Interesting to see how Tokyo work culture impacts the co-working scene: A lot of them only open at 10 but stay open late in the evening. This is because, due to its size and property prices, many people commute up to 2 hours one way.
I don't follow. I know many salarypeople who have 1.5h+ commutes, because as you say central Tokyo is expensive. But if you're self-employed or doing a startup, why would you travel that far to a co-working space instead of just working from home?
