PSP is peak retro tech. The disk drive mechanism is so satisfying to open and close, popping out the UMD cartridge...
But yes, Japan preserves their old tech, books and games by default. Used items are almost always immaculately kept and sent cleaned up. It's pretty reliable to buy used in Japan.
Beautiful! Love those billboards. Also reminds me to check out a PSP Go, I bet the slide-out design is cool in person.
