True. But I did mention that they were also friendly. I had no issue getting into all sorts of activities with them. From playing the Shamisen to practicing Sadō. I had lots of friends who would help me out in all sorts of things, such as the University entrance exam, moving stuff, and translation.
I’m speaking of my experiences of course. I come from a different cultural background (Arab). I lived in both the US and Japan, and in almost all aspects except employment and income, I prefer Japan. Your mileage may vary.
