Kinda curious about your social life there as I would like to ask if it is easy to blend into their social circle and how approachable Japanese people are? Would there be any language or racial barrier? Currently last year of high school and planning to study in Japan.

Hey there, sorry for the late reply! Been really busy these days 

I mean its really the same anywhere you go around the world, there will be people whom you meet who doesn't really match up with your personality and people who you get along great! No language barriers for me as I speak Japanese fluently, but I do notice some racial barriers (especially from the older generation) if you don't look asian, but I would suggest that you don't mind it.
Thank you for replying in my stead!

Regarding the "inside" and "outside", I feel like that if you've integrated yourself into Japanese society fully (language, customs, culture) while also knowing that you yourself are a foreigner, the Japanese tend to want to put you into the "in" circle rather than treat you as an outsider. I tend to delve myself into the local culture but still keeping my Malaysian identity, and I feel that a lot of Japanese treat me as one of their own rather than a foreigner
