For example, I don't know what the average price of a co-working space is in Tokyo but I do know that "The Terminal" in Harajuku is only $150 a month. It's open from 11am to 11pm and includes free drinks (soda, coffee, tea).
Co-ba, has more than one location, the one in Shibuya is $160 a month and is open 24 hours.
The Open Source Cafe in Shimokitazawa is tiny but also similarly priced as is one I visited in Koenji (sorry, I forgot the name).
So, I'm curious where that $444 a month estimate comes from.
Rent is also iffy. It currently says $70 a day but rent varies widely depending on your standards and how far out of the center you're willing to live. I know people that have had a large 3bd apt for $1200 a month only 2 stops out various main lines on the express. (which might be like 12 local stops). Whereas downtown it might be $1200 for a studio but then again it depends on the quality. I know guys living in Nishi-Azabu for $600 a month.
