One thing that's always bugged and perplexed me about anime is the really long episode titles in the original Japanese. For example, I used to be a big Dragonball Z fan, and the titles in English make a lot more sense to me than ones that are as many as 10 or 15 words. The latter seems a little excessive for an episode name.

Can anyone explain why Japanese anime creators do this with episode titles? It just seems like more work than necessary.

For example: "Goku's Ultimate Battle Draws Near!! Mystery of the New World Top Martial Arts Competition" (Japanese)/ "What is the Tournament?" (English)
