Dude. Japan is an amazing country. Their kids are well-educated, their technology is top-tier, and their economy is very good compared to most countries in the world. Especially considering how they built up from wreckage after WWII they're insanely impressive. Now they've got an overworking problem, partly because they used to have to work like crazy to build their country up again. They've got a suicide problem, and a low birthrate problem. All cultures have problems. Doesn't change the fact that they've achieved some amazing things. Oh yeah, and my sister who lived there for a few months said their cities are really nice and clean compared to the USA.
The Japanese, as is common in Asian cultures, are collectivists. You value individualism and standing up for yourself. Their culture values harmony and getting along instead, team success rather than individual success. Causing a fuss and standing up for "your rights" would be frowned upon. As others have said, one person against the whole system and culture wouldn't get you anywhere. Your life also depends on getting along with others well enough to participate in society.
