Can you use a Japanese PSP in America?

Excuse me, I have a question regarding the use of a PSP, specifically a Japanese model, in the United States. I'm curious to know if it's possible to use one there without any compatibility issues or regional restrictions. Are there any additional steps or requirements that I need to be aware of? Additionally, are there any limitations or challenges that I might encounter when trying to access content or features that are specific to the Japanese market? Your insight on this matter would be greatly appreciated.
