Hi! I'm a university student and I'm in Tokyo for an exchange. I was wondering if you guys know about cafes where I can study? Preferably a quiet area most parts of the day, with free wifi and plugs and of course a place where it's okay to stay for like 2 hours or so. THanks in advance! Btw, I live in Sendagaya but areas like Shinjuku, Harajuku and Shibuya are okay.
