sci-fi focus but anime influence. Overall, Japan lacks a single overarching convention space and the landscape is more specialized than in other countries.
