These things, especially price and plastic are certainly true... but Japan is ABSOLUTELY incredible and I'd love a piece like this to also share some of the things you found amazing if you're going to focus on what bothered you most.

I've spent a few months in Japan in total and just off the top of my head... the food, whiskey, saki, sushi, architecture, history, temples, nature, convience store situation (family mart is incredible), bike culture, public transport system, loud restaurant greetings, and animal cafes are all amazing.

For me there are far more positives to point out then negatives when it comes to Japan.
