What do you struggle with in Japan?

Hi y'all. I'm Japanese. It might be weird to post something here from Japanese but I'm curious what the life in Japan is like as a foreigner. Of course living outside of your home country is difficult. But Japan has so many rules (many of them unwritten), a unique culture and the language is difficult especially for English speakers. I also struggled when I lived outside of Japan because of Japan is such a weird country I would say.
Please share what you're struggle in a daily life.
