I'm not a native English speaker, so I don't really know why, or if, there's a problem for native English speakers to learn or "get" pitch accent. For speakers of many other European languages Japanese pitch accent is not tricky. You listen, and then you speak. Just as you would listen to English, and repeat it the same way.

Japanese, despite being extremely logical and so beautiful in so many ways, is still hard to learn for me, and of course learning the writing system is not done in the blink of an eye (unlike the Latin-based writing system we use), but pitch accent isn't really the problem here.
