Is coworking a popular thing in big japanese cities? Being a salaryman since arriving in the country I haven't had any exposure to it.

However I noticed the place where the Tokyo iOS developer meeting happens every month would be perfect for co-working: many rooms of different sizes, enabling people to set up some group meetings whenever is needed.

Tokyo iOS Meetup organizer here. The place where we meet is a company called Voyage Group, which is actually a proper company rather than a co-working space. It is unique in that, as I understand it, it is made up mostly of small, wholly-owned subsidiary companies, which is why there are all of those different-sized rooms. You are right that it would be good for co-working, too.

Co-working spaces have definitely expanded in the past couple years though. Co-ba in Shibuya and Hub Tokyo in Meguro are two that I have visited that seemed like they had good communities.
